When it is 0, there is no monitoring. from manual: *Inverter behaviour at "P2040=0"* If monitoring is switched off and the PROFIBUS Master system goes to the status Stop (e.g. S7 CPU), the inverter remains active with the last received target specifications (control word, frequency target value)!

If P0700 = 2, Check also P1000 and tell us the status of the DIN1, DIN2, DIN3,...of the drive. Also are you sure that the drive commands comes from the stopped S7-400? Waiting for your reply. Regards,
