1.5.1 Alarm description
1220* GI configuration not allowed
Scan
When programming DEFINE CONFIGURATION with G function. (From NCK)
Effect
Command is not executed. Interlocking of NC START
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
1224* Change of KF not allowed
Scan
When a new link factor is entered via G function (from NCK).
Effect
The command is not executed, the previous link factor is kept.
Interlocking of NC START
Explanation
The link factor default setting must not be changed (MD 1844*).
Remedy
Change default setting if necessary.
Note
Applies as from SW 3
1228* Link factor KF not allowed
Scan
When entering a new link factor via G function (from NCK).
Effect
Command is not executed, the previous link factor remains. Interlocking of NC START; NC STOP. Channel stop;
JOG mode still possible.
Explanation
The entered link factor does not lie within the range 0.00000001 <= /KF/ <= 10.000000 or denominator J = 0 or the
individual values are so high that internal overflows are the result.
Remedy
Correct or shorten link factor KF
Note
Applies as from SW 3
1232* Change of link factor KF not allowed
Scan
When entering a new link factor via G function (from NCK).
Effect
Command is not executed, the previous link factor remains. Interlocking of NC START; NC STOP. Channel stop;
JOG mode still possible.
Explanation
The link factor default setting must not be changed (MD 1844*).
Remedy
Change default setting if necessary.
Note
