C1-09: Fast Stop Time
Sets a special deceleration used when a select group of faults occur or when closing a contact input configured as
H1-
= 15 (N.O. input) or 17 (N.C. input). A momentary closure will trigger the Fast Stop operation; it does not have
to be closed continuously. Unlike standard deceleration, when the Fast Stop operation is initiated, the drive cannot be
restarted until the deceleration is complete, the Fast Stop input is cleared, and the Run command is re-input.
A contact output programmed for “During Fast Stop” (H2-
= 4C) will be closed as long as Fast Stop is active.
A Fast Stop can be selected as the action the drive should take when certain faults occur, such as L8-03 (Overheat
Pre-Alarm Operation Selection).
Note:
Rapid deceleration can trigger an overvoltage fault. The drive output shuts off when faulted and the motor coasts. Set an
appropriate Fast Stop time to C1-09 to avoid this uncontrolled motor state and to ensure that the motor stops quickly and safely.
n
C1-10 Accel/Decel Time Setting Units
Determines the units for the acceleration and deceleration times set to C1-01 through C1-09 using parameter C1-10.
Setting 0: 0.01 s units
The accel/decel times are set in 0.01 s units. The setting range will be 0.00 to 600.00 s. C1-10 cannot be set to 0 if any of
the parameters C1-01 to C1-09 are set to 600.1 s or more.
Setting 1: 0.1 s units
The accel/decel times are set in 0.1 s units. The setting range will be 0.0 to 6000.0 s.
u
C2: S-Curve Characteristics
Use S-curve characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load. Set
S-curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.
n
C2-01 to C2-04: S-Curve Characteristics
C2-01 through C2-04 set separate S-curves for each section of the acceleration or deceleration.
No.

Fast Stop Time
<1> The setting range for the acceleration and deceleration times is determined by the acceleration/deceleration time setting units in C1-10. For
example, if the time is set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
