Setting Procedure Of Vector Control (Torque Control) - Mitsubishi Electric FR-A720-00030-NA Instruction Manual

4.5.3

Setting procedure of vector control (torque control)

Perform secure wiring. (Refer to page 37.)
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 192).
· Select online auto tuning. (Pr. 95) (refer to page
· Manual input torque control gain adjustment (refer to page 129)
CAUTION
 The carrier frequencies are selectable from among 2k, 6k, 10k, 14kHz for vector control.
(2k and 6kHz for the FR-A720-02880 (FR-A740-01440) or higher)
Mount the FR-A7AP/FR-A7AL (option).
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 39.)
(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 124.)
Set the speed limit. (Pr. 807)
(Refer to page 126.)
