Remedy: Please inform the authorized personnel/service department. Avoid dual assignment of the
setpoint by correcting 30110 $MA_CTRLOUT_MODULE_NR. Also check the selected
bus type $MA_CTROUT_SEGMENT_NR.
Program Con- Switch control OFF - ON.
tinuation:
26019
Axis %1 encoder %2 measurement not possible with this controller module
Parameters: %1 = NC axis number
%2 = Encoder number
Definitions: If the MD $MN_DRIVE_DIAGNOSIS[8] contains a value not equal to zero, then the con-
trol has found at least one control module which does not support measuring. Measuring
was programmed from the part program for the associated axis.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: If possible, modify the measuring motion such that the axis concerned does not have to
travel; do not program this axis in the MEAS block again. However, it is then no longer
possible to query a measured value for this axis. Otherwise, exchange the controller mod-
ule for one that supports measuring. See MD $MN_DRIVE_DIAGNOSIS[8].
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26020
Axis %1 encoder %2 hardware fault %3 during encoder initialization
Parameters: %1 = Axis name, spindle number
%2 = Encoder number
%3 = Error fine coding
Definitions: Error during initialization of encoder (refer to additional information for absolute encoder
interface from error fine coding).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Please inform the authorized personnel/service department. Rectify hardware error,
replace encoder if necessary. Make sure that an appropriate control module supporting
this function is available with EnDat or SSI absolute encoders.
Bit nos. and their significance:
Bit 0: Lighting failed
Bit 1: Signal amplitude too small
Bit 2: Position value incorrect
Bit 3: Overvoltage
Bit 4: Undervoltage
Bit 5: Overcurrent
