Alarm, error, and system messages
10.5 Error messages
E69 Failure rate of camera signal too large for skew damping
Error E69 is set if the bit "CAMERA_OK" was equal to 1 for a time period P312 (time window
camera fault detection TLS) in a lower percentage of SIMOTION cycles than specified in P313
(camera fault trigger threshold TLS).
The maximum value for P312 depends on the cycle time in which block DCC_SCTLS2 is
programmed. A total of 6000 cycles are possible. This is 60 seconds with a cycle time of 0.01
seconds, and 144 seconds with a cycle time of 0.024 seconds.
There is a risk that the mathematical calculation model is failing to simulate the real oscillation
with sufficient accuracy and that the skew-damping control will actually increase the level of
sway under adverse circumstances. There is no system response to this error.
Procedure in the event of an error
● Deactivate the skew-damping function.
To do this, set control bit "AS_ON" to zero.
Error bit:
Error type: Error
Remedy:
E70 Internal value range overflow
Mechanisms are implemented in the software to prevent the variable range overflows and the
resultant transition to SIMOTION stop.
Possible causes for the error message
● Errors in TLS function parameter settings
● Erroneous input signals
The output signals can supply false values in the event of an error.
Procedure in the event of an error
● Reset the control bits "move" and "move_SkA."
● Do not utilize the skew-damping function again until the cause has been eliminated.
Error bit:
Error type: Error
Remedy:
E71 Maximum values of internal variables reached
A number of physical quantities are limited in the software. The limits are outside the orders of
magnitude typical of cranes.

Eliminate the cause of the impaired camera signal of the SIMOCRANE CenSOR
camera measuring system
Error word 2, bit 1
Eliminate the cause:
● Incorrect parameterization
● Erroneous input signals
