Hello everyone,
Page 142 Communicating with the PLC 6.2 MODBUS communication Mapping table The SINAMICS V20 inverter supports two sets of registers (40001 to 40062, 40100 to 40522) as the table below shows. 'R', 'W', 'R/W' in the column Access stand for read, write, read/write. This is my first post on this forum and first application on modbus rtu, so please by patient. I have PLC s7-1200 and inverter sinamics v20. I can change value of inverter parameteres or read some value, but I don't know which commands shall I send from mapping table to run motor. Thank you for any response. 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. Modbus SINAMICS V20 SINAMICS V20 SINAMICS V20 Motor Braking module Resistor. 5 Easy to use Robustness SINAMICS V20 feature Your benefits Wider voltage range, better cooling design and coated PCB increase robustness of the drive in difficult environments. Operation possible when the line.
Sinamics V20 Parameter Setting
Sinamics V20 Modbus Register Card
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.
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'.
Sinamics V20 Modbus Register Of Deeds
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.
