Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV552_2C is a panel-mounted frequency inverter from the 8200 Vector series, engineered to provide dynamic speed and torque control for 3-phase AC asynchronous motors. Operating from a 3-phase 230V AC input across a permissible voltage range of 180V to 264V AC, this AC drive provides a rated power output of 5.5 kW (7.5 HP) with a continuous output current of 24A. It supports linear V/f, quadratic V/f, sensorless vector control, and torque control modes, making it suitable for applications such as conveyor systems, industrial pumps, ventilation fans, material handling equipment, and machine tools.
Designed with a modular hardware configuration, the drive consists of a base power section and an interchangeable plug-in function slot. This setup accepts function and fieldbus communication modules including CANopen, PROFIBUS-DP, DeviceNet, INTERBUS, and Modbus RTU or LECOM. Commissioning and parameter cloning are managed using either the plug-in Lenze E82ZBC XT Keypad Module or Lenze Global Drive Control (GDC) PC software. The internal non-volatile EEPROM stores up to four independent parameter sets to facilitate rapid parameter duplication across identical units. When replacing an existing unit, ABC Industrial Parts can assist with parameter backup extraction and configuration support to streamline restoring system operation.
Comprehensive diagnostic capability is provided via dual-color red and green status LEDs located on the front panel and module faces, signaling operational readiness, pulse inhibit, and active fault states. Detailed troubleshooting is performed by reading parameters C0161 for active TRIP faults and C0168 for historical TRIP events using the keypad module or GDC software. Common maintenance checks include verifying mains phase balance, evaluating input line supply voltages, and testing output wiring integrity across phases U, V, and W. In cases where internal hardware failures or memory defects prevent normal drive start-up, ABC Industrial Parts provides tested replacement units and repair options to minimize machine downtime.

Programming and Configuration
The Lenze E82EV552_2C utilizes internal non-volatile EEPROM memory capable of retaining up to four independent parameter sets. This feature allows different operational profiles to be stored within a single drive or duplicated directly to replacement drives without losing configuration data during power outages.
Parameter setup and drive commissioning are conducted using either the plug-in Lenze E82ZBC XT Keypad Module or Lenze Global Drive Control (GDC) PC software. Critical parameters include acceleration ramp time (C0012), deceleration ramp time (C0013), and motor nameplate parameters (C0087, C0088, C0089). If a parameter loading conflict or data corruption occurs, resetting parameter C0002 to 1 restores the inverter to factory default values for fresh commissioning.
Communication and System Integration
System integration for the 8200 Vector series relies on a modular function slot designed to accept interchangeable fieldbus and function modules. Supported fieldbus options include CANopen, PROFIBUS-DP, DeviceNet, INTERBUS, and Modbus RTU or LECOM, allowing direct control integration with various PLC platforms.
In addition to serial and fieldbus interfaces, the inverter provides configurable digital outputs for remote signaling of fault conditions and operational readiness. The carrier switching frequency can be adjusted up to 16 kHz to satisfy low-noise motor operation requirements in sensitive ambient environments.
Diagnostics and Status Indication
Visual status indication is provided by dual-color red and green LEDs located on the front of the inverter and on installed function modules. Solid or flashing illuminated patterns signal drive operational readiness, active fault trips, or controller pulse inhibit conditions.
Detailed fault diagnostics are retrieved electronically by inspecting diagnostic parameters. Active fault conditions are displayed in parameter C0161 (current TRIP fault), while historical events are saved in parameter C0168 (TRIP history memory). These parameters are accessible via the E82ZBC XT Keypad Module or dedicated diagnostic windows within Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Front / Module LEDs | Red / Green - Solid / Flashing | Displays drive operational status, readiness, active error state, or pulse inhibit condition. |
Replacement and Spare Part Considerations
When swapping out a damaged Lenze E82EV552_2C, ensure the spare drive matches the original 3-phase 230V rating and 24A current output. Installed fieldbus and function modules must be unclipped from the donor frame and mounted into the replacement unit to maintain fieldbus address and physical I/O connectivity.
Parameter sets stored in the original inverter memory must be restored to the replacement unit using the Lenze E82ZBC XT Keypad Module or Global Drive Control (GDC) software. While the 8200 Vector series is an end-of-life legacy product, maintaining duplicate spares allows existing production machinery to remain operational. For future machine retrofits or complete platform upgrades, Lenze recommends migrating to the i550 cabinet frequency inverter series (recommended successor model i55AE255C0000000S).
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit | Short circuit in motor circuit or dynamic motor load peak during acceleration | Short circuit or ground fault in motor cable, motor winding fault, acceleration time too short | Check motor and motor cable for short circuits / ground faults, verify acceleration time setting (C0012). If fault persists with motor disconnected, internal inverter hardware failure requires unit repair or replacement. |
| OC2 | Earth Fault / Deceleration Overcurrent | Earth fault or overcurrent trip during deceleration phase | Earth fault in motor cable/winding, deceleration time setting too short | Inspect motor insulation resistance to ground, extend deceleration time (C0013). |

| OC5 | Overcurrent During Acceleration | Dynamic motor current threshold exceeded during speed ramp-up | Ramp generator time too short, motor parameter mismatch, excess inertia | Increase ramp-up time C0012, check motor nameplate parameter settings (C0087/C0088/C0089). |
| OU | DC Bus Overvoltage | DC bus voltage exceeds overvoltage shutdown threshold (> 400V DC) | Regenerative energy fed back from motor during deceleration, deceleration time too short, missing or defective braking resistor / braking module | Increase deceleration ramp time C0013, install external braking module/resistor if heavy regenerative load. |
| LU | DC Bus Undervoltage | DC bus voltage dropped below minimum operation threshold (< 215V DC) | Supply line voltage failure, phase loss, input voltage drop, loose supply terminal | Check AC line input supply voltage, check line fuses and wiring terminals. |

| OH7 | Motor Temperature Sensor Wire Break | Open circuit detected on thermistor/PTC evaluation input terminals T1/T2 | Broken signal wire, loose terminal connection, defective PTC sensor | Check sensor wire continuity and connections at terminals T1 and T2. |
| EE | EEPROM Memory Fault | Checksum error or read/write defect in internal non-volatile EEPROM memory | Power interruption during parameter write, internal EEPROM chip failure | Reload factory default settings (C0002 = 1). If fault cannot be cleared, internal board-level hardware failure requires unit replacement. |
