The drive can use output frequency to automatically switch between different acceleration and deceleration times. When the output frequency = C1-11 [Accel/Decel Time Switchover Freq], the drive automatically switches the acceleration and deceleration times. Set C1-11 = 0.0 Hz to disable this function.

Note:

  • The acceleration and deceleration times set to MFDIs take higher priority than the automatic switch that uses the frequency level set in C1-11. For example, if you set the switchover frequency to C1-11, the drive will not automatically switch acceleration and deceleration times when H1-xx = 7 [Accel/Decel Time Selection 1] is activated.

  • If Motor 2 Selection [H1-xx = 16] is activated, the drive will set the acceleration/deceleration time to C1-05 and C1-06 for motor 2 when the output frequency is more than the frequency level set in C1-11.
