Switching Acceleration and Deceleration Times by Motor Selection
When switching between motor 1 and 2 using a contact input (H1-
= 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 contact inputs set to H1-
= 7 like shown in
.
Note:
Attempting to use the contact input setting “Accel/Decel time 2 selection” (H1-
= 1A) together with motor 1/2 switching
triggers an oPE03 error, indicating a contradictory multifunction input settings.
Table 2.14 Motor Switching and Accel/Decel Time Combinations
Switching Accel/Decel Times by a Frequency Level
The drive can switch between different acceleration and deceleration times automatically. The drive will switch from
accel/decel time 4 in C1-07 and C1-08 to the default accel/decel time in C1-01 and C1-02 (C1-05 and C1-06 for motor 2)
when the output frequency exceeds the frequency level set in parameter C1-11. When the frequency falls below this
level, the accel/decel times are switched back.
shows an operation example.
Note:
Acceleration and deceleration times selected by contact inputs have priority over the automatic switching by the frequency level
set to C1-11. For example, if accel/decel time 2 is selected, the drive will use this time only and not switch from accel/decel time
4 to the selected one.

C1-11: Accel/Decel Time Switching Frequency
Sets the frequency at which the drive switches between accel/decel time settings.
Refer to Switching Accel/Decel Times
by a Frequency Level on page 129
for details.
Note:
Setting C1-11 to 0.0 Hz (0.0%) disables this function.
