Torque control by real sensorless vector
control, vector control
4.5.3

Setting procedure of vector control (torque control)

Perform secure wiring. (Refer to page 38.)
Set the motor and encoder. (Pr. 71, Pr. 359, Pr. 369)
Set the motor capacity and the number of motor poles. (Pr. 80, Pr. 81)
Select a control method. (Refer to page 91.)
As required
· Perform offline auto tuning. (Pr. 96) (refer to page 182).
· Select online auto tuning. (Pr. 95) (refer to page
· Manual input torque control gain adjustment (refer to page 126)
CAUTION
⋅ The carrier frequencies are selectable from among 2k, 6k, 10k, 14kHz for vector control.
(2k and 6kHz for the 75K or more)
120
Mount the FR-A7AP.
Set Pr. 71 Applied motor, Pr. 359 Encoder rotation direction and Pr. 369
Number of encoder pulses according to the motor and encoder used.
(Refer to page 40.)
(Refer to page 91.)
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 either "1" (torque control), "2" (speed-torque switchover) or "5"
(position-torque switchover) in Pr. 800 and make torque control valid.
Set the torque command. (Pr. 804)
(Refer to page 121.)
Set the speed limit. (Pr. 807)
(Refer to page 123.)
