Parker AC30 series - Torque Limit

D-116 Parameter Reference
AC30V series Variable Speed Drive
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.
PNO Parameter Descriptions
0415 Positive Torque Lim
This parameter sets the maximum allowed level of positive motor torque.
0416 Negative Torque Lim
This parameter sets the maximum allowed level of negative motor torque
0417 Main Torque Lim
This parameter sets the symmetric limit on the maximum allowed motor torque.
0418 Fast Stop Torque Lim
This parameter sets the torque limit used during a Quickstop.
0419 Symmetric Torque Lim
When TRUE, the
Negative Torque Lim
is forced to reflect the
Positive Torque Lim
parameter.
0420 Actual Pos Torque Lim
This diagnostic indicates the final actual positive torque limit including any current limit or inverse time current limit action.
0421 Actual Neg Torque Lim
This diagnostic indicates the final actual negative torque limit including any current limit or inverse time current limit action.
