AX- Ser i es Mo t i o n Co n t r o l l er I n s t r u c t i o n s Ma n u a l
After the maximum torque is set, the torque of the motor will be limited to the Setting Value to protect the motor from
damage caused by the excessive torque when large resistance is encountered.
DMC_SetTorqueLimit can be used to set the maximum torque of an axis with the unit: Nm.
DMC_SetTorqueLimit can be used only in CSP or CSV mode
Troubleshooting
When an error occurs during the execution of the instruction or the axis enters "Errorstop" state, bError changes to
True and the axis stops running. To confirm current error state, see the error code in ErrorID.
Programming Example
The example illustrates how to use DMC_SetTorqueLimit.
Timing Diagram
1.
Set the maximum rated torque of the axis to 0.1Nm before the operation. Then the operation is performed at a
constant velocity.
2.
Use the external force to make the axis stop (Step 1) during operation. It can be found that the actual torque
of the axis reaches 0.1Nm. Then remove the external force.
3.
Set the maximum rated torque to 0.2 Nm and use the external force to make the axis stop (Step2). It is found
that the actual torque of the axis reaches 0.2 Nm at the moment. Finally, the Following Error is generated and
Servo ON is disabled.
