i550 motec

The i550 motec frequency inverter for wall mounting and motor mounting in protection class IP66 (UL Type 4X indoor) is the optimal decentralized drive solution. The inverter can be extended for universal use with an extension box with disconnect switch with/without Type E combination motor controller and operating elements.
Fast mounting and easy commissioning thanks to user-friendly tools as well as connections for commercially available connectors are the focus of this inverter. Parameters, drive behavior and usability correspond to our proven frequency inverters. Rounded off by high energy efficiency, we thus offer a modern and sustainable drive solution.
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

  • Compact solution for decentralized drive technology, wall-mounted or motor-mounted, with high protection class IP66 (UL Type 4X indoor)
  • Wall-mounted expandable: Extension box with disconnect switch with/without Type E combination motor controller and operating elements
  • Fast mounting due to pluggable, standardized connections (plug & play)
  • Four IO-Link ports with limited IO-Link master functionality for easy data exchange between IO-Link sensors and actuators
  • Integrated regenerative module for very high energy efficiency - a brake resistor is no longer required
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
