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 times 1 are 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
Table i.34
.

Switching Acceleration and Deceleration Times by Motor Selection
When switching between motor 1 and 2 using a digital input (H1-
oo
= 16), parameters C1-01 to C1-04 become accel/decel
times 1 and 2 for motor 1, while C1-05 to C1-08 become accel/decel times 1 and 2 for motor 2. Accel/decel times 1 and 2 can
be switched for each motor using a digital inputs set to H1-
oo
= 7 like shown in
Table i.35
.
Note:
1.
The motor 2 selection function cannot be used with PM motors.
2.
Attempting to use the digital input setting “Accel/Decel time 2 selection” (H1-
oo
= 1A) together with motor 1/2 switching triggers an
oPE03 error, indicating contradictory multifunction input settings.
