Switch-On and Switch-Off Behavior
This chapter describes the switch-on and switch-off behavior of the PSD.
4.14.6
Behavior of "holding brake" function
Drives with an enabled holding brake function have a special timing for switching on and off the
output stage (➜ # 118). Events that remove the DRV.ACTIVE signal trigger the holding brake to
apply. As with all electronic circuits, the general rule applies that there is a possibility of the internal
holding brake module failing.
Functional safety, e.g. with hanging load (vertical axes), requires an additional mechanical brake
which must be safely operated, for example by a safety control.
If velocity drops below threshold CS.VTHRESH or timeout occurs during a stop procedure, the brake
is applied. Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the motor holding
brake (➜ # 118) immediately after faults or Hardware Disable.

Behavior when undervoltage condition is present
The behavior in an undervoltage condition depends on the VBUS.UVMODE setting.

The drive will report a F502 undervoltage fault any time an
undervoltage condition occurs.
The drive will report a warning n502 if not enabled. The drive will
report a fault if the drive is enabled when the condition occurs, or an
attempt is made to enable while an under voltage condition occurs.
