*2 For offline auto tuning, refer to
3.
Set the motor overheat protection. (Pr.9) (Refer to
Set the rated motor current (A) in Pr.9 Electronic thermal O/L relay.
4.
Setting the motor capacity and the number of motor poles. (Pr.80, Pr.81) (Refer to
Set the motor capacity (kW) in Pr.80 Motor capacity, and set the number of motor poles in Pr.81 Number of motor
poles. (V/F control is performed when the setting is "9999" (initial value).)
5.
Set the rated motor voltage and frequency. (Pr.83, Pr.84) (Refer to
Set the rated motor voltage (V) in Pr.83 Rated motor voltage, and set the rated motor frequency (Hz) in Pr.84
Rated motor frequency.
6.
Set the operation command. (Refer to
Select the start command and speed command.
7.
Test run
As required
• Perform offline auto tuning. (Pr.96) (Refer to
• Select the online auto tuning. (Pr.95) (Refer to
NOTE
• Under this control, rotations are more likely to be uneven than under V/F control. (This control method is not suitable for
grinder, wrapping machine, etc., which require even rotation at a low speed.)
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
