Feeds (V1)
2-28 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
The following permanent assignment applies to binary coding:
Code Override factor
00000000 0,00 ≙ 0%
00000001 0,01 ≙ 1%
00000010 0,02 ≙ 2%
00000011 0,03 ≙ 3%
00000100 0,04 ≙ 4%

11001000 2,00 ≙ 200%
With Gray coding, the override factors corresponding to the switch setting are entered in
machine data:
MD12010 OVR_ FACTOR_AX_ SPEED [n] (analysis of axis feedrate override switch).
Activation of axis-specific feedrate override
If G33, G34, G35 active: Not effective
If G63 active: Not effective
(the override is set to a fixed value of 100% in the
NC)
If G331, G332 active: Not effective
(the override is set to a fixed value of 100% in the
NC)
Spindle override" DB31, ...DBB0"
One enable signal and one byte is provided on the PLC interface for the override factor for
each of the spindles.
IS "Spindle override" (DB31, ... DBB19)
IS "Override active" (DB31, ... DBX1.7)
The interface for the spindle override can be provided by the PLC in binary-coded or Gray-
coded format.
Machine data:
MD12060 OVR_SPIND_IS_GRAY_CODE (spindle override switch is Gray-coded)
is used to define whether binary or Gray coding is active.
