HEIDENHAIN MANUALPLUS 620 - 6.17.2 Position monitoring

948 HEIDENHAIN Technical Manual MANUALplus 620
6.17.2 Position monitoring
The parameter object
 CfgControllerAuxil is not required for:
• Virtual axes (MP_axisMode = Virtual)
• Axes that are only for display (MP_axisMode = Display)
 CfgReferencing is not required for:
• Virtual axes (MP_axisMode = Virtual)
The axis positions are monitored by the MANUALplus 620 as long as the
control loop is closed.
The input values for position monitoring depend on the maximum possible
following error (servo lag). Therefore the input ranges for operation with
following error and velocity feedforward are separate.
For both modes of operation there are two range limits for position monitoring.
If the first limit (MP_servoLagMin1, MP_servoLagMax1) is exceeded, the
warning Excessive servo lag in [axis] appears. The machine stops.
This message can be cleared. An actual-to-nominal value transfer is then
executed for the respective axes.
If the second limit (MP_servoLagMin2, MP_servoLagMax2) is exceeded,
the emergency-stop error message "Excessive servo lag in [axis]" appears.
