12.7 H: TERMINALS
578 SIEPCYEUOQ2V01A Q2V Technical Manual
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 491.
• 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 Description
3E SCBraking NO
Sets operation of Short Circuit Braking (N.O.).
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 454" for more information.
ON : Short Circuit Braking is enabled.
OFF : Normal operation
■ 3F: SCBraking NC
Setting Value Function Description
3F SCBraking NC
Sets operation of Short Circuit Braking (N.C.).
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 454" for more information.
ON : Normal operation
OFF : Short Circuit Braking is enabled.
■ 40: KEB Thru1 NC
Setting Value Function Description
40 KEB Thru1 NC
Sets operation of the KEB1 function through the KEB Ride-Thru 1 (N.C.).
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].
• Refer to "KEB Ride-Thru Function on page 637" for more information.
