300865 Axis %1 drive %2 measurement of DC link voltage not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: If the fixed voltage MD 1161: $MD_FIXED_LINK_VOLTAGE(DC link fixed voltage) = 0, no DC link
measurement is possible because the hardware version is wrong.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Enter a value greater than 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.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
300875 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.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Set the same fixed voltage (MD 1161) on
all module axes.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
300888 Axis %1 drive %2 parameterization error in current control adaption
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The upper current limit in MD 1181: $MD_CURRCTRL_ADAPT_CURRENT_2 (upper adaption
current limit) is less than the lower current limit in MD 1180: $MD_CURRCTRL_ADAPT_CURRENT_1
(lower adaption current limit).
Reaction: Interface signals are set.
Alarm display.
Remedy: Modify MD 1181: $MD_CURRCTRL_ADAPT_CURRENT_2 (upper adaption current limit) and MD
1180: $MD_CURRCTRL_ADAPT_CURRENT_1 (lower adaption current limit).
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
