AXIS#.VL.THRESH

Description

AXIS#.VL.THRESH sets the user overspeed fault threshold. This threshold becomes the overall overspeed fault threshold (AXIS#.VL.VFTHRESH) if it is less than the motor speed threshold (1.2 x AXIS#.MOTOR.VMAX), and for AXIS#.MOTOR.TYPE = 6 if it is less than the motor back EMF overspeed threshold ((1.02 x 1000 x VBUS.OVFTHRESH) / (AXIS#.MOTOR.KE x sqrt(2))).

The value is considered an absolute value, hence it applies for both negative and positive velocities.

Example

AXIS#.VL.THRESH is set to 600 rpm. A velocity (AXIS#.VL.FB ) of 700 rpm will generate an over speed fault.
