Alarm, error, and system messages
10.5 Error messages
E74 Maximum values of internal physical variables reached
The error occurs if the variables in the mathematical calculation model exceed the following
limits:
psi_model
psip_model
psi_ofs_model
In this case, the calculation model has oscillated uncontrollably and all movements must be
terminated.
Procedure in the event of an error
● Set the control bits "move," "move_SkA," and "AS_ON" to zero.
● You can use control bit "reset_mdl" to reset the mathematical calculation model only if error
E74 occurs.
Error bit:
Error type: Error
Remedy:
E75 Monitoring of the magnitude of the skew oscillation
The error is set if (|psi_modell|>P314) or (|psi_kam|>P314) applies. If the error is set, skew
damping must be deactivated via "AS_ON"=0.
The error is reset if the absolute values of the two angles stated above are below value P317
for duration P318.
Error bit:
Error type: Error
E76 Error in parameterization of position limits TLS
The condition in Chapter TLS inching and go to zero positions (Page 356) was not considered
in the parameterization. Therefore only a procedure with mode_comm = 1 is possible.

Error word 2, bit 5
1. Eliminate the causes:
– Incorrect parameterization
– Erroneous input signals
– Control errors
(e.g. control bits spreader_bit0 and spreader_bit1)
2. Acknowledge the error with control bit reset_mdl
3. Check the skew drive
