0.1~6000.0 s
Acceleration time is the time required to accelerate from 0 to 100% of maximum output frequency.
Deceleration time is the time required to decelerate from 100 to 0% of maximum output frequency.
Motor 1: Maximum frequency is set by parameter 01-02 and Motor 2 Maximum frequency is set by parameter
01-16.
Note: Actual acceleration and deceleration times can be affected by the inverter driven load.
The default values for the acceleration, deceleration times are dependent on the inverter size.
