Thepurposeofthisfunctionistomakesurethedrivegeneratessufcienttorquetosupporttheloadofcranes
orotherhoistingequipment,duringthebrakereleasetransientphase.
Enable Torque pr Enablesthemechanicalbrakecontrolfunction.Itisusedtoapplyatorquecapableof
sustainingaloadduringthetransientphaseofreleasing/openingthebrake.
Closing speed Aftersendingastopcommandtothedrive,thisisthespeedofthemotorforwhichthe
brakeisclosed.
Torque delay Thedelay,afterastartcommand,withinwhichthebrakeopeningtransientphasemust
becompletedsothatthe“BrakeFault”alarmisnotenabled.
Torque proving Thevalueofthecurrentcapableofsustainingtheloadbeforethebrakeisreleased
(percentageofFLC).ThiscanbesetviaparameteroranaloginputsetasBrake Ref
(32).
Actuator delay Thetimefromwhenanopenbrakecommandissentuntilthereferenceisactive.
