Overview of Alarms
Bit 6: Battery change necessary
Bit 7: Control check error, Note: SW 4.2 and higher, synchronous linear motor
Bit 8: EnDat encoder, incorrect overlapping, Note: SW 4.2 and higher, synchronous linear
motor
Bit 9: C/D track error on encoder ERN1387 or EQN encoder connected or incorrectly con-
figured (not on EQN, MD 1011)
Bit 10: Log cannot be aborted or old hardware
Bit 11: SSI level detected on data line or no encoder connected or incorrect encoder cable
(ERN instead of EQN)
Bit 12: Timeout while reading measuring value
Bit 13: CRC error
Bit 14: Wrong IPU submodule for direct measuring signal, Note: Only with 611D expan-
sion
Bit 15: Encoder faulty
Note: If an axis that is connected to the second measuring system of a controller module
611D only, is driven by an absolute encoder, the axis with the first measuring system of
this controller module will have to be switched to Parking Axis, after the measuring sys-
tem connector has been plugged in and prior to disabling the Parking Axis. After the Park-
ing Axis of the first measuring system has been disabled, all measuring systems of the
controller module will be initialized. The Parking Axis of the second measuring system
can then be disabled without errors.
Program Con- Switch control OFF - ON.
tinuation:
26022
Axis %1 encoder %2 measurement with simulated encoder not possible
Parameters: %1 = NC axis number
%2 = Encoder number
Definitions: Alarm occurs on the control when a measurement was made without the encoder hard-
ware (simulated encoder).
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Please inform the authorized personnel/service department. If possible, modify the mea-
suring 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.
• Ensure that measurement is not taking place with simulated encoders (MD
$MA_ENC_TYPE).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26024
Axis %1 machine data %2 value changed
Parameters: %1 = Axis name, spindle number
%2 = String: MD identifier
Definitions: Machine data contains an invalid value and therefore has been changed by the software.
Reactions: - Alarm display.
Remedy: Check MD.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
2-388
