Acceleration and deceleration pattern (Pr. 29)
You can set the acceleration/deceleration pattern suitable for application.
The above parameter can be set when Pr. 160 = 0.
Linear acceleration/deceleration (Pr. 29 = 0, initial value)
For the inverter operation, the output frequency is made to change linearly (linear acceleration/
deceleration) to prevent the motor and inverter from excessive stress to reach the set frequency
during acceleration, deceleration, etc. when frequency changes. Linear acceleration/deceler-
ation has a uniform frequency/time slope (refer to Fig. 6-30).
