5.3 C: Tuning
C parameters control various aspects of how the drive accelerates and decelerates the motor. This includes S-curve, slip compensation, torque compensation
and carrier frequency.

C1-01 to C1-08: Accel/Decel Times 1 to 4
C1-01 (Acceleration Time 1) sets the time to accelerate from 0 to the maximum output frequency (E1-04). C1-02 (Deceleration Time 1) sets the time to
decelerate from maximum output frequency to 0. C1-01 and C1-02 are the default active accel/decel settings.
No. Parameter Name Setting Range Default
C1-01 Acceleration Time 1
0.0 to 6000.0* 10.0 s
C1-02 Deceleration Time 1
C1-03 Acceleration Time 2
C1-04 Deceleration Time 2
C1-05 Acceleration Time 3 (Motor 2 Accel Time 1)
C1-06 Deceleration Time 3 (Motor 2 Decel Time 1)
C1-07 Acceleration Time 4 (Motor 2 Accel Time 2)
C1-08 Deceleration Time 4 (Motor 2 Accel Time 2)
*The setting range for the acceleration and deceleration times is determined by C1-10 (Accel/Decel Time Setting Units). 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.
Detailed Description
C1-01 and C1-02 are the factory default active accel/decel “pair”. Other accel/decel pairs (C1-03 to C1-08) exist that can be activated by a multi-function
digital input (H1-oo = 7 and 1A). Alternatively, the active accel/decel pair can be switched from accel/decel pair 1 (C1-01 and C1-02) to accel/decel
pair 4 (C1-07 and C1-08) by a switch over frequency as programmed in parameter C1-11.

C1-09: Fast Stop Time
A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a special deceleration that can be
operated by closing a digital input configured as H1-oo = 15 or H1-oo = 17. A digital input configured as H1-oo = 15 will look for a switch closure
before initiating the Fast Stop operation. A digital input configured as H1-oo = 17 will look for the switch opening before initiating the Fast Stop
operation.
No. Parameter Name Setting Range Default
C1-09 Fast Stop Time 0.0 to 6000.0* 10.0 s
*Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the drive cannot be re-operated until the deceleration is
complete, the Fast Stop input is cleared, and the run command is cycled.
