Acceleration/deceleration pattern

The acceleration/deceleration pattern can be set according to the application.
In addition, the backlash measures that stop acceleration/deceleration by the frequency or time set with parameters at
acceleration/deceleration can be set.

Linear acceleration/deceleration (Pr.29 = "0" initial value)
• When the frequency is changed for acceleration, deceleration, etc. during inverter operation, the output frequency is
changed linearly (linear acceleration/deceleration) to reach the set frequency without straining the motor and inverter.
Linear acceleration/deceleration has a uniform frequency/time slope.
