Parameter Acceleration and deceleration
FR-E700 SC EC/ENE 6 - 77
6.7.3 Acceleration and deceleration pattern (Pr. 29)
You can set the acceleration/deceleration pattern suitable for application.
The above parameters can be set when Pr. 160 "User group read selection" = 0.
Linear acceleration/deceleration (Pr. 29 = "0", initial value)
For the inverter operation, the output frequency is made to change linearly (linear acceleration/de-
celeration) to prevent the motor and inverter from excessive stress to reach the set frequency during
acceleration, deceleration, etc. when frequency changes. Linear acceleration/deceleration has a uni-
form frequency/time slope (refer to 6-33).
