The MD is bit-coded; the following bits are assigned:
Bit 0 = 0:
"Axis control" is not permissible.
Bit 0 = 1:
"Axis control" is permissible (the axis moves in the speed mode, if the NC/PLC
interface signal DB380x DBX5000.1 (Axis control) is set).
Bit 1:
Reserved for "Axis control".
Bit 2 = 0:
Axis-specific diameter programming not permitted.
Bit 2 = 1:
Axis-specific diameter programming permitted.
Bit 3:
Reserved for "Axis control".
Bit 4 = 0:
For control purposes, the axis can be used by NC and PLC.
Bit 4 = 1:
The axis is exclusively controlled by the PLC.
Bit 5 = 0:
The axis can be used by the NC and PLC.
Bit 5 = 1:
The axis is a permanently assigned PLC axis. However, the axis can be jogged and
referenced.
Axis exchange between channels is not possible. The axis cannot be assigned to the NC
program.
Bit 6 = 0:
The channel-specific interface signal DB3200 DBX6.0 (feedrate disable) has an effect
on the axis, even though it is a PLC-controlled axis.
Bit 6 = 1:
The channel-specific interface signal DB3200 DBX6.0
on the axis, if it is a PLC-controlled axis.
Bit 7 = 0:
The channel-specific interface signal DB3300 DBX4.3 (all axes stationary) is set
dependent on the axis, even though it is PLC-controlled.
Bit 7 = 1:
The channel-specific interface signal DB3300 DBX4.3 (all axes stationary) is set
independent of the axis, if this axis is PLC-controlled..
Bit 8 = 0:
spindle for thread cutting/tapping)
Bit 8 = 1:
The axis is a positioning axis / auxiliary spindle
Bit 9 = 0:
The PRESETON is enabled. PRESETONS is inhibited.
Bit 9 = 1:
The PRESETON is inhibited. PRESETONS is enabled.
