Set the motor capacity and the number of motor poles.
(Pr. 80, Pr. 81) (Refer to page 95)
Set motor capacity (kW) in Pr. 80 Motor capacity and
the number of motor poles (number of poles) in Pr. 81 Number of motor poles.
(V/F control is performed when the setting is "9999" (initial value).
Select the control method. (Pr. 800) (Refer to page 95)
Set "20" (initial value) in Pr. 800 to make Advanced magnetic flux vector control
valid.
Set the operation command. (Refer to page 50)
Select the start command and speed command.
(1)Start command
1)Operation panel: Setting by pressing on the operation panel
2)FL remote communication command: Setting by forward rotation or
reverse rotation command (STF or STR signal)
(2)Speed command
1)Frequency command sent through FL remote communication
2)Operation panel: Setting by turning on the operation panel
3)Multi-speed command:
RH, RM, and RL signals of FL remote communication may also be used to
give a speed command.
Test run
As required
Perform offline auto tuning. (Pr. 96) (Refer to page 127)
NOTE
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 (FR-ASF-H/FR-BMF-H) is connected between the inverter and motor, output
torque may decrease.)
