Torque Limit - Parker AC30E Produkthandbuch

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 Lim 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 Lim 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
Lim and Actual Neg Torque Lim diagnostic. These values determine the absolute motor torque limits.
Parameter Name No.
Positive Torque Lim 0415
This parameter sets the maximum allowed level of positive motor torque.
Negative Torque Lim 0416
This parameter sets the maximum allowed level of negative motor torque
Main Torque Lim 0417
This parameter sets the symmetric limit on the maximum allowed motor torque.
Fast Stop Torque Lim 0418
This parameter sets the torque limit used during a Quickstop.
Symmetric Torque Lim 0419
When TRUE, the Negative Torque Lim is forced to reflect the Positive Torque Lim parameter.
