As long as the master does not receive a switch-on command, the slaves stay in oper-
ating state o10.0 (wait for switch-on from the master).
If the master receives a switch-on command, then it automatically transfers this to the
slaves. Then, all devices carry out their switch-on sequence, i.e. they attempt to go
into operating state o0. However, the master waits in operating state o1.7 until all
slaves have reached operating state o0 (exception: n+m operation for a 6-pulse paral-
lel connection)
If a slave leaves operating state o0, then the master outputs fault message F60044
(exception: n+m operation for a 6-pulse parallel connection)
• The speed setpoint and the actual speed value should be entered at the master
converter.
• The optimization runs should be started at the master converter. The slave converters
must be connected and ready for operation at this point.
