i550 cabinet frequency inverter

The i550 cabinet frequency inverter is a compact control cabinet device with scalable functionality. It is versatile, reliable, and easy to use.
The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met.
Application areas: Conveyor drives, traveling drives, winding drives, hoist drives, extruders, packaging machines, pumps, fans, ...

Highlights

  • Space saving design: 60 mm wide (up to 4 kW), 130 mm deep (up to 11 kW), with zero-clearance mounting
  • Innovative interaction (e.g. over WLAN) makes new record-breaking commissioning times and convenient diagnostics a reality
  • Optionally available with "Safe Torque Off (STO)" with SIL 3 (EN IEC 61508) and Performance Level e (EN ISO 13849-1)
  • For the greatest possible flexibility available as a complete device or in individual parts (Power Unit, Control Unit and Safety Unit)

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

Check motor cable for short circuit.

Fault

  • The inverter is disabled immediately. The motor has no torque (is coasting).
  • The event can only be reset after a blocking time.

Blocking time: 2 s
Fault ID: 8992
Hex: 0x2320
Description: Short circuit or earth leakage at the motor end
Keypad display: Earth leak
Cause Remedy Severity/response
  • Short circuit/earth fault of motor cable
  • Capacitive charging current of the motor cable too high.
  • Check motor cable.
  • Check length of the motor cable.
  • Use shorter or lower-capacitance motor cable.

Fault

  • The inverter is disabled immediately. The motor has no torque (is coasting).
  • The event can only be reset after a blocking time.

Blocking time: 2 s
Fault ID: 8784
Hex: 0x2250
Description: CiA: Continuous over current (internal)
Keypad display: PU over current
Cause Remedy Severity/response
  • Continuous overcurrent on the inverter/ motor side.
  • Overcurrent at the brake chopper (brake transistor).
  • DC bus relay has not been closed due to a malfunction.
  • Check motor and wiring for short circuits.
  • Check brake resistor and wiring.
  • Check motor switching.
  • Check settings of the motor data.

Fault

  • The inverter is disabled immediately. The motor has no torque (is coasting).
  • The event can only be reset after a blocking time.

Blocking time: 2 s
