Note:
• To use the N.O. switch to input the fast stop command, set 34 [Fast Stop NO].
• For details, refer to
C1-09: Fast Stop Time on page
• Set C1-09 [Fast Stop Time] to a correct deceleration time. If the deceleration time is too short, it can cause an overvoltage fault and
failure to stop the motor from coasting.
Figure 12.71 shows an example of how fast stop operates.

3E: SCBraking NO
Setting Value Function
3E SCBraking NO
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 = EZ Vector], this function is available only when you use a PM motor.
• Refer to
"b2: DC INJ / SHORT CKT BRAKE on page
ON : Short Circuit Braking is enabled.
OFF : Normal operation
■
3F: SCBraking NC
Setting Value Function
3F SCBraking NC
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 = EZ Vector], this function is available only when you use a PM motor.
• Refer to
"b2: DC INJ / SHORT CKT BRAKE on page
ON : Normal operation
OFF : Short Circuit Braking is enabled.
■
40: KEB Thru1 NC
Setting Value Function
40 KEB Thru1 NC
ON : Normal operation
OFF : Deceleration during momentary power loss
When you enable KEB Ride-Thru 1, set L2-29 [KEB Method]. The drive operates with the selected KEB method.
Note:
• If you set KEB Ride-Thru 1 [H1-xx = 40, 41] and KEB Ride-Thru 2 [H1-xx = 42, 43] at the same time, the drive will detect oPE03
[Multi-Function Input Setting Err].
