AxisCountGet()

int32_t AxisCountGet

(

)

Description:

AxisCountGet returns the number of axes processing on the controller.

Returns

(int32_t) The axis count.

Part of the MotionController-Information 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

Note

The standard default is now zero.
