MX2 Speed Control

5 posts in this topic

Hello I would like to control the Stop and Start via the Terminals so A001 and A002 are set to 01 but would like to control the speed reference using a NS HMI controlled via Modbus. Does anyone know if this is possible. In the manual it seems to imply that either control is by Terminal or Modbus but does not mention Separate control Many Thanks

Yes, it is possible to control the speed of MX2 inverter via Modbus interface. A001 register is responsible for the frequency source configuration and A002 for run command source configuration. You have to simply change the A001 register to 003 and leave A001 unchanged, this way you will control the speed via Modbus and apply RUN command via terminal block. Edited by Eradicated
