C1-08: Deceleration Time 4
No.
(Hex.)
Name Description
Default
(Range)
C1-08
(0207)
RUN
Deceleration Time 4
Sets the length of time to decelerate from maximum output frequency to zero.
10.0 s
(0.0 - 6000.0 s)
Note:
When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)] , the setting range is 0.00 to 600.00 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.
2.0 s
(0.0 - 6000.0 s)
Note:
• If C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)] , the setting range becomes 0.00 s to 600.00 s.
The Fast Stop function will be triggered in the following circumstances.
• The Fast Stop operation will be triggered by the input of the Fast Stop command via MFDI terminal.
• The Fast Stop operation is will be triggered when by the input of the Fast Stop command is input via MFDI
terminal.
Set H1-xx = 15, 17 [MFDI Function Selection = Fast Stop (N.O.), Fast Stop (N.C.)] .
When the Fast Stop command is input, the Fast Stop operation will be triggered at the deceleration time set to
C1-
09 . The drive cannot be restarted after initiating a Fast Stop operation until deceleration is complete. Complete
deceleration and cycle the Run command to clear the Fast Stop input.
The terminal set for
H2-xx = 4C [MFDO Function Selection = During Fast Stop]
will be ON during Fast Stop.
Note:
Decelerating too quickly can cause an ov [Overvoltage] fault. When ov is detected, the drive output will shut off and the motor will
coast to stop. Set a Fast Stop time in C1-09 that prevents motor coasting and makes sure that the motor stops quickly and safely.
■
C1-10: Accel/Decel Time Setting Units
No.
(Hex.)
Name Description
Default
(Range)
C1-10
(0209)
Accel/Decel Time Setting
Units
Sets the setting units for C1-01 to C1-08 [Accel/Decel Times 1 to 4] and C1-09 [Fast Stop Time] .
1
(0, 1)
0 : 0.01 s (0.00 to 600.00 s)
Sets acceleration and deceleration times in 0.01 s units. The setting range is 0.00 s to 600.00 s.
If
C1-01 to C1-08 [Accel/Decel Times 1 to 4] or C1-09 [Fast Stop Time] are set to 1000.0 s or longer, you cannot
set C1-10 = 0 . When one of those parameters is set to a value between 600.1 s and 1000.0 s, you can set C1-10 =
0
, but the time will change to 600.00 s.
1 : 0.1 s (0.0 to 6000.0 s)
The acceleration and deceleration times are set in 0.1 s units. The setting range is 0.0 s to 6000.0 s.
■
C1-11: Accel/Decel Time Switchover Freq
No.
(Hex.)
Name Description
Default
(Range)
C1-11
(020A)
Accel/Decel Time
Switchover Freq
Sets the frequency at which the drive will automatically change acceleration and deceleration
times.
Determined by A1-02
(0.0 - 590.0 Hz)
The acceleration and deceleration times for the drive are switched automatically when output frequency reaches
the setting value set to C1-11 . Setting C1-11 = 0.0 Hz (0.0%) disables this function.
