d5 parameters set the Torque Control function.
The Torque Control function controls the output torque of the motor. You can use Torque Control for roller drives, winders, unwinders, conveyors and other machines that use tension control and push/pull applications. When there is no more material and the machine suddenly has no load, the drive uses Torque Control and the speed limit function to keep the rotation speed of the motor from increasing.
Set A1-02 [Control Method Selection] to one of these values to use Torque Control:
-
3 [Closed Loop Vector]
-
4 [Advanced Open Loop Vector]
-
6 [PM Advanced Open Loop Vector]
-
7 [PM Closed Loop Vector]
Note:
When you use Torque Control and A1-02 = 4, use a motor designed for winding applications.
Use one of these methods to enable Torque Control:
