Please inform the authorized personnel/service department. Check parameterization (G
command in the NC).
Alarm display showing cause of alarm disappears. No further operator action necessary.
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 mea-
surement (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.
Axis %1 drive %2 measurement of DC link voltage not possible
%1 = NC axis number
%2 = Drive number
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.
- Interface signals are set.
- Alarm display.
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 volt-
age), or order a new hardware version of the control module.
Alarm display showing cause of alarm disappears. No further operator action necessary.
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 mea-
sured 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.
- Interface signals are set.
- Alarm display.
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 necessary.
Axis %1 drive %2 parameterization error in current control adaption
%1 = NC axis number
%2 = Drive number
