6. 8. 1 Obtaining large torque with DC braking
<F249: DC braking carrier frequency>
<F250: DC braking frequency>
<F251: DC braking amount>
<F252: DC braking time>
<F253: Fwd/Rev DC braking priority>
■ Function
Apply direct current to the motor to obtain braking torque. This will stop the motor. It is used, for
example, to securely decelerate and stop the motor.
You can set the amount and time of direct current applied to the motor and the start frequency.
