+
+## Overview
+
+The Wago Stepper Controllers (750-671 and 750-672) drive stepper motors via EtherCAT. This documentation focuses on **velocity/speed control mode** implementation.
+
+### Key Differences Between Models
+
+| Feature         | 750-671                                    | 750-672                              |
+| --------------- | ------------------------------------------ | ------------------------------------ |
+| Max Voltage     | 50 VDC                                     | 70 VDC                               |
+| Max Current     | 5 A                                        | 7.5 A                                |
+| Speed Control   | Via Application Selector in config         | Via Control Byte C1 command          |
+| Control Byte C1 | Different bit layout (M_Speed_Control bit) | Command field (0x18 = Speed Control) |
+
+**For 750-671:** Must set `Application_Selector = 2` and `PWM_Period = 0` in WAGO I/O CHECK before using speed control.
+
+**For 750-672:** Speed control is selected directly via command in Control Byte C1 (no config needed).
+
+### Process Image
+
+Both models use **12 bytes bidirectional** (96 bits each way):
+
+```
+Input (TxPDO - Controller → PLC):
+ [0] S0 (status)
+ [1] Reserved
+ [2-3] Actual Velocity (i16)
+ [4-5] Reserved
+ [6-8] Actual Position (24-bit: L, M, H)
+ [9] S3 (digital inputs, warnings)
+ [10] S2 (busy, error, on_speed, etc.)
+ [11] S1 (acknowledgments)
+
+Output (RxPDO - PLC → Controller):
+ [0] C0 (control)
+ [1] Reserved
+ [2-3] Target Velocity (i16, clamped to ±25000)
+ [4-5] Acceleration (u16)
+ [6-8] Position (24-bit: L, M, H)
+ [9] C3 (position/reset control)
+ [10] C2 (prescalers, error quit)
+ [11] C1 (main control: enable, start, mode)
+```

+## Hardware Quick Reference
+
+### Connections
+
+| Pin | Name | Purpose |
+|-----|------|---------|
+| DI1+ | Digital Input 1 | Enable input (connect to 24V or control via software) |
+| DI2+ | Digital Input 2 | Referencing input |
+| DI- | Ground | Reference potential for DI1/DI2 |
+| A1, A2 | Motor Winding A | Connect to motor phase A |
+| B1, B2 | Motor Winding B | Connect to motor phase B |
+
+### Status LEDs
+
+- **LED H:** Shows error codes via blink patterns (see Wago manual section 3.3 for error codes)
+- Other LEDs show Ready, Enable, Busy states (see manual section 2.1.2.3)

+    pub txpdo: Wago750_672TxPdo,  // Data we receive
+    module: Option<Module>,
+    pub state: InitState,
+    pub initialized: bool,
+}
+```
+
+**Responsibilities:**
+- Implements EtherCAT device traits
+- Handles bit-level I/O with process image
+- Runs state machine in `input()` method
+- Thread-safe (used via `Arc<RwLock<>>`)
+
+#### 2. `StepperVelocityWago750672` Wrapper
+
+Located in `io/stepper_velocity_wago_750_672.rs`
+
+```rust
+pub struct StepperVelocityWago750672 {
+    pub device: Arc<RwLock<Wago750_672>>,
+    pub state: InitState,
+    pub target_velocity: i16,
+    pub target_acceleration: u16,
+    pub enabled: bool,
+    pub freq_range_sel: u8,
+    pub acc_range_sel: u8,
+}
+```
+
+**Responsibilities:**
+- Provides high-level API (`set_velocity()`, `set_enabled()`)
+- Manages prescaler settings
+- Abstracts away state machine complexity
+
+### Why Two Layers?
+
+1. **`Wago750_672`:** Low-level EtherCAT device that handles cycle-by-cycle I/O
+2. **`StepperVelocityWago750672`:** High-level wrapper for application logic
+
+This separation allows:
+- EtherCAT device to run in tight real-time loop
+- Application code to use simple API without worrying about cycles/acknowledgments
+- Easy testing of each layer independently

+
+## Control & Status Bytes
+
+### Design Pattern: Type-Safe Byte Construction
+
+Instead of hardcoding hex values like `0x1B`, we use builder pattern with enums:
+
+```rust
+// ❌ BAD - magic numbers, error-prone
+dev.rxpdo.c1 = 0x1B;
+
+// ✅ GOOD - explicit, self-documenting
+let c1 = ControlByteC1::new()
+    .with_flag(C1Flag::Enable)
+    .with_flag(C1Flag::Stop2N)
+    .with_command(C1Command::SpeedControl)
+    .bits();
+dev.rxpdo.c1 = c1;
+```
+
+### Wago 750-672 Control Bytes
+
+#### Control Byte C1 (Offset 11) - Main Control
+
+```rust
+pub struct ControlByteC1(u8);
+
+pub enum C1Flag {
+    Enable = 0b0000_0001,  // Bit 0: Must be 1 to enable
+    Stop2N = 0b0000_0010,  // Bit 1: Must be 1 for normal operation
+    Start  = 0b0000_0100,  // Bit 2: Rising edge triggers action
+}
+
+pub enum C1Command {
+    Idle          = 0b0000_0000,  // Bits 3-7: Operating mode
+    SinglePosition = 0b0000_1000,
+    RunProgram    = 0b0001_0000,
+    SpeedControl  = 0b0001_1000,  // ← We use this
+    Reference     = 0b0010_0000,
+    JogMode       = 0b0010_1000,
+    Mailbox       = 0b0011_0000,
+}
+```
+
+**Implementation:**
+
+```rust
+impl ControlByteC1 {
+    pub const fn new() -> Self {
+        Self(0)
+    }
+
+    pub const fn with_flag(mut self, flag: C1Flag) -> Self {
+        self.0 |= flag as u8;  // OR in the bit
+        self
+    }
+
+    pub const fn with_command(mut self, cmd: C1Command) -> Self {
+        self.0 = (self.0 & 0b0000_0111) | (cmd as u8);  // Mask lower 3 bits, set upper 5
+        self
+    }
+
+    pub const fn bits(self) -> u8 {
+        self.0
+    }
+}
+```
+
+**Key Points:**
+- `const fn` allows compile-time evaluation
+- Chainable builder pattern
+- Command overwrites bits 3-7 while preserving 0-2
+- Flags are additive (multiple can be set)
+
+#### Control Byte C2 (Offset 10) - Prescalers & Error Handling
+
+```rust
+pub struct ControlByteC2(u8);
+
+pub enum C2Flag {
+    FreqRangeSelL = 0b0000_0001,  // Bit 0: Freq prescaler LSB
+    FreqRangeSelH = 0b0000_0010,  // Bit 1: Freq prescaler MSB
+    AccRangeSelL  = 0b0000_0100,  // Bit 2: Acc prescaler LSB
+    AccRangeSelH  = 0b0000_1000,  // Bit 3: Acc prescaler MSB
+    PreCalc       = 0b0100_0000,  // Bit 6: Pre-calculation
+    ErrorQuit     = 0b1000_0000,  // Bit 7: Acknowledge error
+}
+
+impl ControlByteC2 {
+    pub const fn with_freq_range(mut self, sel: u8) -> Self {
+        self.0 = (self.0 & 0b1111_1100) | (sel & 0b0000_0011);
+        self
+    }
+
+    pub const fn with_acc_range(mut self, sel: u8) -> Self {
+        self.0 = (self.0 & 0b1111_0011) | ((sel & 0b0000_0011) << 2);
+        self
+    }
+}
+```
+
+**Critical:** Prescalers can only be changed when controller is **disabled** (before Enable state).
+
+#### Control Byte C3 (Offset 9) - Position & Reset
+
+```rust
+pub struct ControlByteC3(u8);
+
+pub enum C3Flag {
+    SetActualPos = 0b0000_0001,  // Bit 0: Set current position
+    DirectionPos = 0b0000_0010,  // Bit 2: Force positive direction
+    DirectionNeg = 0b0000_0100,  // Bit 3: Force negative direction
+    ResetQuit    = 0b1000_0000,  // Bit 7: Acknowledge reset
+}
+```
+
+### Status Bytes (Read-Only)
+
+#### Status Byte S1 (Offset 11) - Acknowledgments
+
+```rust
+pub struct StatusByteS1(u8);
+
+pub enum S1Flag {
+    Ready      = 0b0000_0001,  // Bit 0: Acknowledges Enable
+    Stop2NAck  = 0b0000_0010,  // Bit 1: Acknowledges Stop2_N
+    StartAck   = 0b0000_0100,  // Bit 2: Acknowledges Start
+}
+// Bits 3-7: Mirrors C1 command when acknowledged
+
+impl StatusByteS1 {
+    pub const fn has_flag(self, flag: S1Flag) -> bool {
+        (self.0 & flag as u8) != 0
+    }
+}
+```
+
+**Usage Pattern:**
+```rust
+// Wait for acknowledgment
+if self.txpdo.s1 == c1 {
+    // All bits acknowledged, proceed
+}
+```
+
+#### Status Byte S2 (Offset 10) - Operation Status
+
+```rust
+pub struct StatusByteS2(u8);
+
+pub enum S2Flag {
+    OnTarget    = 0b0000_0001,  // Bit 0: Position reached (positioning mode)
+    Busy        = 0b0000_0010,  // Bit 1: Executing command
+    StandStill  = 0b0000_0100,  // Bit 2: Motor not moving
+    OnSpeed     = 0b0000_1000,  // Bit 3: Target velocity reached
+    Direction   = 0b0001_0000,  // Bit 4: Rotation direction (0=neg, 1=pos)
+    ReferenceOk = 0b0010_0000,  // Bit 5: Referencing complete
+    PreCalcAck  = 0b0100_0000,  // Bit 6: Pre-calc acknowledged
+    Error       = 0b1000_0000,  // Bit 7: Error occurred (check LED H)
+}
+```
+
+**Critical for velocity control:** Monitor `OnSpeed` bit to know when target velocity is reached.
+
+#### Status Byte S3 (Offset 9) - Digital Inputs & Warnings
+
+```rust
+pub struct StatusByteS3(u8);
+
+pub enum S3Flag {
+    Input1  = 0b0000_0001,  // Bits 0-5: Digital input states
+    Input2  = 0b0000_0010,
+    Input3  = 0b0000_0100,
+    Input4  = 0b0000_1000,
+    Input5  = 0b0001_0000,
+    Input6  = 0b0010_0000,
+    Warning = 0b0100_0000,  // Bit 6: Warning condition
+    Reset   = 0b1000_0000,  // Bit 7: Reset requested
+}
+```
+
+---
+
+## Implementation Details
+
+### Critical Initialization Sequence
+
+⚠️ **This sequence MUST be followed exactly or the controller won't work:**
+
+1. **Set non-zero acceleration** (before enabling)
+2. **Set Enable + Stop2_N** (wait for ack)
+3. **Set operating mode** (0x18 for speed control, wait for ack)
+4. **Issue Start pulse** (set to 1, wait for ack, set to 0, wait for ack clear)
+5. **Running** (repeat step 4 every time velocity changes)
+
+### State Machine (Why It Exists)
+
+The state machine exists because **acknowledgments happen in different EtherCAT cycles**. You can't just set everything in one cycle.
+
+```rust
+#[derive(Debug, Clone)]
+pub enum InitState {
+    Off,               // Controller disabled
+    Enable,            // Setting Enable + Stop2_N, waiting for ack
+    SetMode,           // Setting speed control mode, waiting for ack
+    StartPulseStart,   // Setting Start bit, waiting for ack
+    StartPulseEnd,     // Clearing Start bit, waiting for ack clear
+    Running,           // Normal operation
+    ErrorQuit,         // Handling error
+    ResetQuit,         // Handling reset
+}
+```
+
+### State Machine Implementation
+
+Located in `Wago750_672::input()` method (runs every EtherCAT cycle):
+
+```rust
+fn input(&mut self, input: &BitSlice) -> Result<(), anyhow::Error> {
+    // 1. Read process image from controller
+    let base = self.tx_bit_offset;
+    let mut b = [0u8; 12];
+    for i in 0..12 {
+        b[i] = input[base + i * 8..base + (i + 1) * 8].load_le();
+    }
+    
+    self.txpdo = Wago750_672TxPdo {
+        s0: b[0],

+        s1: b[11],
+    };
+
+    // 2. State machine logic
+    match self.state {
+        InitState::Off => {

+            self.rxpdo.c1 = c1;
+            
+            // Wait for mode acknowledgment
+            if self.txpdo.s1 == c1 {
+                self.initialized = true;
+                self.state = InitState::StartPulseStart;
+            }
+        }
+        
+        InitState::StartPulseStart => {

+                .with_command(C1Command::SpeedControl)

+        InitState::StartPulseEnd => {
+            // Clear Start bit

+                .bits();
+            self.rxpdo.c1 = c1;
+            
+            // Wait for acknowledgment to clear
+            if self.txpdo.s1 == c1 {
+                self.state = InitState::Running;
+            }
+        }
+        
+        InitState::Running => {
+            // Monitor for errors and resets
+            let c2_error_mask = ControlByteC2::new().with_flag(C2Flag::ErrorQuit).bits();
+            let c3_reset_mask = ControlByteC3::new().with_flag(C3Flag::ResetQuit).bits();
+            
+            if self.txpdo.s2 & c2_error_mask != 0 {
+                self.state = InitState::ErrorQuit;
+            } else if self.txpdo.s3 & c3_reset_mask != 0 {
+                self.state = InitState::ResetQuit;
+            }
+        }
+        
+        InitState::ErrorQuit => {
+            // Set Error_Quit bit to acknowledge
+            self.rxpdo.c2 |= ControlByteC2::new().with_flag(C2Flag::ErrorQuit).bits();
+            tracing::error!("Stepper Controller Errored. Trying to reenable...");
+            self.state = InitState::Enable;  // Restart initialization
+        }
+        
+        InitState::ResetQuit => {
+            // Set Reset_Quit bit to acknowledge
+            self.rxpdo.c3 |= ControlByteC3::new().with_flag(C3Flag::ResetQuit).bits();
+            tracing::error!("Stepper Controller Reset. Trying to reenable...");
+            self.state = InitState::Enable;  // Restart initialization
+        }
+    }
+    
+    Ok(())
+}
+```
+
+**Key Implementation Notes:**
+
+1. **State changes happen AFTER acknowledgment:** We wait for `self.txpdo.s1 == c1` before moving to next state
+2. **Enable and Stop2_N stay high:** They're included in every C1 byte after Enable state
+3. **Start pulse is a rising edge:** Must go 1 → 0, not just stay at 1
+4. **Error recovery:** Automatically attempts to re-enable on error/reset
+
+### High-Level API Implementation
+
+Located in `StepperVelocityWago750672`:
+
+```rust
+pub fn set_enabled(&mut self, enabled: bool) {
+    // Prevent redundant enables
+    if self.enabled && enabled {
+        return;
+    }
+    
+    // Safety check: acceleration must be non-zero
+    if self.get_target_acceleration() == 0 {
+        return;
+    }
+    
+    self.enabled = enabled;
+    if enabled {
+        self.change_init_state(InitState::Enable);
+    } else {
+        self.change_init_state(InitState::Off);
+        self.write_control_byte(ControlByte::C1, 0b00000000);
+    }
+}
+
+pub fn set_velocity(&mut self, velocity: i16) {
+    self.target_velocity = velocity;
+    
+    let mut dev = block_on(self.device.write());
+    
+    // Clamp to valid range
+    dev.rxpdo.velocity = velocity.clamp(-25000, 25000);
+    
+    // Trigger Start pulse if already initialized
+    if dev.initialized {
+        dev.state = InitState::StartPulseStart;
+    }
+}
+
+pub fn set_acceleration(&mut self, acceleration: u16) {
+    self.target_acceleration = acceleration;
+    
+    let mut dev = block_on(self.device.write());
+    dev.rxpdo.acceleration = acceleration;
+}
+```
+
+**Why the wrapper?**
+- Application code doesn't need to know about state machine
+- Handles common errors (zero acceleration check)
+- Thread-safe access to device
+- Clamping and validation in one place
+
+### Changing Velocity at Runtime
+
+⚠️ **Critical:** Must issue a **new Start pulse** for every velocity change:
+
+```rust
+// User calls this
+stepper.set_velocity(15000);
+
+// Internally, set_velocity() does:
+dev.rxpdo.velocity = 15000;
+if dev.initialized {
+    dev.state = InitState::StartPulseStart;  // ← Triggers new pulse
+}
+
+// State machine then handles:
+// StartPulseStart → StartPulseEnd → Running
+// (Takes 2-3 EtherCAT cycles)
+```
+
+**Common mistake:** Setting velocity without triggering Start pulse - motor won't change speed.
+
+---
+
+## Prescalers & Calculations
+
+Prescalers scale the velocity and acceleration values. They **can only be changed when disabled**.
+
+### Frequency Prescaler (Bits 0-1 of C2)
+
+Controls velocity scaling:
+
+| Freq_Range_Sel | Prescaler | Max Frequency | Resolution |
+|----------------|-----------|---------------|------------|
+| 00 | 200 (default) | 10 kHz | Configurable |
+| 01 | 80 | 25 kHz | 1 Hz |
+| 10 | 20 | 100 kHz | 20 Hz |
+| 11 | 4 | 500 kHz | 20 Hz |
+
+**Formula:**
+```
+Output Frequency (fp) = Velocity × 80 / Freq_Prescaler [Hz]
+```
+
+**Example:**
+```rust
+// Freq_Range_Sel = 01 (prescaler = 80)
+// Velocity = 10000
+// Output: 10000 × 80 / 80 = 10000 Hz
+
+stepper.set_freq_range_sel(1);  // Must be done BEFORE enable
+stepper.set_velocity(10000);
+```
+
+### Acceleration Prescaler (Bits 2-3 of C2)
+
+Controls acceleration scaling:
+
+| Acc_Range_Sel | Multiplier | Time to Max Speed |
+|---------------|------------|-------------------|
+| 00 | 8 (default) | 7600 ms |
+| 01 | 80 | 760 ms |
+| 10 | 800 | 76 ms |
+| 11 | 8000 | 7.6 ms |
+
+**Formula:**
+```
+Acceleration (a) = Acceleration_Value × Acc_Multiplier / Freq_Prescaler [Hz/s]
+```
+
+**Example:**
+```rust
+// Acc_Range_Sel = 01 (multiplier = 80)
+// Freq_Range_Sel = 01 (prescaler = 80)
+// Acceleration_Value = 10000
+// Output: 10000 × 80 / 80 = 10000 Hz/s
+
+stepper.set_acc_range_sel(1);   // Must be done BEFORE enable
+stepper.set_acceleration(10000);
+```
+
+### Setting Prescalers (Implementation)
+
+```rust
+pub fn set_freq_range_sel(&mut self, factor: u8) {
+    // Safety checks
+    if self.enabled || factor > 3 {
+        return;  // Can't change while enabled
+    }
+    
+    self.freq_range_sel = factor;
+    
+    let mut dev = block_on(self.device.write());
+    let c2 = ControlByteC2::from_bits(dev.rxpdo.c2)
+        .with_freq_range(factor)
+        .bits();
+    dev.rxpdo.c2 = c2;
+}
+
+pub fn set_acc_range_sel(&mut self, factor: u8) {
+    if self.enabled || factor > 3 {
+        return;
+    }
+    
+    self.acc_range_sel = factor;
+    
+    let mut dev = block_on(self.device.write());
+    let c2 = ControlByteC2::from_bits(dev.rxpdo.c2)
+        .with_acc_range(factor)
+        .bits();
+    dev.rxpdo.c2 = c2;
+}
+```
+
+**Usage:**
+```rust
+let mut stepper = StepperVelocityWago750672::new(device);
+
+// Set prescalers FIRST (before enabling)
+stepper.set_freq_range_sel(1);
+stepper.set_acc_range_sel(1);
+stepper.set_acceleration(10000);
+
+// Then enable
+stepper.set_enabled(true);
+
+// Now can set velocity
+stepper.set_velocity(15000);
+```
+

+## Common Pitfalls & Debug Tips
+
+### 1. Controller Won't Enable
+
+**Symptoms:**
+- State stuck in `Enable`
+- `initialized` never becomes true
+- Motor doesn't move
+
+**Debug checklist:**
+```rust
+// Check acceleration is non-zero
+println!("Acceleration: {}", dev.rxpdo.acceleration);  // Must be > 0
+
+// Check DI1 if hardware enable is configured
+println!("DI1 state: {}", (dev.txpdo.s3 & 0x01) != 0);  // Should be 1
+
+// Check status byte acknowledgment
+println!("C1: {:#010b}", dev.rxpdo.c1);
+println!("S1: {:#010b}", dev.txpdo.s1);  // Should match C1
+```
+
+**Common causes:**
+```rust
+// ❌ Forgot to set acceleration
+stepper.set_acceleration(0);  // Won't enable!
+
+// ✅ Always set non-zero acceleration
+stepper.set_acceleration(10000);
+stepper.set_enabled(true);
+```
+
+### 2. Velocity Won't Change
+
+**Symptoms:**
+	- Motor running but won't change speed
+- `set_velocity()` called but no effect
+
+**Debug:**
+```rust
+// Check initialized flag
+println!("Initialized: {}", dev.initialized);
+
+// Check state after velocity change
+println!("State: {:?}", dev.state);  // Should become StartPulseStart
+
+// Manually trigger Start pulse (bypass wrapper)
+dev.state = InitState::StartPulseStart;
+```
+
+**Common causes:**
+```rust
+// ❌ Setting velocity before initialization
+stepper.set_velocity(10000);  // Controller not ready yet
+
+// ✅ Check initialized first
+if stepper.device.read().initialized {
+    stepper.set_velocity(10000);
+}
+```
+
+### 3. Prescaler Not Working
+
+**Symptoms:**
+- Velocity calculation seems wrong
+- Can't reach expected frequency
+
+**Debug:**
+```rust
+// Check prescalers were set BEFORE enabling
+println!("Freq prescaler: {}", stepper.freq_range_sel);
+println!("Acc prescaler: {}", stepper.acc_range_sel);
+println!("Enabled: {}", stepper.enabled);
+
+// Check C2 byte
+let dev = stepper.device.read();
+println!("C2: {:#010b}", dev.rxpdo.c2);
+// Bits 0-1: freq, Bits 2-3: acc
+```
+
+**Common causes:**
+```rust
+// ❌ Setting prescaler after enable
+stepper.set_enabled(true);
+stepper.set_freq_range_sel(1);  // Too late! Ignored.
+
+// ✅ Set prescalers FIRST
+stepper.set_freq_range_sel(1);
+stepper.set_acc_range_sel(1);
+stepper.set_enabled(true);
+```
+
+### 4. State Machine Stuck
+
+**Symptoms:**
+- State doesn't progress
+- Acknowledgments not received
+
+**Debug:**
+```rust
+// Add logging to state machine
+match self.state {
+    InitState::Enable => {
+        println!("Enable state: C1={:#010b}, S1={:#010b}", self.rxpdo.c1, self.txpdo.s1);
+        // ...
+    }
+}
+
+// Check EtherCAT communication
+// - Is cycle running?
+// - Are other devices working?
+// - Check bus topology
+```
+
+### 5. Error Bit Set
+
+**Symptoms:**
+- Error bit (S2 bit 7) is 1
+- LED H blinking
+- Controller stops
+
+**Debug:**
+```rust
+// Check error state
+let s2 = StatusByteS2::from_bits(dev.txpdo.s2);
+if s2.has_flag(S2Flag::Error) {
+    println!("ERROR DETECTED");
+    
+    // Count LED H blinks for error code
+    // See Wago manual section 3.3
+    
+    // Check other status flags for clues
+    println!("Busy: {}", s2.has_flag(S2Flag::Busy));
+    println!("StandStill: {}", s2.has_flag(S2Flag::StandStill));
+}
+```
+
+**Common error codes:**
+- **2 blinks:** Overcurrent
+- **3 blinks:** Position error
+- **4 blinks:** Encoder fault
+- See Wago manual for complete list
+

+
+### Supporting Wago 750-671
+
+The 750-671 uses different C1 bit layout:
+
+1. **Create separate enum:**
+```rust
+// For 750-671
+pub enum C1Flag671 {
+    Enable         = 0b0000_0001,  // Bit 0
+    Stop2N         = 0b0000_0010,  // Bit 1
+    Start          = 0b0000_0100,  // Bit 2
+    MSpeedControl  = 0b0000_1000,  // Bit 3 (instead of command field)
+    MProgram       = 0b0001_0000,  // Bit 4
+    MReference     = 0b0010_0000,  // Bit 5
+    MJog           = 0b0100_0000,  // Bit 6
+    MDriveByMBX    = 0b1000_0000,  // Bit 7
+}
+```
+
+---
+
+## Quick Reference Card
+
+### Initialization Checklist
+```rust
+// 1. Create and configure
+let stepper = StepperVelocityWago750672::new(device);
+
+// 2. Set prescalers (optional, before enable)
+stepper.set_freq_range_sel(1);   // 0-3
+stepper.set_acc_range_sel(1);    // 0-3
+
+// 3. Set non-zero acceleration (REQUIRED)
+stepper.set_acceleration(10000);
+
+// 4. Enable
+stepper.set_enabled(true);
+
+// 5. Set velocity (after initialized)
+stepper.set_velocity(15000);     // ±25000 max
+```
+
+### Key Constants
+```rust
+const SPEED_CONTROL_CMD: u8 = 0x18;  // C1 command for 750-672
+const MAX_VELOCITY: i16 = 25000;
+const MIN_VELOCITY: i16 = -25000;
+const DEFAULT_ACCELERATION: u16 = 10000;
+```
+
+### Critical Rules
+1. ⚠️ **Never enable with zero acceleration**
+2. ⚠️ **Always wait for acknowledgments**
+3. ⚠️ **Issue Start pulse for every velocity change**
+4. ⚠️ **Prescalers can only be changed when disabled**
+5. ⚠️ **Keep Enable and Stop2_N high during operation**
+
+### Common Bit Patterns
+```rust
+// Enable + Stop2_N
+0b0000_0011
+
+// Enable + Stop2_N + Speed Control
+0b0001_1011
+
+// Enable + Stop2_N + Speed Control + Start
+0b0001_1111
+```
+
+### Debug Commands
+```bash
+# View byte values
+println!("C1: {:#010b}", dev.rxpdo.c1);
+println!("S1: {:#010b}", dev.txpdo.s1);
+
+# Check specific flags
+let s2 = StatusByteS2::from_bits(dev.txpdo.s2);
+println!("Error: {}", s2.has_flag(S2Flag::Error));
+println!("OnSpeed: {}", s2.has_flag(S2Flag::OnSpeed));
+
+# Monitor state
+println!("State: {:?}", dev.state);
+println!("Initialized: {}", dev.initialized);
+```
