CFW300 VFD & HMIST6200

[marija2001]

Hi everyone,

I'm currently working on a simple application involving a CFW300 frequency drive and a Schneider Electric HMI (HMIST6200). I've successfully established Modbus RTU communication between the two devices, and most things are working as expected, I'm able to read parameters from the drive, including an analog input value and any other values without problem. The digital inputs (e.g., Start/Stop switches) are also being monitored correctly – their status shows up properly on the HMI and the communication is established. 

However, the issue I'm facing is with writing the Start command to the drive from the HMI. When I press the Start button on the HMI, the motor does not start. The signal appears to be sent (no communication error), but the drive does not respond by starting the motor.

Has anyone encountered a similar issue? Any tips or suggestions would be greatly appreciated!

Thanks in advance!

can you please share application?
also share the manual of the drive and see access level of the drive.
