Fast Stop (N.O.)
|
    
Sets the command to ramp to stop in the deceleration time set in C1-09 [Fast Stop Time] when the input terminal is ON while the drive is operating.

| Warning |
|
Incorrect Operation
Yaskawa recommends that you use H1-xx = 17 [Fast Stop (N.C.)].
If a circuit error occurs in the MFDI, the drive cannot stop the output when the terminal set to H1-xx = 15 [Fast Stop (N.O.)] turns ON.
|
If you cancel the fast stop input, the drive will not restart the motor until you meet these conditions:
Note:
-
To use the N.C. switch to input the fast stop command, set H1-xx = 17 [Fast Stop (N.C.)].
-
Refer to C1-09: Fast Stop Time for more information.
-
Set C1-09 [Fast Stop Time] to a correct deceleration time. If the deceleration time is too short, it can cause an overvoltage fault, which will not stop the motor from coasting.
