VL.VFTHRESH

Description

This parameter reports the overall overspeed fault threshold. Whichever of the following thresholds has the smallest value is used as the overall overspeed fault threshold:

  • User overspeed threshold (VL.THRESH).
  • Motor mechanical overspeed threshold (1.2 x MOTOR.VMAX)
  • If MOTOR.TYPE = 6, the motor back EMF overspeed threshold ((1.02 x 1000 x VBUS.OVFTHRESH) / (MOTOR.KE x sqrt(2))).
