Remedy: The current set in MD1019: $MD_CURRENT_ROTORPOS_IDENT (rotor position identi-
fication current) that is not smaller the permissible minimum value (40% for non-Siemens
synchronous linear motor (SLM)).
Possibly, a larger power section must be used.
If allowed with the motor used, hide the error by setting bit 5 in MD 1012:
$MD_FUNCTION_SWITCH (function switch).
Caution: Motors with a low saturation response (e.g. 1FN3 linear motors) might react to
very low identification currents with misorientation. This can lead to uncontrolled move-
ments.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
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 permissi-
ble. The signal number range is between 0 and 25.
Reactions: - 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 num-
ber.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
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.
Reactions: - 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 Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
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
$MD_CURRENT_SMOOTH_HYSTERESIS (hysteresis of the speed-dependent M set-
