Under Voltage Fault Behavior

You can adjust the conditions for an under voltage fault using VBUS.UVMODE in the WorkBench Terminal on pg. 1 View:

VBUS.UVMODE = 1 (default)

The drive will not report an under voltage fault unless the drive is enabled and VBUS.VALUE falls below VBUS.UVFTHRESH

VBUS.UVMODE = 0

The drive will report an under voltage condition any time VBUS.VALUE falls below VBUS.UVFTHRESH.

When an under voltage fault occurs, the drive is disabled and issues the following alerts:

WorkBench alert: 502 Bus Under Voltage
DriveControl device for regulating the speed, torque and position of a motor LED alert: Left LED displays [F], right LED displays [u-V].\
Fault relay output turns on.
