# Mitsubishi Inverter settings for Modbus RTU
# Inverter settings
Protocol Selection: set Pr 549 to 1 (Modbus RTU)
set 551 to a non zero value (9999)
Operation mode selection: set Pr 79 to 0
PU communication station number: set Pr 117 to a value of 1-32 (this is also the slave address)
PU communication speed: set Pr 118 the same baudrate as the Beckhoff terminal. For example Terminal has 19200 then you need to set 192
PU communication stop bit: set Pr 119 according to Beckhoff terminal setting
PU communication parity check: set Pr 120 according to Beckhoff terminal setting

# Inverter settings relevant for Motor
## Motor Constant
The following is a table that shows which Registers need to be set for the safe operation of the Motor.
The following is a table that shows which Registers need to be set on the Inverter for the safe operation of the Motor.
| Parameter number (Pr) | Name | Value |
| --------------------- | ---------------------------- | ------------- |
| 71 | Applied Motor | 0 |
| 80 | Motor Capacity | 15 (1.5 kw) |
| 96 | Auto tuning setting/status | 1 |
| 1 | Max Frequency | 5000 |
| 2 | Min Frequency | 0 |
| 9 | Electronic Thermal O/L Relay | 3.30 (Ampere) |
| 3 | Base frequency | 5000 (50 Hz) |
| 19 | Base frequency voltage | 400 (Volt) |
| `71` | Applied Motor | 0 |
| `80` | Motor Capacity | 15 (1.5 kw) |
| `96` | Auto tuning setting/status | 1 |
| `1` | Max Frequency | 5000 |
| `2` | Min Frequency | 0 |

## Settings relevant for Communication/Control
## All Settings needed for the Inverter Communication/Operation with Extruder
| Parameter number (Pr) | Name | Value |
| --------------------- | ------------------------------------ | ----- |
| 79 | Operation Mode | 0 |
| 340 | Communication startup mode selection | 1 |
The Combination of 79 = 0 and 340 = 1 starts the inverter in the NET operation Mode, which enables us to start/stop the motor.
The Following settings are required to get the inverter Communication and Operation working properly
| Parameter Number (Pr) | Value | Description |
| --------------------- | ----- | -------------------------------------------------------------------------------------------- |
| `Pr. 78` | 0 | Allows Reverse Rotation |
| `Pr. 79` | 0 | Operation Mode Selection |
| `Pr. 117` | 1 | Station Number (Slave Number) |
| `Pr. 118` | 192 | Baudrate (192 → 19200 bps) |
| `Pr. 119` | 0 | Stop Bit Length |
| `Pr. 120` | 2 | Parity Check |
| `Pr. 121` | 9999 | PU communication retry count |
| `Pr. 122` | 1.0 | Communication Check Time (Time until no communication causes E.PUE fault), 0.1 seconds steps |
| `Pr. 338` | 0 | Communication operation command source, 0 -> given through PU |
| `Pr. 339` | 0 | Communication speed command source, 0 -> given through PU |
| `Pr. 340` | 1 | Startup in Network Mode |
| `Pr. 549` | 1 | Protocol Selection (1 = Modbus) |
| `Pr. 551` | 9999 | Automatically Detect PU Connector |
