With the selected setting of MD1466, the induced voltage is too small in the lower speed
range in order to be able to guarantee safe, sensorless operation. With the specified
speed, the induced voltage must at least reach 20 V (phase-to-phase, effective).
- 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 following must be ensured:
Rotary machine : MD1466 > 20000 / MD1114
Linear machine : MD1466 > 693 / MD1114
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 data backup and reboot required
%1 = NC axis number
%2 = Drive number
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 param-
eters, 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).
- 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 newly calculated data must be saved (Softkey: SAVE). The new parameters will
become effective during the next boot procedure!
Switch control OFF - ON.
Axis %1 drive %2 parameterization error in speed control adaption
%1 = NC axis number
%2 = Drive number
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).
- Interface signals are set.
- Alarm display.
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).
Alarm display showing cause of alarm disappears. No further operator action necessary.
