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.
4.14.6.1
Behavior when undervoltage condition is present
The behavior in an undervoltage condition depends on the VBUS.UVMODE setting.
VBUS.UVMODE
DC Bus Undervoltage Mode. Consult the
Workbench Online Help
for
configuring the parameter.
0
The drive will report a F502 undervoltage fault any time an
undervoltage condition occurs.
1 (default)
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.
