Changing Velocity on the fly with MODBUS
I would like to know how to perform on the fly velocity(rpm) changes over Modbus. I thought I had the answer but it's not working as anticipated.
It is an AKD-P01206-NBAN-0000 purchased in the Sept 2017
I am in operation mode 1, Velocity and using Service motions. The SM.MODE is 2. I am using SM.V2 to change the speed and have set SM.T2 to 0 to enable continuous running.
The value of SM.V2 is changing but the drive only changes speed if I stop and start again (DRV.STOP, SM.MOV)
What would I have to change in my approach to enable changing speed over MODBUS on the fly. I am using a completely wrong method (service motions) ?
