DC Inject Braking Time at Start

Sets the DC Injection Braking Time at stop. Sets the time of Zero Speed Control at start when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].

A1-02 = 4: 0.30 s

Other than A1-02 = 4: 0.00 s

(0.00 - 10.00 s)

This function stops then restarts a coasting motor and increases motor flux to make high starting torque (a process called initial excitation). Set this parameter to 0.00 to disable the function.

Note:
  • To restart a coasting motor, use DC Injection Braking to stop and then restart the motor, or enable Speed Search. Enable DC Injection Braking or Speed Search to prevent ov [Overvoltage] or oC [Overcurrent] faults.

  • Sets the time of Initial Excitation at start when A1-02 = 4 [AOLV] and n4-72 = 1 [Speed Feedback Mode = Without Encoder].
