10.2.3 Monitoring function - explanations BM53XX
Ground fault
This monitoring function checks whether there is a short circuit between at least one mo-
tor terminal and ground. If a short circuit is detected, pulses are inhibited immediately.
Overcurrent
This monitoring function checks whether the motor current or the mains current is larger
than 1.3 times of the peak output current. This monitoring function provides a „disaster
prevention“ in case of a short circuit of the output side.
DC link
This monitoring function checks the voltage in the DC link. If the voltage drops below an
internally set value (approx. 210 V), the controller reports „DC link undervoltage“ and a
warning is signaled. If the voltage rises above an internally set value (approx. 835 V), the
controller reports the error „DC link overvoltage“ and pulses are inhibited immediately.
Overload
monitoring
This monitoring function checks 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.
Internal tempera-
ture of device
This monitoring function checks the temperature in the interior of the device.
m
If the temperature is higher than the warning threshold, then the controller signals a
warning.
m
If the temperature is higher than the maximum allowable device interior temperature,
then the pulses are inhibited immediately.
Heat sink
temperature
This monitoring function checks the temperature of the heat sink.
m
If the temperature is higher than the warning threshold, then the controller signals a
warning.
m
If the temperature is higher than the maximum allowable heat sink temperature, then
the pulses are inhibited immediately.
Motor
temperature
This monitoring function checks the temperature of motor. If the I²t-threshold is exceeded,
then the error message „I²t overload“ is generated by the controller.
Only for
KTY84 and PT1000
sensor
If the set temperature threshold 1 is exceeded, then the warning „Temperature threshold
1 exceeded“ is generated by the controller.
If the set temperature threshold 2 is exceeded, then the warning „Temperature threshold
2 exceeded“ is generated by the controller.
If the temperature falls below the minimum measurable value, or if a short circuit occurs
at the sensor, then the error message „Temperature sensor short circuit“ is generated.
If the temperature is higher than the maximum measurable temperature, or if the sensor
is not connected, then the error message „Temperature sensor not connected“ is gener-
ated by the controller.
For all
sensors
The error message „Over temperature“ is generated by the controller and the pulses are
inhibited immediately if the threshold (type-specific) of the temperature switch or of the
sensor is exceeded.
Position
controller
This monitoring function checks the position deviation limit statically/dynamically. If the
current position deviation is statically/dynamically larger than the set position deviation
limit, then the error message „Static position deviation“ or „Dynamic position deviation“ is
generated. After the monitoring period (position deviation period) an additional error mes-
sage is generated and pulses are inhibited immediately. The reaction time can be set.
