DIAX02 — DDS / DKS / DDC fault codes & diagnostics

Clearing data RAM

The controller is clearing its data RAM during initialization.

Checking parameter memory

The controller checks and may clear the software module EEPROM.

Loading program

Firmware is loading from EPROM into program memory.

Checking hardware

The controller is checking data RAM.

Initializing hardware

Hardware initialization is in progress.

Initializing software

EEPROM data are copied to RAM and checked against limits.

Initializing software: oscillator and feedback

Oscillator functions and feedback codes are being initialized.

Initializing software: DSF data

DSF data are being read.

Initializing SERCOS

SERCOS initialization is in progress.

Watchdog

A missing or defective software module, or a defective processor, is indicated. The graphic shows the two decimal points illuminated with no digit segments. The string '..' is a searchable transcription of that pattern.

Drive ready

Control and power sections are ready; power is on, but drive enable has not been applied.

Drive enable signal

Drive enable is applied and the drive follows the velocity command.

Drive halt

The drive is brought to a controlled stop and remains under control.

Starting lock-out

The power output stage is locked.

Ready for input power

The control section is ready for power-up.

E-STOP (Emergency stop)

Emergency stop is active; the configured error reaction applies.

Park axis command

The controller has received the park-axis command and is deactivated.

Phase 0

The drive is waiting for progression from SERCOS Phase 0 to Phase 1.

Phase 1

The drive is waiting for progression from SERCOS Phase 1 to Phase 2.

Phase 2

Parameters are checked before progression to Communications Phase 3.

Phase 3

Parameters are checked before progression to Communications Phase 4.

Double MST error shutdown

The source states that the master synchronization telegram was absent for two successive SERCOS cycles.

Double MST error shutdown

The source repeats the same heading and description as code 01. The supplied manual labels both 01 and 02 'Double MST error shutdown' and gives the same two-cycle MST description. No MDT correction has been inferred.

Invalid communication phase shutdown

The SERCOS master commanded an invalid communications phase greater than 4.

Error during phase progression

Communications phase progression did not follow the required sequence.

Error during phase regression

Communications phase regression did not return to Phase 0.

Phase progression without ready signal

The SERCOS master attempted a phase change before drive readiness.

Switching to uninitialized operating mode

The activated operating-mode parameter has no operating mode defined.

Drive overtemperature shutdown

Power-stage overtemperature caused drive shutdown after an overtemperature warning.

Motor overtemperature shutdown

Motor temperature exceeded the permitted level and caused shutdown.

Bleeder overtemperature shutdown

Excessive continuous regenerative power caused bleeder overtemperature shutdown.

Motor encoder failure

Motor-encoder signals are outside their monitored tolerance range.

Overcurrent

A phase current exceeded 1.5 times the unit rated current.

Overvoltage error

DC-link voltage exceeded the permitted level and drive torque was disabled.

Undervoltage error

DC-link voltage fell below the monitored minimum level.

Excessive deviation

The drive could not follow the command value.

Travel limit switch is exceeded

A command would move the axis beyond its permitted travel range.

Command error

A collective error occurred during command execution; the detailed diagnostic is in S-0-0095. This heading is in the H1 section, but its paragraph says the collective diagnostic appears on H2 (32, flashing). This internal inconsistency is retained; the file does not contain referenced section 2.3.

External power supply error

The external supply for optional isolated inputs and outputs is above its permitted level.

Error in internal software synchronization

Communication between the drive processor and SERCOS interface module is faulty.

Invalid reference cam position

The reference cam position relative to the motor-encoder zero point is outside its permitted range.

Excessive actual position difference

The two encoder position values differ by more than the configured monitoring window.

Excessive position command difference

Successive position commands demand velocity at or beyond the configured bipolar velocity limit.

External encoder failure: signals too small

External measuring-system signal amplitudes are below the permitted minimum.

Invalid feedback data --> Phase 2

Motor-encoder failure during cyclic operation has left invalid feedback data.

Travel limit switch detected

A travel limit switch was detected and the affected drive supply shut down.

External encoder failure: quadrant error

A hardware error was detected in the external sine-signal position interface.

External encoder failure: frequency limit exceeded

The external measuring-system interface maximum input frequency was exceeded.

Error in detecting the marker of the external encoder

External-encoder marker detection failed.

Low absolute encoder battery voltage

The absolute-encoder backup battery voltage fell below 2.8 V.

Master encoder failure

Master-encoder signals moved outside the monitored tolerance range.

Drive overtemperature warning

The drive-controller heatsink reached its maximum permitted temperature.

Motor overtemperature warning

The motor exceeded its permitted temperature.

Bleeder overtemperature warning

Regenerative operation entered the bleeder overload range.

Bridge fuse

Power-transistor bridge current exceeded twice the unit rated current.

Overcurrent: short to ground

The phase-current sum indicates an earth fault.

Erroneous internal hardware synchronization

The monitored pulse-width modulator synchronization is faulty.

Brake error

Holding-brake current is outside its permissible range.

±15 V error

The controller detected a fault in the ±15 V supply.

+24 V error

The controller detected a fault in the +24 V supply.

±10 V error

The current-sensor supply voltage is faulty.

+8 V error

The encoder-system supply voltage is faulty.

Power supply to driver stage

The driver-stage voltage supply is faulty.

Pattern data transmission time invalid

Pattern data are not sent synchronously with the lead-axis position.

Number of transmitted pattern data invalid

Too few or no pattern data were transmitted.

Absolute encoder error

The encoder position at power-up differs from the stored position beyond the configured window.

Velocity loop error

Velocity feedback did not approach the commanded velocity within the monitored interval.

Program RAM error

A program-memory check failed during initialization.

Data RAM error

A data-memory check failed during initialization.

Error reading drive data

Drive EEPROM data could not be read during initialization.

Drive data invalid

The drive data are invalid; the source identifies a hardware error.

Error while writing to parameter memory

The programming-module parameter memory did not accept data.

Parameter data invalid

One or more software-module parameters were invalid during initialization.

Error reading motor data

Motor-feedback memory data could not be read.

Motor data invalid

Motor data are invalid; the source identifies defective motor feedback.

Error while writing motor data

Writing data to the motor feedback failed.

Configuration error

Software and hardware configuration mismatch, or an absent, misplaced or defective plug-in module, is indicated.

Absolute encoder not calibrated

Absolute-encoder reference-position or counting-direction data could not be read.

DLC watchdog error, no communication with DLC possible

The DLC processor is out of synchronization with the drive-controller processors.

Output power

The decimal point indicates optical output power: lit means high and unlit means low. This is the decimal-point optical-power indicator, not a fault code. Its on/off state carries the meaning.
