Axis %1 drive %2 emergency retraction mode/generator mode not possible

%1 = NC axis number %2 = Drive number

Emergency retraction/Generator operation is only possible with an active DC link measurement (MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage = 0). In an old hardware version, no DC link measurement is possible and therefore the error message 300765 might appear in addition if MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) is set to 0 in an old hardware version.

-    Interface signals are set.

-    Alarm display.

Please inform the authorized personnel/service department. Enter the value zero in the machine data MD 1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage), or order a new hardware version of the control module.

Alarm display showing cause of alarm disappears. No further operator action necessary.
