6.6.1 General MD bits (general bits)
Bit 6 Bit 6=1 An extended tool parameter basic display with 12 parameters (P0 ...P11) is
displayed.
MD 13, "Number of parameter values per D no.", is monitored for greater
than, equal to 12 on Power On and Format tool offset memory.
Bit 6=0 The existing tool parameter basic display with 10 parameters (P0 ... P9) is
displayed.
MD 134, "Number of parameter values per D no.", is monitored for greater
than, equal to 10 on Power On and Format tool offset memory.

All bits in NC MD 5011 affect the axes defined as transverse axes in NC MD 572*, bit 1. All
bits in NC MD 5011 must be set to zero if no transverse axes were defined (i.e. if bit 1 in NC
MD 572* is 0).
Active: At once
Bit 7 All axis-specific @ of axes defined as a transverse axis must be entered as
diameter and are written as diameter (CL 800).
Bit 6 Machine-related actual value and workpiece-related actual value are displayed
in diameter (also see NC SD 5001, bit 0). The actual values in the axis-
specific Service displays are still shown as radii.
Bit 5 Diameter programming in G91.
Bit 4 Diameter programming in G90. The TO wear for tool types 1 to 9 is entered
and displayed in diameter.
Bit 3 The tool length for tool types 1 to 9 is entered and displayed in diameter.
Bit 2 Pulse weighting is diametral for INC handwheel and DRF handwheel. The DRF
offset is displayed in diameter.
Bit 1 Settable ZO and programmable ZO are entered, programmed and displayed in
diameter.
External ZO, PRESET offset, distance to go and REPOS are displayed in
diameter.
Bit 0 Tool wear for tool type 1-9 in diameter
Note:
This machine data applies to transverse axes only.
