Issue:Controlling ATV312 in reverse direction with Profibus.
Product Line:ALTIVAR 312
Environment:All Serial numbers
Cause:N/A
Resolution :When controlling the ATV312 VIA profibus, profibus ignores the last 8 bits of the ATV312 Modbus Command word. Therefore, to command the VFD to run in the reverse direction, a negative speed reference must be written to the speed reference.
