SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
Remedy
Determine the SGE involved and the associated hardware signal and
investigate the situation. There may be contact problems at the sensor
(e.g. poor contact) or there were too many switching operations. If
necessary, the behavior can be improved by changing the timer setting.
– 1001
Only in the drive: Initialization error of the check timer.
– 1002
The user agreement is not consistent: The status of the user
agreement is, after 2 s has expired, different for both monitoring
channels.
%3 = status of the user agreement, NCK.
%4 = status of the user agreement, drive.
This effect can occur if the user agreement is only set or reset through
one channel.
An additional fault cause is that if the F code 1003 only occurs in one
monitoring channel and then the user agreement is only withdrawn
through one channel. This means that code 1002 is then the result of a
code 1003 only in one channel.

With the user agreement is set, the difference between the newly
determined reference point (NC actual value) after booting (absolute
value encoder) or reference point approach [homing] (distance-coded
or incremental measuring system) and the safe actual position (saved
value + traversing distance) is greater than the reference tolerance MD
36944/p9544. In this case, the user agreement is withdrawn.
Remedy
Check the mechanical system of the axis – it is possible that the axis
was moved when powered-down and the actual value last saved by the
control no longer corresponds with the new value the next time the
system is booted. It is also possible that the tolerance window for the
check has been set too narrow. The cause should be determined and
after checking the actual values the user agreement can be again reset
after an NCK-RESET.
– 1004
Violated plausibility, user agreement
S Although the user agreement was already set, an attempt
was made to set it again.
S The user agreement is set although the axis has still not
been referenced.
– 1005
When activating the SGEs test stop selection, the shutdown path test
cannot be carried-out because the pulses have already been cancelled.
Remedy
Check the starting conditions for carrying-out the test and if required,
correct. In the commissioning phase, it is also possible that there is
incorrect parameterization (or wiring) for the feedback signal regarding
pulse cancellation (MD 36975).
