E8042 Both travel range limit switches activated
Cause
Due to incorrect mounting, axis activates both travel
range limit switches simultaneously
Travel range limit switches were incorrectly
connected
Switching logic of travel range limit switches does
not correspond to realized wiring
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
The compliance with the allowed travel range of linear axes is monitored
on the hardware side via two travel range limit switches. When the travel
range has been exceeded, one of the two limit switches is activated, if the
limit switches were correctly mounted.
The warning E8042 is generated, if
•
the controller detects that both travel range limit switches have been
simultaneously activated and
•
exceeding the travel range is handled as a fatal warning (setting in
P-0-0090, Travel range limit parameter).
Note:
Unless the cause of E8042 has not been removed the
controller does not accept any command value!
Remedy
Mount travel range limit switches in such a way that they
are activated shortly before axis end position is reached.
Make sure the braking distance is sufficient
Connect travel range limit switches correctly; check
compliance with switching logic set in P-0-0090, Travel
range limit parameter
Check switching logic with regard to realized wiring,
adjust it in P-0-0090, Travel range limit parameter, if
necessary
