Sinamics V20 Manual
- Oct 31, 2018 To setup the inverter in modbus mode i have followed the v20 example modbus document on page 13. (CN011 setting, just puts it into Modbus mode) Notice on the same document the first few pages show the control word STW. This is used to control/ turn the motor on and off. The register for this is shown on the other document (Inverter manual) if.

Hello everyone,
I'm trying to use an arduino Duamelinove to comunicate with a Sinamics V20 inverter via RS485. I have a shield to convert the RS232 from the arduino to the RS485 from the inverter. I also have a RS485/USB adapter to monitor the communication from a computer.
Motor Braking module Resistor SINAMICS V20SINAMICS V20 feature Your benefits The dynamic energy is dissipated as heat in a braking resistor with an adjustable duty cycle of between 5% and 100%. Possible to use dynamic braking to increase braking performance. Inverters ≥ 7.5 kW have an integrated braking module.
I've loaded the SimpleModbusMaster library example on the arduino, and I'm getting transmission errors on the computer monitor (values different from what was transmited). The inverter receives the signal, but it returns a 'parity error'.
I also tried communicating the inverter with the computer, without the arduino, using a Modbus Master demo and, this time, it returns a 'character structure error'.
Has anyone ever tryied to do something similiar before? I'm not sure if this is even possible as everything I find online mention only communication between Siemens Inverters with Siemens PLCs.
Any thoughts would be appreciated.
