∗1 Refer to chapter 4 of the Instruction Manual (applied) for other settings of Pr. 71.
∗2 Refer to page 50 for offline auto tuning.
Set the motor capacity.
(Pr. 80) (Refer to page 48)
Set motor capacity (kW) in Pr. 80 Motor capacity.
(V/F control is performed when the setting is "9999" (initial value).
Set the operation command. (Refer to page 54)
Select the start command and speed command.
(1)Start command
1)Operation panel: Setting by pressing of the operation panel
2)External command: Setting by forward rotation or reverse rotation
command (terminal STF or STR)
(2)Speed command
1)Operation panel: Setting by turning of the operation panel
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.
Test run
As required
Perform offline auto tuning. (Pr. 96) (Refer to page 50)
Set motor excitation current. (Pr. 82) (Refer to page 50)
Set slip compensation. (Pr. 245, Pr. 246, Pr. 247) (Refer to page 90)
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.
