I recommend to use the FC14 as per the link bellow to control MM$ via profibus. Please feedback us if there are any other problems.

EIC_CONTROL Posts: 198 Rating: (36)	Hi My advise regarding this issue if you have MM440 parameters Document then first 1) reset your mm440 drive as factory default setting. 2)Then inter the documented parameters.

You have not explained your application, whether it is a winder or any other application. Some of the possible reasons are : a) Off / Disable command to the drive from PLC ( Can be easily check on the drive if this Is happening ) b) Incorrect setpoint to drive or insufficient setpoint c) Profibus communication disrupted ( Drive should give an Alarm/Fault in this condition ) d) Incorrect parameterisation. Hope this helps Cheers Navnag
