Function

Description

17

Fast Stop (N.C.)

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.

If you cancel the fast stop input, the drive will not restart the motor until you meet these conditions:

  • Fully stop the motor

  • Cancel the Run command

  • Cancel the fast stop command

Note:

  • To use the N.O. switch to input the fast stop command, set 15 (Fast Stop (N.O.)).

  • 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 and failure to stop the motor from coasting.

Figure 1 shows an example of how fast stop operates.
