1172* Speed limit exceeded Acknowledgement key
Cyclic in servo cycle when LINK ON has been set for the following axis (from servo)
No reaction, machining not interrupted; the speed of the following axis is limited to the programmed maximum
value; the setpoint determined by the compensatory controller is not used in the calculation.
The maximum value set for the following axis/spindle has been exceeded. Synchronism is in danger.
Reduce feedrate or speed of leading axes. Check the speed limit value. Check the link factors.
Applies as from SW 3
1176* Acceleration limit exceeded Acknowledgement key
Cyclic in servo cycle when LINK ON has been set for the following axis and MD bit “Suppression of acceleration
limitation” is not set (from servo).
No reaction. Machining is not interrupted; when interface signal “Acceleration limitation synchronous” is set; travel
is continued at maximum acceleration; any suppressed partial setpoints are traversed afterwards;
If interface signal “Acceleration limit synchronous” has not been set; any suppressed partial setpoints are not tra-
versed. The setpoint determined by the compensatory controller is not used in the calculation.
The maximum value programmed for the following axis has been exceeded. Synchronism is in danger.
Reduce the acceleration of the leading axes. Check the acceleration limit value. Check the link factors. Set MD bit
“Suppress acceleration limitation”.
Applies as from SW 3
1180* Following spindle corrected autom. Reset key
An error has occurred that has cancelled “Mode Group Ready”.
Cyclic in servo cycle when LINK ON is set
Machining is interrupted. Interlocking of NC START: switchover to actual position link.
An error has occurred for an axis/spindle in the mode group which usually causes a switch over to follow-up mode.
As long as the following axis is not affected by the fault, the link is maintained until “Delay controlled follow-up” has
been executed.
Remove error from faulty axis/spindle.
Applies as from SW 3
1192* Centering edge violated Acknowledgement key
Cyclic in IPO cycle when LINK ON and PLC interface signal “Semi-automatic centring is active” are set.
Interlocking of NC START, any movement towards edges already recognized are suppressed.
The alarm is set when the axis tries to traverse across an edge that has already been recognized or if PLC inter-
face signal “Semi-automatic centring on” and “First edge approached” have been set without first traversing the
following axis.
Move following axis away from the edge (in opposite direction to approach direction: if necessary remove interface
signal “x edge approached” traverse at least 1 increment between interface signal “Semi-automatic centring on”
and “First edge approached”.
Applies as from SW 3 up to SW 4.3
1192* No synchronous/switching positions defined Reset key
When synchronizing or switching on in relation to a position from PLC.
Interlocking of NC START, MACHINING STOP
An attempt has been made to synchronize master and slave axes/spindles from PLC, or to switch on with
reference to a position, without there being any valid switching or synchronizing positions. Synchronization or
switching on with reference to a position is therefore not possible.
For example, specified positions through the GI input display.
Applies as from SW 4.4
