The value of machine data MD 1210: $MD_CURRENT_FILTER_1_SUPPR_FREQ
(blocking frequency of current setpoint filter 1) or MD 1213:
$MD_CURRENT_FILTER_2_SUPPR_FREQ (blocking frequency of current setpoint filter
2) or MD 1216: $MD_CURRENT_FILTER_3_SUPPR_FREQ (blocking frequency of cur-
rent setpoint filter 3) or MD 1219: $MD_CURRENT_FILTER_4_SUPPR_FREQ (blocking
frequency of current setpoint filter 4) must be less than the reciprocal value of two current
controller cycles MD 1000: $MD_CURRCTRL_CYCLE_TIME (current controller cycle).
(1/2*MD 1000*31.25 microsec)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 rotor position identification current less than minimal value
%1 = NC axis number
%2 = Drive number
The current set in MD1019: $MD_CURRENT_ROTORPOS_IDENT (rotor position identifi-
cation current) that is smaller than the minimum value permissible for the motor.
- 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.
The current set in MD1019: $MD_CURRENT_ROTORPOS_IDENT (rotor position identifi-
cation 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.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 signal number of var. signaling function invalid
%1 = NC axis number
%2 = Drive number
The signal number for the output of the corresponding signaling function is not permissi-
ble. The signal number range is between 0 and 25.
- 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.
Please inform the authorized personnel/service department. Enter the correct signal num-
ber.
Clear alarm with the RESET key in all channels. Restart part program.
