SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
• for e) Correctly set the machine data 840D MD10082: $MN_CTRLOUT_LEAD_TIME
(Offset of the setpoint acceptance instant) with the machine data MD10083:
$MN_CTRLOUT_LEAD_TIME_MAX (Maximum settable offset of the setpoint accep-
tance instant).
• for f) Check MD 1300 $MD_STS_CONFIG.
Switch control OFF - ON.
Axis %1 drive %2 synchronization error of rotor position
%1 = NC axis number
%2 = Drive number
There is a difference of more than 45° electrical between the present rotor position (C/D
track) and the new rotor position as determined by fine synchronization. Faults may have
occurred in the encoder or zero marker signals.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
• Use original Siemens encoder cables (they have a higher degree of screening).
• Check the encoder, encoder cables and screen connection for damage.
• Check the shield connection on the front plate of the controller module (top screw).
• Replace the control module.
• Check MD 1016 $MD_COMMUTATION_ANGLE_OFFSET (commutation angle offset).
Switch control OFF - ON.
Axis %1 drive %2 zero mark monitoring of motor measuring system
%1 = NC axis number
%2 = Drive number
An error was detected in the number of encoder lines counted to modulo (16/10) on cross-
ing of the zero marker. Increments were lost or added.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department.
• Use original Siemens encoder cables (they have a higher degree of screening).
• Check the encoder, encoder cable and shield connection for loose contact or cable
breakage.
• Check the shield connection on the front plate of the controller module (top screw).
• For a gearwheel encoder, check the distance between the gearwheel and the sensor.
