This machine data displays the quadrant error plane at the instant at which the appropriate axis
executed the last speed zero crossing when quadrant error compensation (QEC) is active. The
display is called by means of softkey Service QEC in the "Circularity test" menu.
Note:
This machine data is effective only if one of the two quadrant error compensation modes is
active.

This machine data displays the error measurement time at the instant at which the appropriate
axis executed the last speed zero crossing. The display is called by means of softkey Service
QEC in the "Circularity test" menu.
Note:
This machine data is effective only if one of the two quadrant error compensation modes is
active.

The "Drive configuration" machine data contains the descriptive information for a drive module
which is actually installed. In the case of a two-axis module, the data contains two sets of
information. Machine data 10000 to 10014 are assigned to physical addresses 1 to 15.
Bits 0 - 7
Drive number:
These bits assign the physical drive address to the logical
drive number (1 - 15) for digital drives.
Bit 8
Active identifier:
0 ˆ
= positive
(no machine data required)
1 ˆ
= active
(used as control axis/machine data
required)
Bits 9 - 11
Module type:
000 ˆ
= Single-axis module (1)
010 ˆ
= Two-axis module (left - 2L)
011 ˆ
= Two-axis module (right - 2R)
Bit 12
Drive type:
0 ˆ
= FDD
1 ˆ
= MSD
