Acceleration And Deceleration Pattern (Pr. 29, Pr. 140 To Pr. 143) - Mitsubishi Electric FR-F740 EC Instruction Manual

Parameter
6.6.3

Acceleration and deceleration pattern (Pr. 29, Pr. 140 to Pr. 143)

You can set the acceleration/deceleration pattern suitable for application.
You can also set the backlash measures that stop acceleration/deceleration once at the pa-
rameter-set frequency and time during acceleration/deceleration.

The above parameters can be set when Pr. 160 = 0.
Linear acceleration/deceleration (Pr. 29 = 0, initial value)
When the frequency is changed for acceleration, deceleration, etc. in inverter operation, the out-
put frequency is changed linearly (linear acceleration/deceleration) to reach the set frequency
without straining the motor and inverter. Linear acceleration/deceleration has a uniform fre-
quency/time slope (refer to Fig. 6-34).
