Hex: 1020
Description: Overvoltage in DC bus
Keypad display: OU
Cause Remedy Severity/response

Braking energy is too high. (DC−bus voltage is higher than set in C0173.)
  • Use braking unit or regenerative module.
  • Check dimensioning of the brake resistance.
Fault ID: 0016
Hex: 0016
Description: I2xt overload
Keypad display: OC6
Cause Remedy Severity/response
  • Frequent and too long acceleration processes with motor overcurrent.
  • Permanent motor overload with Imotor >Irmotor

Check drive dimensioning.
Fault ID: x018
Hex: x018
Description: I2xt overload advance warning
Keypad display: OC8
Cause Remedy Severity/response
  • Frequent and too long acceleration processes with motor overcurrent.
  • Permanent motor overload with Imotor >Irmotor

Check drive dimensioning.
Fault ID: 0015
Hex: 0015
Description: I x t overload
Keypad display: OC5
Cause Remedy Severity/response

Check drive dimensioning.
Fault ID: 0012
Hex: 0012
Description: Motor cable earth fault
Keypad display: OC2
Cause Remedy Severity/response

One of the motor phases has
earth contact.
  • Search for cause of short circuit.
  • Check motor cable.
Fault ID: 0011
Hex: 0011
Description: Short circuit of motor cable
Keypad display: OC1
Cause Remedy Severity/response

Short circuit

Excessive capacitive charging
current in the motor cable.
  • Search for cause of short circuit.

  • Check motor cable.

    Use motor cable which is shorter
    or of lower capacitance.
Fault ID: 9090
Hex: 0x2382
Description: Fault - Device utilization (ixt) too high
Keypad display: Ixt error
Cause Remedy Severity/response

Device utilisation (ixt) too high by frequent and too long acceleration processes.

Check drive sizing. 

  • Reduce the maximum current of the inverter 0x6073 (P324.00). 
  • In case of high mass inertias, reduce maximum current of the inverter 0x6073 (P324.00) to 150 %.

Fault (configurable)

  • The event can only be reset after a blocking time.

Blocking time: 2 s

Setting parameters: 0x2D40:005 (P135.05)
Fault ID: 9040
Hex: 0x2350
Description: CiA: i²xt overload (thermal state)
Keypad display: i2t motor
Cause Remedy Severity/response

Motor thermally overloaded, e. g. by an impermissible continuous current or by frequent or too long acceleration processes.

Check drive sizing.

  • Check machine/driven mechanics for excessive load.
  • Check settings of the motor data.
  • Reduce values for slip compensation 0x2B09:001 (P315.01), 0x2B09:002 (P315.02) and oscillation damping 0x2B0A:001 (P318.01), 0x2B0A:002 (P318.02).

Fault (configurable)

  • The event can only be reset after a blocking time.

Blocking time: 2 s

Setting parameters: 0x2D4B:003 (P308.03)
Fault ID: 9024
Hex: 0x2340
Description: Short circuit at the motor end
Keypad display: Motor shorted
Cause Remedy Severity/response

Short circuit of motor cable
