HEIDENHAIN MANUALPLUS 620 - 6.4.7 Encoder monitoring

January 2012 6.4 Encoders 665
6.4.7 Encoder monitoring
HEIDENHAIN contouring controls monitor the signal transmission from the
encoders.
The parameter object CfgEncoderMonitor is not required for:
 Virtual axes (MP_axisMode = Virtual)
Position encoder Activate the following monitoring functions for the position encoders:
 MP_checkAbsolutPos:
Monitor the absolute position of position encoders with distance-coded
reference marks
 MP_checkSignalLevel:
Monitor the encoder signal level of the position measuring systems
 MP_checkFrequency:
Monitor the edge separation of the position measuring systems
 MP_checkRefDistance:
Monitor the reference mark of the spindle encoder (distance between zero
crossovers of the spindle)

Note
The edge separation is monitored by the CC controller unit. Therefore, the
MP_checkFrequency parameter is currently not available on the TNC 320
and the MANUALplus 620 with analog command interface to the drive
motors.
