1196* Reconfiguration not allowed
Scan
When RECONFIGURING with G function (G401), i.e. when adding, removing a leading axis or changing the link
structure or on CLEAR configuration (from NCK)
Effect
Interlocking of NC START
Explanation
"Reconfiguration allowed" is not set (MD 1844, bit 1)
Remedy
Correct input, set MD bit
Note
Applies as from SW 3
1200* Division wrong
S
Scan
Cyclic
S
Effect
Interlocking of NC START
S
Machining is interrupted
Explanation
The "Division from PLC" function is not possible because:
S
NC machine data "Number of divisions" has an invalid value
S
NC machine data "Absolute division increment" has an invalid value
S
NC machine data "Division offset" has an invalid value
S
Indexing axis has been defined as a rounding axis, which is impermissible.
S
Remedy
Check and correct the relevant machine data.
1204* Traversing range limits exceeded
S
Scan
Cyclic (only with linear axes)
S
Effect
Interlocking of NC START
S
Machining is interrupted
S
Set value 0 (abrupt, no deceleration ramp)
Explanation
If no software limit switches or working area limitations are active, it is theoretically possible to exceed the
maximum possible traversing range (set by the combination of axis-specific position control resolution and input
resolution). As this would lead to traversing errors, however, the traversing range limit is monitored and, when it is
exceeded, alarm 1204* is set.
Remedy
Traverse back into the permissible range in the opposite direction using INC or JOG mode.
1208* Link factor KF not allowed
Scan
When entering a new link factor via the G function (from NCK).
Effect
Command is not executed, the previous link factor is maintained. Interlocking of NC start.
Explanation
Denominator J=0 is programmed, link factor incorrectly programmed, following axis not programmed.
Remedy
Correct link factor
Note
Applies as from SW 3
1212* Overwriting of pos. not allowed
Scan
When programming a position with GI command.
Effect
G command is not executed: interlocking of NC START
Explanation
GI positions must not be overwritten (enabled with MD 1844 *, bit 3)
Remedy
Correct input
Note
Applies as from SW 3
1216* Reconfiguration/deletion not allowed
Scan
When RECONFIGURING with G function (G401), i.e. when a leading axis is added or removed or when the link
structure is altered or on DELETE CONFIGURATION (from NCK)
Effect
Interlocking of NC START, NC STOP, i.e. channel is stopped: command is not executed: JOG mode still possible.
Explanation
RECONFIGURATION or DELETE CONFIGURATION is not possible until LINK OFF has been set.
RECONFIGURATION is only possible after DELETE CONFIGURATION. Program a new configuration block
(G401); following axis already exists.
Remedy
First set LINK OFF for the GI grouping in question.
Note
Applies as from SW 3
