Override active
Edge evaluation: no
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Feed rate override active:
The axisspecific feed rate override between 0 and a maximum of 200% entered in the PLC
interface is used.
The override factor is defined using the machine data:
MD12000 $MN_OVR_AX_IS_GRAY_CODE (axis feed rate override switch gray coded)
and
MD12010 $MN_OVR_FACTOR_AX_SPEED [n] (evaluation of the axis feed rate override switch).
Spindle override active:
The spindle override - input at the PLC interface - of 0 to a maximum of 200% is taken into account.
The override factor is entered using the machine data:
MD12060 $MN_OVR_SPIND_IS_GRAY_CODE (spindle override switch, Gray coded)
and
MD12070 $MN_OVR_FACTOR_SPIND_SPEED [n] (evaluation of the spindle override switch).
Signal state 0 or
edge change
1 → 0
The existing axisspecific feed rate override or spindle override is not active.
If the feed rate override is inactive, "100%" is used as the internal override factor.
Exceptions are the zero setting for a binary interface and the 1st switch setting for a Graycoded
interface. In these cases, the override factors entered at the PLC interface are used.
For a binary interface, the override factor = 0. For a graycoded interface, the value entered in the
machine data for the 1st switch setting is output as the override value.
Application
example(s)
The override value is generally specified using the axisspecific feed rate override switch or the
spindle override switch on the machine control panel.
The "feed rate override active" signal can be used to enable the feed rate override switch from the
PLC user program, e.g. using the key-operated switch when commissioning a new NC program.
Special cases,
errors, ......
The spindle override is always accepted with 100% in the spindle "Oscillation mode".
The spindle override acts on the programmed values before the limits (e.g.
G26
,
LIMS
...) intervene.
The feed rate override is ineffective for:
•
active
G33
•
active
G63
(the override is defined in the NC at 100%)
•
active
G331
,
G332
(the override is defined in the NC at 100%)
The spindle override is inactive for:
•
active
G63
(the override is defined in the NC at 100%)
