Monitoring functions of the power part on the motor side
y
Overcurrent (motor) monitoring function
Each of the three motor phase currents is monitored.
If the phase current exceeds 30% of the peak value of the permissible peak current, the BUM 62 T
generates a message. This message is stored in the BUM 62 T and transmitted to the controller. The
message ”Power stage on the motor side ready” is cleared.
y
Earth current (short-circuit) monitoring function
The earth fault current of the motor phases is monitored.
A message is generated when the fault current exceeds 20 % of the peak value of the permissible
peak current of the power part. An earth fault at the motor connection is very probable. This message
is transmitted to the controller. The message ”Power part on the motor side ready” is cleared.
y
Overvoltage DC link monitoring function
The voltage of the DC link is monitored.
If the DC link voltage exceeds 800 V, a message is generated. This message is transmitted to the
controller. The message ”Power stage on the motor side ready” is cleared.
y
Power transistors monitoring function
The collector-emitter saturation voltage is monitored.
If the voltage is too high, an overcurrent is applied to the power transistor, caused e.g. by a short-
circuit of the motor terminals and a controlled switch-off procedure switches off the transistor and
generates a message. This message is transmitted to the controller. The message ”Power stage on
the motor side ready” is cleared.
NOTE
The overcurrent message and the subsequent stop of the drive protects the drive from damage/
destruction. To avoid the message Overcurrent (motor), you must limit the permissible peak
current of the motor phase currents by the control.
NOTE
The DC link voltage can rise until it is switched off if the drive brakes and no or an insufficient
regenerative circuit is connected to the DC link.
NOTE
To ensure a recovery of the transistor after a switch-off because of overcurrent, the message can
only be reset after at least 5 seconds (typically 10 s).
