Default
(Range)
C1-01
(0200)
RUN
Acceleration Time 1
Sets the length of time to accelerate from zero to maximum output frequency.
30.0 s

■
C1-09: Fast Stop Time
No.
(Hex.)
Name
Description
Default
(Range)
C1-09
(0208)
RUN
Fast Stop Time
Sets the length of time that the drive will decelerate to zero for a Fast Stop.
10.0 s
(0.1 - 6000.0 s)
These conditions will start the Fast Stop function:
•
When the drive received the Fast Stop command from the MFDI terminal
•
When you set
Fast Stop (Use C1-09)
for a parameter to set a stopping method when the drive detected a fault
Set
H1-xx = 15, 17 [MFDI Function Selection = Fast Stop (N.O.), Fast Stop (N.C.)]
.
When the drive receives the Fast Stop command, the motor ramps to stop in the deceleration time set in
C1-09
. After
the drive receives the Fast Stop command, you cannot start the drive operation again until deceleration is complete.
To clear the Fast Stop condition, deactivate the Fast Stop command, deactivate the Run command, then activate the
Run command again.
The terminal set for
H2-xx = 4C [MFDO Function Selection = During Fast Stop]
will activate during Fast Stop.
Note:
If you decelerate the drive too quickly, the drive will detect an
ov [Overvoltage]
fault and shut off the output, and the motor will coast to
stop. To prevent motor coasting and stop the motor quickly and safely, make sure to set a Fast Stop time in
C1-09
.
◆
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.
The following figure explains how S-curves are applied.
