6.1.7 Reading axis information
Module 9038 Read general axis information
With Module 9038 you can interrogate the general status information of the
axes. You can interrogate the status of a specific axis or of all axes at once.
Bits 0 to 14 represent axes 1 to 15. Bit 15 represents the spindle (depends on
MP4020 bit 14). If status information is read for only one axis, only bit 0 is
changed. The following table shows the meanings of the return codes:
Call:
Axis-specific: Dependence on MP4020 bit 14
Bit-encoded output for all axes: –1
PS B/W/D/K <Status information>
See table above

PL B/W/D <Information>
Error code:
Status
information
Meaning
0 0: Axis (spindle) not active (MP10 or MP3010 or no encoder)
1: Axis (spindle) active
1 Depending on the current traverse range:
0: NC axis or not active
1: PLC axis
2 0: No closed-loop axis (spindle), only display or not active
1: Closed-loop axis (spindle)
3 Maximum temperature of the motor [°C]
4 0: Not a Hirth axis
1: Hirth axis (MP420)
5 Hirth grid [1/10 µm] (MP430)
6 Modulo value (MP810)
7 0: Linear axis or not active
1: Rotary axis in at least one of the traverse ranges
8 0: Analog axis (spindle) or not active
1: Digital axis (spindle)
9 0: Not a slave axis
1: Slave axis
