6.1.5 Reading Axis Information
Module 9038 Reading general axis information
With Module 9038 you can interrogate the general status information of the
axes. You can ask for the status of a specific axis or of all axes at once. Bits 0
to 8 represent the axes 1 to 9 and bit 15 represents the spindle. 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: 0 to 8 represent axes 1 to 9,
15 represents the spindle
Bit-coded output for all axes: –1

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 servo-controlled axis (spindle), only display or not active
1: Servo-controlled axis (spindle)
3 Maximum temperature of the motor [°C]
4 0: No 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)
