Power unit

All the power unit related data are divided into two groups. The first group includes the
so-named power unit data which is shown in parameter group 129 and cannot be written
to.
The power unit has a non-volatile memory which holds the power unit data. When the
controller is initialized, these data are read out and transferred to the corresponding pa-
rameters in group 129.
The second group, parameter group 130, contains all the other power unit working data.
These parameters represent either constantly changing physical quantities or certain set-
tings which generally can be altered.
Detection of a mains failure
The detection of mains failure at external supply is possibly not fast enough for specific
applications. Therefore a mains failure detection is optionally possible via the DC link volt-
age (see Z130.35–).
Behavior at mains failure
The drive can be configured that operation is possible at a mains failure for a set time
(Z130.25–). Different kinds of behavior can be set (see Z130.10–):
– Disable only motor operation (generator operation is enabled, field current is further
supplied). This behavior is only possible at external supply.
– Normal operation (motor and generator operation): Normally this option makes only
sense at a DC link combination if another axis feeds back power to the DC link. This
behavior is only possible at external supply.
– Disabling and automatic restart: The pulses are inhibited in case of detected mains
failure. The drive changes to "Switch-on inhibit (1)" state and coasts down. If the time
of the mains failure is shorter than the set Mains failure delay (Z130.25–), the drive
restarts automatically. The drive changes automatically in the "Operation enabled"
state again.
