10.2.2 Monitoring function - explanations BM51XX
Power supply
voltage
The BM51XX provides 2 settable thresholds to check the power supply voltage. The ac-
tive mains rectifier generates a message if the power supply voltage is above/below the
set thresholds. This message is generated as warning by default, the reaction can be
changed to pulse inhibit.
The device generates an error message and a shutdown follows if the mains voltage is in
operation out of the permitted range (refer to
Requirements for power supply / mains
Phase monitoring
This monitoring function checks the voltage of the three power supply phases. The error
„Phase failure“ is generated if one phase is missing. The error „Power supply failure“ is
generated, if 2 or 3 phases are missing. The active mains rectifier generates a warning
first and disables then the active operation with the error message „Power supply syn-
chronization lost“ if the power supply frequency exceeds the permitted range. The active
mains rectifier changes to error state generating the message „Power supply synchroni-
zation not possible“ if a synchronization to the power supply is not possible before starting
active operation.
Charging
This monitoring function checks the charging of the DC link voltage. The error „Timeout
DC link“ is generated if the DC link voltage cannot be charged to power supply maximum
voltage within 10 s. The active mains rectifier stops the operation with the error message
„Short circuit at DC link“ if the DC link voltage does not rise as expected while charging.
Discharging
The device is not separated from the power supply successfully if a mains current is de-
tected while discharging. The discharge resistor would be connected directly to the power
supply therefore the error „Power supply current during discharging“ is generated.
If the DC link voltage can not be discharged within approx. 10 s, the error „Time-out quick
discharge“ is generated.
DC link
This monitoring function checks the voltage at the DC link. If the voltage is lower than an
internally set value (approx. 80 V under the specified value or 87 % of the power supply
peak value), the controller generates the error „DC link undervoltage“. If the voltage rises
above an internally set value (approx. 835 V), the controller generates the error „DC link
overvoltage“ and pulses are inhibited immediately.
The user set value is too low ensuring an adequate dynamic controlling if the set U
DC link
set value at the moment is lower than a threshold 40 V above the power supply peak val-
ue. In this case the error „Undervoltage U
DC link
“ is generated.
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.
