The RMP Motion Controller APIs

◆ SoftwareNegLimitTriggerValueGet()

double SoftwareNegLimitTriggerValueGet ( )
Description:
SoftwareNegLimitTriggerValueGet returns the Software Negative Position limit value.
Returns
(double) The limit position, in User Units.
Remarks
This function is also available in RapidSequencer.

Part of the Limits and Action Configuration method group.

Sample Code:
Axis: Configuration
controller.AxisCountSet(controller.AxisCountGet() + 1); // Configure one additional axis to be used for the phantom axis
int axisNumber = controller.AxisCountGet() - 1; // Set the axis number to the last axis on the network (subtract one because the axes are zero indexed)
axis = controller.AxisGet(axisNumber); // Initialize Axis class
HelperFunctions.CheckErrors(axis); // [Helper Function] Check that the axis has been initialized correctly
// These limits are not meaningful for a Phantom Axis (e.g., a phantom axis has no actual position so a position error trigger is not necessary)
// Therefore, you must set all of their actions to "NONE".
axis.ErrorLimitActionSet(RSIAction.RSIActionNONE); // Set Error Limit Action.
axis.HardwareNegLimitActionSet(RSIAction.RSIActionNONE); // Set Hardware Negative Limit Action.
axis.HardwarePosLimitActionSet(RSIAction.RSIActionNONE); // Set Hardware Positive Limit Action.
axis.HomeActionSet(RSIAction.RSIActionNONE); // Set Home Action.
axis.SoftwareNegLimitActionSet(RSIAction.RSIActionNONE); // Set Software Negative Limit Action.
axis.SoftwarePosLimitActionSet(RSIAction.RSIActionNONE); // Set Software Positive Limit Action.
const double positionToleranceMax = Double.MaxValue / 10.0; // Reduce from max slightly, so XML to string serialization and deserialization works without throwing System.OverflowException
axis.PositionToleranceCoarseSet(positionToleranceMax); // Set Settling Coarse Position Tolerance to max value
axis.PositionToleranceFineSet(positionToleranceMax); // Set Settling Fine Position Tolerance to max value (so Phantom axis will get immediate MotionDone when target is reached)
axis.MotorTypeSet(RSIMotorType.RSIMotorTypePHANTOM); // Set the MotorType to phantom
RapidSetup:
Go to axis screen->Limits & Actions. In the image below, SoftwareNegLimitTriggerValueGet returns the value in the Trigger value box shown in the Negative (-) Software box. It currently triggers at -1125899890065410.
