NOTES Uneven rotation slightly increases as compared to the V/F control. It is not suitable for
machines such as grinding machine and wrapping machine which requires less uneven
rotation at low speed.
When a surge voltage suppression filter (FFR-DT or FFR-SI) is connected between the
inverter and motor, output torque may decrease.
Perform secure wiring.
(Refer to section 3.2.)
Set the motor. (Pr. 71) (Refer to page 5-12.)
For other settings of Pr. 71, refer to section 6.7.2.
Refer to section 5.1.8 for offline auto tuning.

Set the motor capacity (Pr. 80) (refer to page 5-12).
Set the operation command (refer to section 5.2).
Test run
Set motor capacity (kW) in Pr. 80 "Motor capacity".
(V/f control is performed when the setting is "9999" (initial value).
Select the start command and speed command.
1) Start command
– Operation panel: Setting by pressing the RUN key
– External command: Setting by forward rotation or reverse
rotation command (terminal STF or STR)
2) Speed command
– Operation panel: Setting by pressing the digital dial
– External analog command (terminal 2 or 4):
Give a speed command using the analog signal input to
terminal 2 (or terminal 4).
– Multi-speed command:
The external signals (RH, RM, RL) may also be used to give
speed command.
Perform offline auto tuning (Pr. 96, refer to section 5.1.8).
Set motor excitation current (Pr. 82, refer to section 6.7.3).
Set slip compensation (Pr. 245, Pr. 246, Pr. 247, refer to section 6.2.3).
