C1: Accel and Decel Times

Four different sets of acceleration and deceleration times can be set in this product. Acceleration and deceleration
times can be switched during run when switching H1-xx = 7, 16, 1A [MFDI Function Select = Accel/Decel Time
Selection 1, Motor 2 Selection, Accel/Decel Time Selection 2] ON and OFF.
Acceleration time parameters always set the time to accelerate from 0 Hz to E1-04 [Maximum Output Frequency].
Deceleration time parameters always set the time to decelerate from E1-04 to 0 Hz.
C1-01 [Acceleration Time 1] and C1-02 [Deceleration Time 1] are the default active accel/decel settings.
Parameters
C1-01 [Acceleration Time 1]
C1-02 [Deceleration Time 1]
C1-03 [Acceleration Time 2]
C1-04 [Deceleration Time 2]
C1-05 [Acceleration Time 3]
C1-06 [Deceleration Time 3]
C1-07 [Acceleration Time 4]
C1-08 [Deceleration Time 4]
Note:
The setting range for acceleration and deceleration times is 0.00 to 600.00 s when C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s
(0.00 to 600.00 s)].

The following figure shows an operation example for changing acceleration and deceleration times. The example
below requires that the stopping method be set for b1-03 = 0 [Stopping Method Selection = Ramp to Stop].
