Parameters Torque control under Real sensorless vector control and vector control
FR-A800 5 - 137
5.4.3 Setting procedure for vector control (torque control)
Fig. 5-43: Setting procedure for vector control (torque control)
NOTES The carrier frequency is limited during vector control. (Refer to page 5-230.)
Torque control is not available under the vector control with PM motors with a resolver.
Vector Vector Vector
Test run
Perform secure wiring.
(Refer to page 2-77.)
Set motor and encoder.
(Pr. 71, Pr. 359 (Pr. 852), Pr. 369 (Pr. 851))
Set the torque command. (Pr. 804)
(Refer to page 5-138.)
Set the speed limit. (Pr. 807)
(Refer to page 5-142.)
Select the control method. (Pr. 800) (Refer to page 5-61)
As required
앫
Perform offline auto tuning. (Pr. 96) (Refer to page 5-72)
앫
Select online auto tuning. (Pr. 95) (Refer to page 5-482.)
앫
Adjusting the torque control gain manually (Refer to page 5-150)
Select Pr. 800 "Control method selection" = "1 (torque control)", "2
(speed/torque switch)", or "5 (position torque switch)" to enable
torque control.
Set the motor capacity and the number of motor poles. (Pr. 80, Pr. 81)
(Refer to page 5-61.)
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).)
Install a vector control compatible option.
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 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".
Set the overheat protection of the motor. (Pr. 9)
(Refer to page 5-303.)
Set Pr. 71 "Applied motor", Pr. 359 (Pr. 852) "Encoder rotation
direction" or Pr. 369 (Pr. 851) "Number of encoder pulses"
according to the motor and encoder used. (Refer to page 2-84.)
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).
