SINUMERIK 840C / SIMODRIVE 611–D (DA)
2057* Emergency retraction triggered Reset key
Cyclic in servo cycle, when LINK ON is set for the following spindle (from servo).
Machining interrupted, interlocking of NC START; Mode Group Ready cancelled
The threshold MD “Emergency retraction threshold” programmed for synchronism monitoring has been exceeded
and emergency retraction triggered.
Prerequisite: Enable with PLC interface signal “Emergency retraction enabled”.
Check the drives; check the speed and acceleration limit values of the following spindle; check the emergency
retraction threshold; check the link factors.
Applies as from SW 3
2058* Overlay of following axis not enabled Acknowledgement key
When path for following axis defined (NCK).
Setpoint is not output, i.e. the overlay is not executed.
Overlaid offset of the following spindle although the PLC interface signal “Enable FA overlay” is not set.
Traverse a following axis with fictitious leading axis or set PLC interface signal “Enable FA overlay”.
Applies as from SW 3
2059* Speed limit exceeded Acknowledgement key
Cyclic in servo cycle, when LINK ON is set for following spindle (from servo)
S No reaction
S Machining is not interrupted
The speed of the following spindle is limited to the programmed maximum value; the setpoint determined by the
compensatory controller is not included in the calculation.
The maximum value programmed for the following spindle has been exceeded. Synchronism is at risk
S Reduce feedrate or speed of leading spindles
S Check the speed limit value
S Check the link factors
Applies as from SW 3
2060* Acceleration limit exceeded Acknowledgement key
Cyclic in servo cycle, when LINK ON is set for the following spindle and MD bit “Suppress acceleration limitation”
(MD 526*) is not set (from servo).
S No reaction
S Machining is not interrupted
Interface signal “Acceleration limitation synchronous” is set, spindle continues to travel at maximum acceleration;
any suppressed TSW are traversed afterwards. If interface signal “Acceleration limitation synchronous” is not set,
suppressed partial setpoints are not traversed. The setpoint determined by the compensatory controller is not
included in the calculations.
Maximum value programmed for the following spindle has been exceeded. Synchronism is at risk.
S Reduce the acceleration of the leading spindles
S Check the acceleration limit value
S Check the link factors
Applies as from SW 3
