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 = 1 [KEB Method = Single KEB1 Ride-Thru] 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.
