Program Continuation:

Axis %1 encoder %2 hardware fault %3 during encoder initialization

%1 = Axis name, spindle number %2 = Encoder number %3 = Error fine coding

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).

-    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.

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

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


Bit 9: C/D track error on encoder ERN1387 or EQN encoder connected or incorrectly configured (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 expansion

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 system connector has been plugged in and prior to disabling the Parking Axis. After the Parking 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.

Switch control OFF - ON.
