Description
Selects the forced current vector rotation mode at low
speeds. When the smooth start mode is selected, the rate of
acceleration is limited by the acceleration and deceleration
ramp times (parameters
driven by the permanent magnet motor has high inertia,
slow ramp times are recommended.
Can be used for permanent magnet motors only.
Disabled
Enabled
Current used in the current vector rotation at low speeds.
Increase the smooth start current if the application requires
high pull-up torque. Decrease the smooth start current if
motor shaft swinging needs to be minimized. Note that
accurate torque control is not possible in the current vector
rotation mode.
Can be used for permanent magnet motors only.
