27001 Axis %1 error in a monitoring channel, Code%2, values: NCK%3, drive %4
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 test 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
● Although the user agreement was already set, an attempt was made to set it again.
● The user agreement is set although the axis has still not been referenced.
Remedy
Violated plausibility, user agreement
1005
When activating the SGEs test stop selection, the switch-off signal path test cannot be carried out because
the pulses have already been cancelled.
Remedy
Check the start 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 can‐
cellation.
1009
After activating the SGE test stop selection, the pulses have still not been cancelled after timer MD36957
$MA_SAFE_PULSE_DIS_CHECK_TIME has elapsed.
Remedy
Check the parameterization for the timer - it is possible that the value has been selected too low.
1011
The internal status "acceptance test status" when using the acceptance test support indicates different states
for the NCK/drive for at least 4 seconds.
Remedy
Acceptance test time expired
1013
NCK user agreement from the PLC-SRAM and NCK user agreement from the NCK machine data are different.
Remedy
Re-establish data consistency using power on.
1014
NCK axis number from the PLC-SRAM and NCK axis number from the boot operation are different.
Remedy
Re-establish data consistency using power on.
1020
Cyclic communications between the NCK and drive no longer functions.
Remedy
Analyze the other fault/error messages. Restart using power on.
1023
Effectiveness test error in the Sensor Module.
Remedy
Check the Sensor Module.
