C1-09
(0208)
Fast Stop Time
Sets the length of time that the drive will decelerate to zero for a
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.
• 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.
