SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
The control has been commissioned with default values. Axis A1 is declared as
a linear axis.
S
MD30300: IS_ROT_AX[A1] = 0 (no rotary axis)
S
MD32000: MAX_AX_VELO [A1] = 1000 [mm/min] (max. axis velocity).
Axis A1 is now declared as a rotary axis containing the following machine data:
S
MD30300: IS_ROT_AX[A1] = 1 (rotary axis)
S
MD32000: MAX_AX_VELO [A1] = 1000 [mm/min] (max. axis velocity).
With the next NCK reset, the control system recognizes that axis A1 is defined
as a rotary axis and rescales MD32000: MAX_AX_VELO to [rev./min] with refer-
ence to a rotary axis.
S
MD30300: IS_ROT_AX[A1] = 1 (rotary axis)
S
MD32000: MAX_AX_VELO [A1]= 2.778 [rev./min].
Note
If a scaling machine data item is altered, then the control outputs alarm "4070
Scaling data changed".
The following procedure is recommended when modifying scaling machine data
manually:
1. Set all scaling machine data
2. Carry out NCK reset
3. Set all dependent machine data after the NCK has powered up.
The default machine data can be loaded in different ways.
With SINUMERIK 840Di sl standard user interface 840Di start–up:

Button: "NCK RESET"
Notice
With deleting the NCK data, all user data are lost.
To avoid data loss, a series startup file should be created before the NCK data
are deleted. How to create a series startup file is described in Section 15.2,
Page 15-460.
