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.

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.
