Machine data
2.4 Axis-specific machine data
Description: The mounted position measuring systems can be classified for referencing as
follows with MD34200 $MA_ENC_REFP_MODE:
• MD34200 $MA_ENC_REFP_MODE = 0
If an absolute encoder is available: MD34100 $MA_REFP_SET_POS is taken over
Other encoders: Reference point approach not possible (SW2.2 and higher)
• MD34200 $MA_ENC_REFP_MODE = 1
Referencing of incremental, rotary or linear measuring systems:
Zero pulse on the encoder track
Referencing of absolute, rotary measuring systems:
Replacement zero pulse based on the absolute information
• MD34200 $MA_ENC_REFP_MODE = 3
Referencing on linear measuring systems with distance-coded reference marks:
Linear measuring system with distance-coded reference marks (as specified by
Heidenhain)
• MD34200 $MA_ENC_REFP_MODE = 4 :
Reserved (BERO with 2-edge evaluation)
• MD34200 $MA_ENC_REFP_MODE = 8:
Referencing for linear measuring systems with distance-coded reference marks:
Linear measuring system with distance-coded reference marks over 4 zero marks
(increased safety).
Description: • Absolute encoder:
This machine data contains the absolute encoder status
0: Encoder is not calibrated
1: Encoder calibration enabled (but not yet calibrated)
2: Encoder is calibrated
Default setting for recommissioning: Encoder is not calibrated.
3: No significance, has the same effect as "0"
• Incremental encoder:
This machine data contains the "Referenced status", which can be saved beyond
Power On:
0: Default setting: No automatic referencing
1: Automatic referencing enabled, but encoder not yet referenced
2: Encoder is referenced and at exact stop, automatic referencing becomes
active at the next encoder activation
3: The last axis position buffered before switch off is restored, no auto-
matic referencing
Default setting for recommissioning: No automatic referencing
