The inverter automatically sets appropriate parameters for operation.

z

 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.

 If the intelligent operation mode has been selected, entry of the jog signal or RT (second function

selection) signal during an inverter stop starts ordinary operation, with priority given to jog operation or
second function selection. After a start in the intelligent operation mode, neither the JOG signal nor the RT
signal is accepted.

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).

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 amount.

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.
