Vector Vector Vector
Test run
Perform secure wiring.
(Refer to page 2-77.)
Set the motor and the encoder.
(Pr. 71, Pr. 359 (Pr.852), Pr. 369 (Pr.851)) (Refer to page 2-84.)
Select the position command source. (Pr. 419)
Select the control method. (Pr. 800) (Refer to page 5-61)
As required
앫
Set the electronic gear. (Refer to page 5-185.)
앫
Set the position adjustment parameters. (Refer to page 5-187.)
앫
Adjust the position control gain. (Refer to page 5-189.)
앫
Set the torque limit. (Refer to page 5-90.)
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 5-61.)
Set Pr. 71 "Applied motor", Pr. 359 (Pr.852)"Encoder
rotation direction", and Pr. 369 (Pr.851)"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 5-138.)
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 a vector control compatible option.
Set the rated motor voltage and frequency.
(Pr. 83, Pr. 84) (Refer to page 2-84)
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 5-176.)
Set the overheat protection of the motor. (Pr. 9)
(Refer to page 5-303.)
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".
Set the option to be used. (Pr. 862)
Set Pr. 862 "Encoder option selection" according to the
option to be used (refer to page 5-69).
