Shortest Acceleration/Deceleration And Optimum Acceleration/Deceleration - Mitsubishi Electric FR-A820-00046 Instruction Manual

Parameters
5.8.6

Shortest acceleration/deceleration and optimum acceleration/deceleration

(automatic acceleration/deceleration)
The inverter can be operated with the same conditions as when the appropriate value is set to each
parameter even when acceleration/deceleration time and V/F pattern are not set. This function is use-
ful for operating the inverter without setting detailed parameters.
