Machine data
2.4 Axis-specific machine data
Description: • Incremental encoder with zero mark(s):
The position value which is set as the current axis position after detection
of the zero mark and traversal of the distance REFP_MOVE_DIST +
REFP_MOVE_DIST_CORR (relative to zero mark). REFP_SET_POS of the reference
point number, which is set at the instant that the edge of the reference cam
signal rises (NC/PLC interface signal DB380x DBX2.4 - .7 (Reference point
value 1 to 4)), is set as the axis position.
• Distance-coded measuring system:
Target position which is approached when MD34330 $MA_REFP_STOP_AT_ABS_MARKER
is set to 0 (FALSE) and two zero marks have been crossed.
• Absolute encoder:
MD34100 $MA_REFP_SET_POS corresponds to the correct actual value at the cal-
ibration position.
The reaction on the machine depends on the status of MD34210
$MA_ENC_REFP_STATE: When MD34210 $MA_ENC_REFP_STATE = 1, the value of MD34100
$MA_REFP_SET_POS is transferred as the absolute value.
When MD34210 $MA_ENC_REFP_STATE = 2 and MD34330 $MA_REFP_STOP_AT_ABS_MARKER =
0 (FALSE), the axis approaches the target position stored in MD34100
$MA_REFP_SET_POS.
The value of MD34100 $MA_REFP_SET_POS that has been set via NC/PLC interface
signal DB380x DBX2.4 - .7 (Reference point value 1 to 4) is used.
Related to:
NC/PLC interface signal DB380x DBX2.4 - .7 (Reference point value 1 to 4)
Description: An axis can also be referenced in the follow-up mode under JOG+REF mode by
means of an external motion.
