Parker DC590+ Plus Drive

Parker DC590+ Plus Drive Fault Codes:

Fault Code and MeaningCause and Remedy
OVERSPEED

Motor overspeed – the speed feedback signal has exceeded 125% of rated speed.
Cause:

Badly adjusted speed loop (alarm only operates with encoder or armature volts feedback selected).



Remedy:

  • Check speed loop tuning.

  • Note: Alarm time delay is 50 milliseconds.
MISSING PULSE

A missing pulse from the 6-pulse armature current waveform.
Cause:

Firing plug failure or Connection failure.

Note: This trip is only enabled when motor loading exceeds 1.5 times the DISCONTINUOUS parameter value.



Remedy:

  • Check firing circuit connector problems.

  • We recommend fusing the armature circuit if regenerative operation is intended.

  • Note: Alarm time delay is 60 seconds.
FIELD OVER I

The motor field current has exceeded 120% of the calibrated value.
Cause:

External field has incorrect supply phases applied.



Remedy:

  • Check external field supply phases.

  • Note: Alarm only operates with field current control mode selected.
HEATSINK TRIP

The Drive heatsink temperature is too high.
Cause:

The ambient air temperature is too high; Poor ventilation or spacing between Drives; Blocked ventilation slots; Clogged air filters; Excessive armature current.



Remedy:

  • Check for fan failure or wrong rotation.

  • Check fuse on power board.

  • Clean air filters and ventilation slots.

  • Check nominal armature current against calibration.

  • Allow the stack to cool in order to re-start the Drive.
THERMISTOR

The motor temperature is too high.
Cause:

Inadequate ventilation; Blower failure; Excessive armature current.



Remedy:

  • Check blower direction and air filters.

  • Check nominal armature current on nameplate against current calibration.

  • Allow the motor to cool in order to re-start the Drive.
OVER VOLTS (VA)

Motor armature voltage has exceeded 120% of rated volts.
Cause:

Loose armature connection; Badly adjusted field voltage setting; Badly adjusted field current loop; Badly adjusted field-weakening bemf loop; Badly adjusted speed loop.



Remedy:

  • Check armature connections.

  • Adjust relevant loops (field voltage, field current, bemf, speed).
SPEED FEEDBACK

Difference between speed feedback and armature voltage feedback is greater than SPDFBK ALM LEVEL.
Cause:

Analog tacho feedback polarity incorrect; ENCODER SIGN parameter polarity incorrect; Disconnection of wiring (including fibre optics); Tachogenerator failure/coupling failure.



Remedy:

  • Check wiring and polarity (terminals G3 and G4).

  • Check fibre optic cables.

  • Check tachogenerator and coupling.

  • Ensure armature voltage calibration is reduced when running at reduced field currents.
ENCODER FAILED

No speed feedback signal.
Cause:

SPEED FBK SELECT parameter is set to ENCODER but an optional Encoder board is not fitted; Damaged fibre optic cable.



Remedy:

  • Check fibre optic cable for damage, bend radius, operating length.

  • Check cable and connections on wire-ended encoder.
FIELD FAIL

Field current is less than 6% (Current Control) or 50mA (Voltage Control).
Cause:

Open circuit motor field; Faulty operation of field controller; Missing 3-phase supply for synchronization.



Remedy:

  • Check connection and measure field resistance.

  • Check connections FL1 & FL2 for line-to-line voltage.

  • For permanent magnet motors, set FIELD ENABLE parameter to DISABLED.
3-PHASE FAILED

3-phase supply failure.
Cause:

Total failure of supply or missing phase; Blown fuses (thyristor stack or power chassis).



Remedy:

  • Check supply to the controller.

  • Check high-speed thyristor stack protection fuses.

  • Check mains voltage of the Drive (wrong unit/controller voltage).
PHASE LOCK

Supply frequency is outside limits 45 – 65Hz.
Cause:

Supply frequency fault; Synchronization errors caused by distorted supply.



Remedy:

  • Check supply frequency.
5703 RCV ERROR

Invalid data received via P3 port from another Drive.
Cause:

Communication error.



Remedy:

  • Note: Alarm only operates when MODE parameter is set to 5703 SLAVE.
STALL TRIP

Motor stationary, current exceeded STALL THRESHOLD for longer than STALL TRIP DELAY.
Cause:

Mechanical stall or load issue.



Remedy:

  • Check motor load.

  • Note: Alarm only operates when the STALL TRIP parameter is enabled.
OVER I TRIP

Current feedback value has exceeded 280% of rated current.
Cause:

Motor armature windings failure; Badly tuned current loop; Faulty Drive.



Remedy:

  • Check insulation resistance.

  • Check current loop tuning.

  • Refer to Parker SSD Drives for faulty drive.
ACCTS FAILED

AC current transformer plug connection to Drive power board missing.
Cause:

Plug disconnected; Load imbalance (Frame 5).



Remedy:

  • Check armature current transformer plug for correct installation.
AUTOTUNE ERROR

Error encountered during Autotune process.
Cause:

Motor shaft rotating; Open-circuit wiring; Discontinuous current boundary too high; Large supply imbalance; Hardware fault.



Remedy:

  • Ensure motor shaft is stationary.

  • Check drive to armature wiring.

  • Check supply voltage balance.
AUTOTUNE ABORT

The Autotune sequence has been aborted.
Cause:

Coast Stop/Program Stop/Enable disabled; AUTOTUNE parameter reset; Timeout (2 mins).



Remedy:

  • Check terminal inputs during Autotune.

  • Restart Autotune sequence.
SEQ PRE READY

Coding not present.
Cause:

Hardware configuration issue.



Remedy:

  • Replace power board or chassis.
CONTACTOR DELAY

The internal auxiliary 3-phase contactor failed to close.
Cause:

Calibration issue.



Remedy:

  • Check the position of the Calibration Scaling Switch.
EXTERNAL TRIP

Customer alarm! Trip operates if input open or high impedance.
Cause:

Device not wired to drive or device open circuited.



Remedy:

  • Check C1 to C2 connections to drive.

  • Connect C1 to C2 if customer device not fitted.
REMOTE TRIP

Remote Trip flag set.
Cause:

REM. SEQUENCE parameter Remote Trip flag set to zero.



Remedy:

  • Check Remote Sequence parameters.
ENABLE LOW

Local Mode run with Enable input low.
Cause:

Enable input is low while trying to run in Local Mode.



Remedy:

Remedy:

  • Contact Parker SSD Drives.
COMMS TIMEOUT

Remote comms timeout.
Cause:

Communication interruption.



Remedy:

CONFIG ENABLED

The drive was requested to start whilst in Configuration mode.
Cause:

Drive is in Configuration mode.



Remedy:

CALIBRATION FAIL

Signal calibration fault.
Cause:

Hardware failure suspected.



Remedy:

  • Power unit off and on.

  • If problem persists, contact Parker SSD Drives.
