Switching Acceleration and Deceleration Times by Motor Selection
When switching between motor 1 and 2 using a contact input (H1-
decel time 1 and 2 for motor 1, while C1-05 to C1-08 become accel/decel time 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-
Note: 1. The motor 2 selection function cannot be used when PM motor is used.
2. The contact input setting "Accel/Decel time 2 selection" (H1-

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 it falls below this level, the accel/
decel times are switched back.
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.
