Power supply 
voltage
- Not available at power modules
This monitoring function checks if the power supply voltage has a value within the adjust-
ed voltage range.
Phase monitoring - not available at power modules
This monitoring function checks the three phases of the power supply voltage.
If one phase is missing, the warning "Phase failure" is reported after at most 5 s. The mo-
tor can be supplied with nominal current for a limited time (refer to P130.24) or with phase
failure error current (refer to P129.25) unlimited.
If all phases are missing the error "Power supply failure" is generated after at most 5 s.
Ground fault This monitoring function checks if there is a short-circuit between the motor terminals and
the ground. If a short-circuit is detected, there is immediately a pulse inhibit.
Overcurrent This monitoring function checks if the motor current is greater than 1.3 times output peak
current. It serves as „Disaster prevention“ in case of an output-sided short-circuit.
DC link This monitoring function checks the voltage of the DC link. In case the voltage is below a
value, which was internally specified, the warning DC link undervoltage is generated by
the controller. In case the voltage exceeds an adjusted value (about 820 V), the error „DC
link overvoltage“ is signaled by the controller and the pulses are inhibited immediately.
Overload
monitoring
This monitoring function controls the present load whether the power unit can supply the
peak current at the moment. In case the peak current is not possible, the message „Power
unit monitoring active and max. torque current is limited“ (warning 206) is generated.
Temperature
device
internal space
This monitoring function checks the temperature in the internal space of the device.
m In case the temperature is higher than the warning threshold, the controller generates
a warning.
m In case the temperature is too high, the pulses are inhibited immediately.
Temperature
heat sink
This monitoring function checks the temperature of the heat sink.
m In case the temperature is higher than the warning threshold, the controller generates
a warning.
m In case the temperature is too high, the pulses are inhibited immediately.
NOTE
If you work without a mains filter a power supply failure or phase failure is recognized
after 100 ms. If the device is operated with a mains filter the power supply failure or
phase failure can be detected after about 5 s. According to load state the failure can
also be detected considerably earlier.
