Overview of Alarms
SIMODRIVE alarms
300861 Axis %1 drive %2 generator mode: minimum axis speed > max. motor
speed
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD1635: $MD_GEN_AXIS_MIN_SPEED $MD_GEN_AXIS_MIN_SPEED (minimum
generator axis speed) is greater than the value in MD1146: $MD_MOTOR_MAX_ALLOWED_SPEED
(maximum motor speed).
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Modify MD 1635: $MD_GEN_AXIS_MIN_SPEED generator axis) or
- Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed).
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
300862 Axis %1 drive %2 emergency retraction mode/generator mode already
active
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Emergency retraction or generator mode already active.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Check parameterization/machine data.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
300863 Axis %1 drive %2 emergency retraction mode/generator mode invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Value specified by the NC via a G command must be in the range 0 to 7.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Check parameterization (G command in
the NC).
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
300864 Axis %1 drive %2 emergency retraction mode/generator mode not
possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Emergency retraction/Generator operation is only possible with an active DC link measurement (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.
Reaction: Interface signals are set.
Alarm display.
Remedy: 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.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
