CAUTION
When selecting this function, re-set the maximum frequency according to the machine.
Intelligent mode selection (Pr. 60)
Pr. 60 "intelligent mode selection"
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.

1, 2
Shortest
acceleration/
deceleration mode
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).
"1": Stall prevention operation level 150%
"2": Stall prevention operation level 180%
Pr. 7, Pr. 8

Optimum
acceleration/
deceleration mode
(Note 2, 4)
Optimum operation can be carried out by fully utilizing the inverter
capabilities in the continuous rating range.
Self-learning automatically sets the corresponding parameters so that the
average current during acceleration/deceleration is equal to the rated current.
Appropriate for applications where the load will not vary by a large ammount.
Pr. 0, Pr. 7, Pr. 8
4
Energy-saving
mode (Note 3, 5)
Tunes the inverter output voltage online to minimize the inverter
output voltage during constant-speed operation.
Appropriate for energy-saving applications such as fan and pump.

Elevator mode
(Note 3)
Automatically controls the inverter output voltage to deliver the
maximum torque in both the driving and regenerative modes. Appropriate
for a counterbalanced elevator.
