Sinumerik Alarm 300875 Axis %1 drive %2 fixed link voltage of axes differ
%1 = NC axis number
%2 = Drive number
An unequal fixed voltage MD1161: $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) has been found for axes of a drive module. Since a fixed voltage <> 0 replaces the measured DC link voltage value, but the DC link voltage value is measured only once for all axes of a drive module, the fixed voltage must be identical on all module axes before it is accepted.
– Alarm display.
– Interface signals are set.
Please inform the authorized personnel/service department. Set the same fixed voltage (MD 1161) on all module axes.
Alarm display showing cause of alarm disappears. No further operator action
