Shortest Acceleration/Deceleration Mode (Pr. 60 To Pr. 63) - Mitsubishi Electric FR-E540 K-EC Series Instruction Manual

When selecting this function, re-set the maximum frequency according to
the machine.

4.2.24 Shortest acceleration/deceleration mode (Pr. 60 to Pr. 63)

Pr. 60 "shortest acceleration/deceleration mode"
Pr. 61 "reference current"
Pr. 62 "reference current for acceleration"
Pr. 63 "reference current for deceleration"
The inverter automatically sets appropriate parameters for operation.
If you do not set the acceleration and deceleration times and V/F pattern, you can
run the inverter as if appropriate values had been set in the corresponding
parameters. This operation mode is useful to start operation immediately without
making fine parameter settings.

Description
Set to accelerate/decelerate the motor in the
shortest time.
The inverter makes acceleration/deceleration in the
shortest time using its full capabilities. During
deceleration, an insufficient brake capability may
cause the regenerative overvoltage alarm (E.OV3).
