Overview of Alarms
SIMODRIVE alarms
300754 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: 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: Please inform the authorized personnel/service department. Enter the correct signal number.
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300755 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: 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: Stop the motor before activating the voltage/frequency mode.
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300756 Axis %1 drive %2 speed hysteresis of setpoint current smoothing invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1246: $MD_CURRENT_SMOOTH_HYSTERESIS (hysteresis of the speed-
dependent M setpoint smoothing) is greater than or equal to the value in MD 1245:
$MD_CURRENT_SMOOTH_SPEED (threshold of the speed-dependent M setpoint smoothing).
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: Please inform the authorized personnel/service department. Check and, if necessary, correct the
torque adaptation factor MD 1246: $MD_CURRENT_SMOOTH_HYSTERESIS (hsyterisis of the
speed-dependent M setpoint smoothing) or MD 1245: $MD_CURRENT_SMOOTH_HYSTERESIS
(threshold of the speed-dependent M setpoint smoothing). $MD_CURRENT_SMOOTH_SPEED.
Program Clear alarm with the RESET key in all channels. Restart part program.
