1236* GI configuration not allowed
Scan
When programming DEFINE CONFIGURATION via G function. (From NCK)
Effect
Command is not executed. Interlocking of NC START; NC STOP, 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
1240* Following axis not defined
Scan
When programming an axis as a following axis which is not defined as such (from NCK).
Effect
G command is not executed. Interlocking of NC START; NC STOP, channel is stopped: JOG mode still possible.
Explanation
A GI grouping with the stated axis defined as a following axis does not exist.
Remedy
Correct input.
Note
Applies as from SW 3
1244* Axis not in C axis mode
Scan
The following axis is a C axis, is however not in axis mode.
Effect
G command is not executed
Interlocking of NC START; NC STOP, channel is stopped; JOG mode still possible.
Explanation
For all GI commands except G401, C axis mode must also be set for the C axis which is to be programmed as a
following axis. When G401 is programmed, a GI grouping must not also be defined for the assigned spindle.
Remedy
Correct input.
Note
Applies as from SW 3
1248* Leading axis not defined
Scan
When programming an axis as a following axis or a spindle as a leading spindle which are not defined as such.
(from NCK)
Effect
Command is not executed.
Interlocking of NC START; NC STOP, channel stopped: JOG mode still possible.
Explanation
A GI grouping with the stated axis defined as a leading axis does not exist.
Remedy
Correct input.
Note
Applies as from SW 3
1252* Overwriting of GI position not allowed
Scan
When programming a position with GI command.
Effect
GI command is not executed.
Interlocking of NC START; NC STOP, channel stopped: JOG mode still possible.
Explanation
The GI positions cannot be overwritten (enable with MD 1844*, bit 3)
Remedy
Correct input
Note
Applies as from SW 3
