7C: Short Circuit Braking (N.O.)

Setting Value	Function	Description
7C	Short Circuit Braking (N.O.)	Sets operation of Short Circuit Braking (N.O.).

Warning

Incorrect Operation

Yaskawa recommends that you use H1-xx = 7D [Short Circuit Braking (N.C.)].

If a circuit error occurs in the MFDI, the motor can take longer than expected to stop when the terminal set to H1-xx = 7C [Short Circuit Braking (N.O.)] turns ON.

The drive will short circuit the three phases of a PM motor to cause braking torque in the spinning motor.

Note:

When A1-02 = 8 [Control Method Selection = EZOLV], this function is available only when you use a PM motor.
Refer to b2: DC Injection Braking and Short Circuit Braking for more information.

ON
Short Circuit Braking is enabled.
OFF
Normal operation
