300854 Axis %1 drive %2 signal number of var. signaling function invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The signal number for the output of the corresponding signaling function is not permissi-
ble. The signal number range is between 0 and 25.
Reactions: - Interface signals are set.
- Alarm display.
Remedy: Enter the correct signal number.
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
300855 Axis %1 drive %2 voltage/frequency mode: motor is turning
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The motor did not come to a standstill when the voltage/frequency mode was activated.
Reactions: - Interface signals are set.
- Alarm display.
Remedy: Stop the motor before activating the voltage/frequency mode.
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
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 (deactiva-
tion threshold for generator axis).
Reactions: - Interface signals are set.
- Alarm display.
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 con-
trol) or
• Modify MD 1633: $MD_LINK_VOLTAGE_GEN_OFF (voltage range for generator con-
trol) or
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
300859 Axis %1 drive %2 generator mode: response voltage > monitoring threshold
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator
axis) is greater than MD1630: $MD_LINK_VOLTAGE_MON_THRESHOLD (response
threshold for DC link monitoring).
Reactions: - Interface signals are set.
- Alarm display.
Remedy: Please inform the authorized personnel/service department.
