Acceleration And Deceleration Pattern (Pr. 29, Pr. 140 To Pr. 143, Pr. 380 To Pr. 383, Pr. 516 To Pr. 519) - Mitsubishi Electric FR-A700 Instruction Manual

Parameter
6.11.3 Acceleration and deceleration pattern (Pr. 29, Pr. 140 to Pr. 143, Pr. 380 to
Pr. 383, Pr. 516 to Pr. 519)
You can set the acceleration/deceleration pattern suitable for application.
You can also set the backlash measures that stop acceleration/deceleration once at the
parameter-set frequency and time during acceleration/deceleration.
