Sinumerik Alarm 300858 Axis %1 drive %2 generator mode: response voltage > switch-off threshold


Sinumerik Alarm 300858 Axis %1 drive %2 generator mode: response voltage > switch-off threshold

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

Definitions:
The sum of the values in MD1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator axis) + MD1632: $MD_LINK_VOLTAGE_GEN_HYST (voltage range for generator control) is greater than MD1633: $MD_LINK_VOLTAGE_GEN_OFF (deactivation threshold for generator axis).

Reactions:
– Alarm display.
– Interface signals are set.

Remedy:
Please inform the authorized personnel/service department. Modify drive machine data
• Modify MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator axis) or
• Modify MD 1632: $MD_LINK_VOLTAGE_GEN_HYST (voltage range for generator control) or
• Modify MD 1633: $MD_LINK_VOLTAGE_GEN_OFF (voltage range for generator control) or

Program Continuation:
Alarm display showing cause of alarm disappears. No further operator action
