1 Alarms
1.5.1 Alarm description
2075* GI configuration not allowed
Scan
When programming DEFINE CONFIGURATION with G function (from NCK).
S
Effect
Command is not executed
S
Interlocking of NC START
S
NC STOP
S
Channel stopped: JOG mode still possible
Explanation
Possible causes:
S
Do leading and following axes have a position measuring system (encoders)?
S
Is the following axis linked to itself as a leading axis?
S
Can the axis be a following axis (MD 1844*)?
S
Link structure switchover not permissible (MD 1844*)
S
Link type for the LA/LS not allowed (MD 1456*/496*)?
S
The following axes must always be real available axes, i.e. a measuring circuit (POS encoder) must be defi-
ned. A measuring circuit must be defined for leading axes/spindles with link structure K2 (actual position link).
S
Leading axes/spindles and following axis are not in the same mode group.
S
Not exactly one leading spindle defined for following spindle.
S
One of the axes in the GI grouping is a fictitious transformation axis.
S
No synchronous positions have been defined for on-the-fly synchronization.
Remedy
Check configuration
Note
Applies as from SW 3
2076* Following spindle not defined
Scan
When programming a spindle as a following spindle which has not been defined as such (from NCK).
S
Effect
G command is not executed
S
Interlocking of NC START
S
NC STOP
S
Channel stopped: JOG mode still possible
Explanation
A GI grouping with the stated axis as a following spindle does not exist.
Remedy
Correct input.
Note
Applies as from SW 3
2077* Spindle not in spindle mode
Scan
The programmed following spindle has a C axis which has been selected for C axis mode.
S
Effect
Command is not executed
S
Interlocking of NC START
S
NC STOP
S
Channel stopped: JOG mode still possible
Explanation
When programming a following spindle which is assigned to a C axis, this C axis must be in spindle mode.
This is not necessary with G401, but a GI grouping must not be defined for the C axis at the same time.
Remedy
Correct mode/input.
2078* Leading spindle not defined
Scan
When programming a spindle as a leading spindle or an axis as a leading axis which have not been defined as
such (from NCK).
S
Effect
G command is not executed
S
Interlocking of NC START
S
NC STOP
S
Stop channel: JOG mode is still possible
Explanation
A GI grouping with the stated axis as a leading axis does not exist
Remedy
Correct input.
Note
Applies as from SW 3
