Linear axis
MD30501 $MA_INDEX_AX_NUMERATOR[AX1] = 10
MD30502 $MA_INDEX_AX_DENOMINATOR[AX1] = 1
MD30503 $MA_INDEX_AX_OFFSET[AX1] = -200
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB[AX1] = 3
MD30300 $MA_IS_ROT_AX[AX1] = FALSE
MD36100 $MA_POS_LIMIT_MINUS[AX1] = -200
MD36110 $MA_POS_LIMIT_PLUS[AX1] = 200
With the machine data above, axis 4 is defined as a linear axis and an indexing axis with
equidistant positions every 10 mm starting at -200 mm.
The following indexing positions result:
-200, -190, -180 mm etc.
These indexing positions continue until the software limit switch is reached (in this case
200 mm).
Hirth tooth system
MD30502 $MA_INDEX_AX_DENOMINATOR[AX4] = 360
MD30503 $MA_INDEX_AX_OFFSET[AX4] = 0
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB[AX4] = 3
MD30300 $MA_IS_ROT_AX[AX4] = TRUE
MD30310 $MA_ROT_IS_MODULO[AX5] = TRUE
MD30505 $MA_HIRTH_IS_ACTIVE[AX4] = TRUE
With the machine data above, axis 4 is defined as a modulo rotary axis and an indexing axis
with Hirth tooth system and equidistant positions every 1° starting at 0°.
