RUN

Fast Stop Time

Sets the length of time that the drive will decelerate to zero for a Fast Stop.

10.0 s

(0.0 - 6000.0 s)
Note:

  • When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)], the setting range is 0.00 to 600.00 s.

  • When L2-29 = 0 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 1] and you do KEB Auto-Tuning, the drive will automatically set C1-09. If you must not change the Fast Stop time, do not do KEB Auto-Tuning.

The Fast Stop function will be triggered in the following circumstances.

  • The Fast Stop operation will be triggered by the input of the Fast Stop command via the multi-function digital input terminal.

  • The Fast Stop operation is will be triggered when by the input of the Fast Stop command is input via the multi-function digital input terminal.

Set H1-xx = 15, 17 [MFDI Function Select = Fast Stop (N.O.), Fast Stop (N.C.)].

When the Fast Stop command is input, the Fast Stop operation will be triggered at the deceleration time set to C1-09. The drive cannot be restarted after initiating a Fast Stop operation until deceleration is complete. Complete deceleration and cycle the Run command to clear the Fast Stop input.

The terminal set for H2-xx = 4C [MFDO Function Select = During Fast Stop] will be ON during Fast Stop.

Note:

Decelerating too quickly can cause an ov [Overvoltage] fault that shuts off the drive while the motor to coasts to a stop. Set a Fast Stop time in C1-09 that prevents motor coasting and makes sure that the motor stops quickly and safely.
