Torque Limit
Parameters::Motor Control::Torque Limit
This function allows you to set the maximum level of motor rated torque which is allowed before torque limit action occurs.
If the estimated motor torque is greater than the
Actual Pos Torque Limit value, the motor speed is controlled to maintain the torque at this
level. A similar situation occurs if the estimated motor torque is less than the Actual Neg Torque Limit value.
The torque limit function has separate positive and negative torque limits. In addition, a symmetric main torque limit is also provided.
The lowest positive and negative torque limits (including any current limit or inverse time current limit action) is indicated in the
Actual Pos
Torque Limit and Actual Neg Torque Limit diagnostic. These values determine the absolute motor torque limits.
PNO Parameter Descriptions
0415
Positive Torque Limit
This parameter sets the maximum allowed level of positive motor torque.
0416
Negative Torque Limit
This parameter sets the maximum allowed level of negative motor torque
0417
Main Torque Limit
This parameter sets the symmetric limit on the maximum allowed motor torque.
0418
Quickstop Torque Limit
This parameter sets the torque limit used during a Quickstop.
0419
Symmetric Torque Limit
When TRUE, the Negative Torque Limit is forced to reflect the Positive Torque Limit parameter.
0420
Actual Pos Torque Limit
This diagnostic indicates the final actual positive torque limit including any current limit or inverse time current limit action.
0421
Actual Neg Torque Limit
This diagnostic indicates the final actual negative torque limit including any current limit or inverse time current limit action.
