Motor Velocity Limiting
The
motor_max_velocity
(1082) is set as one of the motor parameters, when a drive is configured for use with a
particular motor.
A linear de-rating of the torque applied to the motor is implemented when the velocity of the drive exceeds the
motor max velocity. The de-rating is such that the demand torque is applied when at the velocity limit, but that
torque is reduced to zero, when at 5% above the velocity limit. The de-rating gives a smoother profile, than
simply zeroing torque if the velocity limit is exceeded.
