(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern Parameters
5 - 240
5.8.2 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 out-
put frequency is changed linearly (linear acceleration/deceleration) to reach the set frequency with-
out straining the motor and inverter. Linear acceleration/deceleration has a uniform frequency/time
slope.
