Test run
Perform secure wiring.
(Refer to page 66.)
Set the motor and the encoder.
(Pr.71, Pr.359, Pr.369) (Refer to page 68.)
Select the position command source. (Pr.419)
Select the control method. (Pr.800) (Refer to page 164)
As required
• Set the electronic gear. (Refer to page 247.)
• Set the position adjustment parameters. (Refer to page 249.)
• Adjust the position control gain. (Refer to page 251.)
• Set the torque limit. (Refer to page 185.)
Set Pr.800 = "3" (position control), "4" (speed - position switching) or
"5" (position - torque switching) to enable position control.
Set the motor capacity and the number of motor poles.
(Pr.80, Pr.81) (Refer to page 164.)
Set Pr.71 Applied motor, Pr.359 Encoder rotation direction, and
Pr.369 Number of encoder pulses according to the motor and encoder.
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).)
Set the positioning parameters.
(Pr.465 to Pr.494 and Pr.1222 to Pr.1281)
(Refer to page 232.)
Position command by contact input.
Set Pr.419="0 (initial value)".
Set Pr.419="2" that indicates the position
command by inverter pulse train input.
Install FR-A8AP (option).
Set the rated motor voltage and frequency.
(Pr.83, Pr.84) (Refer to page 68)
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.
Select the command pulse type. (Pr.428)
(Refer to page 244.)
Set the overheat protection of the motor. (Pr.9)
(Refer to page 331.)
Set the rated motor current (A) in Pr.9 Electronic thermal O/L relay.
When using the SF-V5RU or a motor equipped with a thermal sensor,
set Pr.9 = "0A".
