5.3 C: Tuning
C parameters are used to set the acceleration and deceleration characteristics, as well as S-curves. Other parameters in this
group cover settings for slip compensation, torque compensation, and carrier frequency.
C1: Acceleration and Deceleration Times
u
C1-01 to C1-04: Accel, Decel Times 1 and 2
n
Two different sets of acceleration and deceleration times can be set in the drive by digital inputs, motor selection, or switched
automatically.
Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency (E1-04).
Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. C1-01 and C1-02
are the default active accel/decel settings.
No.

<1> The setting range for the acceleration and deceleration times is determined by the accel/decel 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.
Switching Acceleration Times by Digital Input
Accel/decel time 1 is active by default if no input is set. Activate accel/decel times 2, 3, and 4 by digital inputs
(H1-oo = 7 and 1A) as explained in
Accel/Decel Time Sel. 1
H1-oo = 7

Figure 5.23
shows an operation example for changing accel/decel times. The example below requires that the stopping method
be set for "Ramp to stop" (b1-03 = 0).
C1-09: Fast-stop Time
n
Parameter C1-09 will set a special deceleration that is used when certain faults occur or that can be operated by closing a
digital input configured as H1-oo = 15 (N.O. input) or H1-oo = 17 (N.C. input). The input does not have to be closed
continuously, even a momentary closure will trigger the Fast-stop operation.
Unlike standard deceleration, once 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 cycled.
A digital output programmed for "During Fast-stop" (H2-01/02/03 = 4C) will be closed as long as Fast-stop is active.
