■ 3E: SCBraking NO
Setting Function Description
3E SCBraking NO
Sets operation of Short Circuit Braking (N.O.).
If a three-phase PM motor short circuits, the drive will generate braking torque in the spinning motor. This will
stop motor rotation and also prevent external forces from spinning the motor.
Note:
• When A1-02 = 8 [Control Method = EZ Vector], this function is available if you use a PM motor.
• Refer to “b2: DC INJ / SHORT CKT BRAKE” for more information.
ON : Short Circuit Braking is enabled.
OFF : Normal operation
■ 3F: SCBraking NC
Setting Function Description
3F SCBraking NC
Sets operation of Short Circuit Braking (N.C.).
If a three-phase PM motor short circuits, the drive will generate braking torque in the spinning motor. This will
stop motor rotation and also prevent external forces from spinning the motor.
Note:
• When A1-02 = 8 [Control Method = EZ Vector], this function is available if you use a PM motor.
• Refer to “b2: DC INJ / SHORT CKT BRAKE” for more information.
ON : Normal operation
OFF : Short Circuit Braking is enabled.
■ 40: KEB Thru1 NC
Setting 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” for more information.
■ 41: KEB Thru1 NO
Setting Function Description
41 KEB Thru1 NO
Sets operation of the KEB1 function through the KEB Ride-Thru 1 (N.O.).
