Overview of Alarms
SIMODRIVE alarms
300799 Axis %1 drive %2 data backup and reboot required
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Since drive machine data have been changed, it is necessary to recalculate parameters. This is
initiated by pressing the softkey CALCULATE. After calculating the control parameters, it is necessary
to save the machine data and to reboot.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: The newly calculated data must be saved (Softkey: SAVE). The new parameters will become
effective during the next boot procedure!
Program Switch control OFF - ON.
Continuation:
300850 Axis %1 drive %2 parameterization error in speed control adaption
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The upper adaptation speed MD 1412: $MD_SPEEDCTRL_ADAPTSPEED_2 (upper adaptation
speed) is less than the lower adaptation speed MD 1411: $MD_SPEEDCTRL_ADAPTSPEED_1
(lower adaptation speed).
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Modify MD 1412:
$MD_SPEEDCTRL_ADAPTSPEED_2 (upper adaptation speed) and MD 1411:
$MD_SPEEDCTRL_ADAPTSPEED_1 (lower adaptation speed).
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
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 permissible. The signal
number range is between 0 and 25.
Reaction: Interface signals are set.
Alarm display.
Remedy: Enter the correct signal number.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
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.
Reaction: Interface signals are set.
Alarm display.
Remedy: Stop the motor before activating the voltage/frequency mode.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
