ACS850 Reverse Run Command through Modbus communication?
I've tested the AC800M Controller with ACS850 drive through modbus communication. The drive is working fine with single mode of operation i.e. forward run.
But I didn't find any way to run the drive in reverse direction.
As in profibus communication the direction can be controlled by applying -ve (up to -20000) speed ref. But in modbus communication -ve ref can’t be written in the speed command register.
I've tried another method in which I assigned a reserved bit (15th bit) of control word to control the direction. Is it recommended?
Or is there any convenient method to do it?
