Configuring an additional positioning axis

Note
The optional function of additional positioning axis/auxiliary spindle is available on PPU16x.3 only.
Auxiliary movements are performed with positioning axes. These axes are not interpolation axes and scarcely affect the
performance of the control. Typical applications for positioning axes are, for example, the tool or workpiece change.
In addition to the NC axes, you can configure up to three (for the turning variant) or two (for the milling variant) positioning
axes.
Prerequisites
● The Drive Bus address (p0918) of the corresponding drive is properly set. For more information, see Section
"Configuring Drive Bus addresses (Page 118)".
● At least one additional positioning axis is activated. For more information, see Section "Activating the optional functions
(Page 126)".

Default the machine data 30110[0] and 30220[0] for MSP2 with this softkey.
Use this softkey or the cursor keys to search for the following machine data and assign the
desired values:
If you use an external spindle encoder for the additional spindle:
•
– 30200[0] = 1
– 30210[0] = 0
– 30230[0] = 4
– 30240[0] = 2
– 31020[0] = resolution of the external spindle encoder
– 31040[0] = 1
– 36300[0] ≤ 2000000 (2 MHz which is the max. frequency of interface X60)
If no external spindle encoder is used for the additional spindle:
•
– 30200[0] = 0
Use this softkey or the cursor keys to search for the following machine data and assign the
desired values:
30100[0] = 0
•
30120[0] = 4
•
30130[0] = 1
•
30134[0]
•
– = 0: bipolar output (± 10 V)
– = 1: unipolar spindle with separate enable and direction signals
– = 2: unipolar spindle with direction-dependent enable
32250[0] = 100
•
32260 = the rated motor speed
•
35000 = 2
•
Press this softkey to activate the value changes. Note that the control system restarts to ac-
cept the new values and the additional spindle can be used in the system.
