Greetings,

All these screenshots are ok, but we need additional explanation about your problem.
I guess you can not start your drive through Modbus RTU protocol right?

Did you try it also with Modscan or similar program?
Maybe your control system has some configuration error.

my problem is that i can not start the drive throught modbus even (47f) command is sent, you can see the CW on the EFB parameters (58.18) showing 47f, but the main control word (06.01) is showzing other value because of bit n 3

Hi Souag,

Just would like to know if you have solved the issue, as I have the same problem.
If you have solved it, could you tell me how to fix it?
Thank you.

Hi Mr. Mohammed,

Yes, you solved the problem?
I could run the drive by changing P58.15 to "ANY MESSAGE".
Yet, it still showed cw/ref loss in P58.7......

My problem was with main control word, actually you need to send first 1030(dec) to the drive then 1151(dec), then reference (0 to 20000)

Thank you for your advise.
I tried it, but P58.7 also showed cw/ref loss...
Am not sure if there is any bug with my drive.
