6 - 110
Perform secure wiring.
(Refer to section 3.2.)
Set the motor. (Pr. 71) (Refer to section 6.12.2.)
Set the motor capacity and the number of motor poles.
(Pr. 80, Pr. 81) (Refer to section 6.2.2.)
Select a control method. (Refer to section 6.2.2.)
Set the torque command. (Pr. 804)
(Refer to section 6.4.4.)
Set the speed limit. (Pr. 807)
(Refer to section 6.4.5.)
Perform offline auto tuning. (Pr. 96)
(Refer to section 6.12.3.)
Test run
Parameter that must be Set
Torque command
Speed limit
Gain adjustment for torque control
Set "3" (standard motor) or "13" (constant torque motor) in Pr. 71
"Applied motor".
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 "11" (torque control) or "12" (speed-torque switchover) in
Pr. 800 and make torque control valid.
