Sinumerik Alarm 300775 Axis %1 drive %2 fixed link voltage of axes differ


Sinumerik Alarm 300775 Axis %1 drive %2 fixed link voltage of axes differ

Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
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. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).

Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.

Remedy:
Please inform the authorized personnel/service department. Set the same fixed voltage (MD 1161) on all module axes. $MD_FIXED_LINK_VOLTAGE (DC link fixed voltage) has been found for axes of a drive module.

Program Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
