Parker TWIN-N and SPD-N Servo Drive

Parker TWIN-N and SPD-N Servo Drive Fault Codes:

Fault Code and MeaningCause and Remedy
0

No alarm
Cause: Normal operation.


Remedy:

  • No action required.
1

DC circuit overvoltage
Cause: Voltage in the DC circuit has exceeded limits.


Remedy:

  • Check the three-phase power line (max 480V + 10%).

  • Check the break circuit and the braking resistor.
2

DC circuit undervoltage
Cause: Voltage in the DC circuit is too low.


Remedy:

  • Check the three-phase power line.
3

Overcurrent
Cause: Excessive current detected.


Remedy:

  • Check the motor connections.

  • Check for any phase-phase or phase-ground short-circuits.

  • Check the motor data.
4

FBK error (resolver or encoder)
Cause: Feedback loop signal failure.


Remedy:

  • Check the connections of the speed loop.

  • Check the connectors on both sides (drive-motor).

  • Check the feedback parameters.
5

PTC motor alarm
Cause: Motor temperature sensor issue or overheat.


Remedy:

  • Check the PTC connection cable.

  • Check the parameters Pr33 (Inom) and Pr19 (Ipeak).
6

Power module overtemperature
Cause: Thermal limit reached in power module.


Remedy:

  • Check the cooling fans and for any restrictions to air flow.

  • Check the braking cycle.

  • Check the ambient temperature in the electric cabinet where the drive is installed.

  • Check the ambient temperature outside the cabinet.
7

External alarm
Cause: Triggered by external input.


Remedy:

  • Depends on the application (b41.7 – see Pico-PLC program).
8

Auxiliary alarm
Cause: Triggered by auxiliary condition.


Remedy:

  • Depends on the application (b41.8 – see Pico-PLC program).
10 (*)

PLC check sum
Cause: Data integrity error in PLC program.


Remedy:

  • Set and save default parameters.

  • Switch off and on again the drive.

  • Repeat programming.



(*) Reset only after default values have been loaded and saved.
11 (*)

Parameter check sum
Cause: Data integrity error in parameters.


Remedy:

  • Set and save default parameters.

  • Switch off and on again the drive.

  • Repeat programming.



(*) Reset only after default values have been loaded and saved.
14

Overload braking resistor
Cause: Braking resistor duty cycle exceeded.


Remedy:

  • Check the braking cycle.
15

Default parameters
Cause: Parameters need reset.


Remedy:

  • Set and save default parameters.

  • Switch off and on again the drive.

  • Repeat programming.
17 (**)

Hardware broken
Cause: Internal hardware failure.


Remedy:

  • Internal damage, send to repair.



(**) Can be only reset at the next power on.
22

Ambient over temperature
Cause: The ambient temperature in the electric cabinet is excessive (>45°C).


Remedy:

  • Check the cooling fans.

  • Check for any restrictions to air flow.
24

Braking dynamic protection
Cause: Short-circuit in braking resistance.


Remedy:

  • If an external braking resistor is connected to the drive, check the resistor status and wiring.
25 (**)

Speed loop FBK initialization error
Cause: Feedback initialization failure.


Remedy:

  • Check the speed FBK settings.

  • Check the speed FBK connection.



(**) Can be only reset at the next power on.
30

EEPROM not recognized
Cause: Memory hardware failure.


Remedy:

  • Internal damage, send to repair.
TripP.x (where x is a number)

Hardware broken
Cause: Internal hardware failure.


Remedy:

  • Internal damage, send to repair.
I²T

Current limit (I²T)
Cause: The drive goes in I²T mode due to an overload (the current required is more than the current that can be supplied).

(Display shows decimal points on all characters)


Remedy:

  • Check the wiring between drive and motor (there should be no inverted phases).

  • Take special care with motors where the connector is replaced by a terminal block: it’s easy to make a mistake. Adhere strictly to the wiring diagrams.

  • Check mechanical dimensioning.
