5.4.3 Setting procedure for Vector control (torque
control)
Vector Vector Vector
Operating procedure
1.
Perform secure wiring. (Refer to
Install a Vector control compatible option.
2.
Set the option to be used (Pr.862).
Set Pr.862 Encoder option selection according to the option to be used. (Refer to
3.
Set the motor and the encoder (Pr.71, Pr.359 (Pr.852), and Pr.369 (Pr.851)). (Refer to
4.
Set the overheat protection of the motor (Pr.9). (Refer to
When using the SF-V5RU or a motor equipped with a thermal sensor, set Pr.9 = 0 A.
5.
Set the motor capacity and the number of motor poles (Pr.80 and Pr.81). (Refer to
V/F control is performed when the setting is "9999" (initial value).
6.
Set the rated motor voltage and frequency (Pr.83 and Pr.84). (Refer to
7.
Select the control method (Pr.800). (Refer to
Select Pr.800 Control method selection = "1" (torque control), "2" (speed/torque switchover), or "5" (position/
torque switchover) to enable torque control.
8.
Set the torque command (Pr.804). (Refer to
9.
Set the speed limit (Pr.807). (Refer to
10.
Set the acceleration time to "0" (Pr.7). (Refer to
11.
Perform the test operation.
As required
• Perform offline auto tuning (Pr.96). (Refer to
• Select the online auto tuning (Pr.95). (Refer to
• Adjust the torque control gain manually. (Refer to
NOTE
• The carrier frequency is limited during Vector control. (Refer to
• Torque control is not available under the Vector control with PM motors.
• To give the constant torque command in the constant output range, set "1 or 11" in Pr.803 Constant output range torque
characteristic selection. (Refer to
• For the settings for the SF-V5RU, refer to
