Refer to page 113 for offline auto tuning.
Set the motor capacity and the number of motor poles.
(Pr. 80, Pr. 81) (Refer to page 76)
Select the control method.(Pr. 800) (Refer to page 76)
Set the operation command. (Refer to page 183)
As required
Perform offline auto tuning. (Pr. 96) (Refer to page 113)
Set slip compensation. (Pr. 245, Pr. 246, Pr. 247) (Refer to page 84)
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.)
Parameters referred to

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).
Set "30" in Pr. 800 to make general-purpose magnetic flux vector control valid.
Select the start command and speed command.
(1)Start command
1)Operation panel: Setting by pressing
2)External command: Setting by forward rotation or reverse rotation
command (terminal STF or STR)
(2)Speed command
1)Operation panel: Setting by pressing
2)External analog command (terminal 2 or 4):
Give a speed command using the analog signal input to terminal 2 (or
terminal 4).
3)Multi-speed command:
The external signals (RH, RM, RL) may also be used to give speed
command.
