When we have a fault such as F60042 Defective tachometer monitoring error all drives fault as expected. The master drive however losses its "Master Status" ie r53311 = 0. When we give the drives a reset command via profibus the master status does not return to 1 for the master drive. For both the master and substitute master drive r53311 remains at 0. The only way we can get the master to have r53311 = 1 is to cycle the control power to the drive. Is there anyway we can get r53311 on the master drive to return to 1 after a fault by not cycling the control power? The starter configuration file is attached.
