Machine data
3.4 Axis-specific machine data
31030 LEADSCREW_PITCH
mm Pitch of leadscrew
-
- -
Description:
The ball screw lead must be entered in the MD (see data sheet: mm/rev or inch/rev).
Special meaning for hydraulic linear drives:
If a hydraulic linear drive (HLA) is configured as rotary axis, it must be specified
in this MD, which drive feedrate in mm corresponds to a programmed revolution (360
degrees).
31040 ENC_IS_DIRECT
- Direct measuring system (no compilation to load position)
-
- 1
Description:
MD = 1:
Encoder for actual position value sensing is attached directly to the machine (without
an intermediate gear unit).
MD = 0:
Encoder for actual position value sensing is attached to the motor (MD31060
$MA_DRIVE_AX_RATIO_NUMERA and MD31050 $MA_DRIVE_AX_RATIO_DENOM are included in the
encoder valuation).
The index[n] of the machine data has the following coding:
[encoder no.]: 0 or 1
Special cases:
An incorrect entry may result in an incorrect encoder resolution, as, for example, the
gear ratios would be calculated incorrectly.
31050 DRIVE_AX_RATIO_DENOM
- Denominator load gearbox
-
- 6
Description:
The load gearbox denominator is entered in this MD.
The index [n] of the machine data has the following coding:
[control parameter set no.]: 0-5
31060 DRIVE_AX_RATIO_NUMERA
- Numerator load gearbox
-
- 6
Description:
The load gearbox numerator is entered in this MD.
The index [n] of the machine data has the following coding:
[control parameter set no.]: 0-5
31070 DRIVE_ENC_RATIO_DENOM
- Denominator measuring gearbox
-
- 1
Description:
The measuring gearbox denominator is entered in this MD.
The index [n] of the machine data has the following coding:
