So 6RA70?
I’m curious, P141 is encoder ppr. Why change that from plc?

Are you sending the speed demand in the PZD data?
I alteady send speed reference in pzd but in some cases i need to refine it by slowing or rapidly the motor some bit for example if final linear speed is 35m/min i refine it to 34.8 by changing p141 for example from 1000 to 990

If you have spare capacity in the PZD area you could change the scaling - see the speed setpoint system block diagram:
i am not familar with your drive but please be aware thatt most drives store parameters in a ROM memory area which can only be writen a limited number of times before the ROM fails ( typically 700 to 1500 times ) . Please check if you can store this parameter in the RAM memory without downloading to ROM .
