15: Fast Stop (N.O.)

Setting Value	Function	Description
15	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.
