  • Check motor circuit (delta connection, star connection).

  • Check setting of the motor data.


2320
Short circuit or earth leakage on motor side

Cause: Classification: Error



Remedy:

  • Check motor cable.

  • Check the length of the motor cable.

  • Use shorter or lower-capacitance motor cable.


2340
CiA: Short circuit (inside the device)

Cause: Classification: Error



Remedy:

  • Check motor cable for short circuit.


2350
CiA: i²*t overload (thermal state)

Cause: Classification: Error



Remedy:

  • Check drive sizing.

  • Check machine/driven mechanics for excessive load.

  • Check setting of the motor data.

  • Reduce values for slip compensation (0x2B09:001, 0x2B09:002) and oscillation damping (0x2B0A:001, 0x2B0A:002).


2382
Error – device utilization (Ixt) too high

Cause: Classification: Error



Remedy:

  • Check drive sizing.

  • In case of high mass inertias, reduce maximum overload current of the inverter (0x6073) to 150 %.


2383
Warning – device utilization (Ixt) too high

Cause: Classification: Warning



Remedy:

  • Check drive sizing.


3120
Mains phase fault

Cause: Classification: Error



Remedy:

  • Check mains connection wiring.

  • Check fuses.


3210
Error – DC bus overvoltage

Cause: Classification: Error



Remedy:

  • Reduce dynamic performance of the load profile.

  • Check mains voltage.

  • Check settings for the brake energy management.


3211
Warning: DC-bus overvoltage

Cause: Classification: Warning



Remedy:

  • (See Error 3210 for typical checks)


3220
Error – DC-bus undervoltage

Cause: Classification: Trouble



Remedy:

  • Check mains voltage.

  • Check fuses.

  • Check DC-bus voltage (0x2D87).

  • Check mains settings.


3221
Warning: DC bus undervoltage

Cause: Classification: Warning



Remedy:

  • (See Error 3220 for typical checks)


3222
DC-bus voltage too low for switch-on

Cause: Classification: Warning



Remedy:

  • Check mains voltage.

  • Check fuses.

  • Check mains settings.


4210
Error – power section overtemperature

Cause: Classification: Error



Remedy:

  • Check mains voltage.

  • Ensure sufficient cooling of the device (display of heatsink temperature in 0x2D84:001).

  • Clean fan and ventilation slots. If required, replace fan.

  • Reduce switching frequency (0x2939).


4281
Warning – heatsink fan

Cause: Classification: Warning



Remedy:

  • Clean fan and ventilation slots. If required, replace fan. The fans can be unlocked via locking hooks and can then be removed.


4310
Motor overtemperature

Cause: Classification: Error



Remedy:

  • Check drive sizing.

  • Check motor temperature sensor and wiring at X105/T1+T2 or X109/T1+T2.


5112
24 V supply critical

Cause: Classification: Warning



Remedy:

  • Check optional external auxiliary supply on X100.1/24E.1, if connected.

  • Check mains voltage.


5180
24 V supply overload

Cause: Classification: Warning



Remedy:

  • Check 24 V output and digital outputs for earth fault or overload.


6280
Trigger/functions connected incorrectly

Cause: Classification: Trouble



Remedy:

  • Check and correct the assignment of the triggers to the functions.

  • In network control, the two functions “Inverter enable” (0x2631:001) and “Start” (0x2631:002) can also be set to “Constant TRUE [1]” to start the motor.


7180
Motor overcurrent

Cause: Classification: Error



Remedy:

  • Check motor load.

  • Check drive sizing.

  • Adapt set error threshold (0x2D46:001).


FF06

Cause: Classification: Error



Remedy:

  • Adapt the maximum motor speed (0x6080) and the error threshold (0x2D44:001).


FF37
Automatic start disabled

Cause: Classification: Error



Remedy:

  • Deactivate start command and reset error.
