Shortest Acceleration/Deceleration (Automatic Acceleration/Deceleration); (Pr. 61 To Pr. 63, Pr. 292, Pr. 293) - Mitsubishi Electric FR-A700 Instruction Manual

Acceleration and deceleration
6.11.4

Shortest acceleration/deceleration (automatic acceleration/deceleration)

(Pr. 61 to Pr. 63, Pr. 292, Pr. 293)

The inverter operates in the same conditions as when appropriate values are set in each para-
meter even if acceleration/deceleration time and V/f pattern are not set. This function is useful
when you just want to operate, etc. without fine parameter setting.
