C1-09
(0208)
RUN
Fast Stop Ramp
Sets the ramp that the drive will decelerate to zero for Emergency 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 Tuning.
