Plug braking of motors in the event of a power failure
Check logic for proper functioning according to planning engineer’s data.
If a plug braking resistor is used, an auxiliary contact of the contactor must be
provided to ensure that the drive cannot be enabled unless the braking resis-
tor has been deactivated. The ”Plug brake enable delay” must be disabled
(=0) for this test.
The contactor is driven by output ”OUT4” of the inverter.
In order to avoid faults and overload, a relay must be connected in
series.
Holding brake
Check holding brake for proper functioning if the motor is equipped with a
holding brake.
The holding brake is released when 24VDC are connected.
The contactor is triggered by the ”OUT3” output of the inverter.
In order to avoid faults and overload, a relay must be connected in
series.
EMERGENCY-STOP circuit
Check for proper functioning according to planning engineer’s data.
Finish checking
Switch off all voltages.
If all checks were completed successfully, proceed to the next section.
Otherwise, all faults that have occurred must be eliminated.
