Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV552_4C is a 5.5 kW (7.5 HP) frequency inverter from the Lenze 8200 Vector series, engineered for speed and torque regulation of standard three-phase AC induction motors. Operating on a three-phase supply voltage ranging from 320 V AC to 528 V AC at 45 to 65 Hz, this unit delivers a continuous output current of 13 A and operates across an output frequency range of 0 to 480 Hz. The drive supports multiple operating modes including sensorless vector control, open-loop torque control, and configurable linear or quadratic V/f characteristic curves. In ordering codes and part numbers, the wildcard character denotes the cooling mounting style: 'K' designates a standard heatsink unit (E82EV552K4C), 'C' indicates a Cold Plate design (E82EV552C4C), and 'P' represents a push-through mounting variant.
Designed with a modular architecture, the inverter incorporates a plug-in Function Module (FIF) slot that accommodates interchangeable control and fieldbus cards, such as the E82ZAFPC PROFIBUS-DP module or the E82ZAFCC System Bus (CANopen) module. This design allows control modules to be installed or swapped while keeping main field wiring intact. Commissioning a replacement unit requires configuring parameters and installing the matching interface module. The inverter stores up to four independent, switchable parameter profiles in internal EEPROM memory for multi-recipe application demands. Parameters can be backed up or transferred using the optional E82ZBC Keypad XT diagnostic module or Lenze Global Drive Control (GDC) software, with expert parameter extraction from donor drives supported by ABC Industrial Parts when original files are unavailable.
System state and troubleshooting information are provided via front-panel LED indicators and diagnostic parameters. A solid green LED signals active inverter operation, whereas a blinking green LED indicates an initialized drive or ready state without enable. A blinking or solid red LED alerts operators to an active fault or TRIP condition. Real-time operating parameters in the C005x range display DC bus voltage, output current, actual frequency, and heatsink temperature, while code C0168 stores the last four recorded TRIP events. Basic troubleshooting includes inspecting supply voltage, line chokes, motor wiring, and fieldbus connections. When internal microcode, memory, or power stage errors occur, field-level repairs are not recommended, and opting for a tested exchange unit or specialized repair through ABC Industrial Parts provides the fastest resolution.

Programming and Configuration
Parameterization and commissioning of the Lenze E82EV552_4C frequency inverter are conducted using Lenze Global Drive Control (GDC) software or the plug-in E82ZBC Keypad XT diagnostic panel. Drive response is managed by structured code settings, including acceleration ramp time (C0012), deceleration ramp time (C0013), and rated motor current (C0087).
The internal non-volatile EEPROM memory supports four complete, switchable parameter sets. This functionality allows distinct operating profiles or recipe settings to be toggled dynamically without reloading software parameters from an external controller. Restoring factory defaults across parameters is performed by executing reset code C0002.
Communication and System Integration
The E82EV552_4C utilizes an integrated Function Module (FIF) interface slot that accepts plug-in communication modules. Supported options include the E82ZAFPC PROFIBUS-DP card and E82ZAFCC System Bus (CANopen) module, alongside cards for DeviceNet and LECOM interfaces.
Because field communication and I/O options are housed within the removable FIF module, the base drive can be exchanged without rewiring signal or fieldbus connections. Network timeout monitoring actively tracks cyclically transmitted process data; a loss of fieldbus master communication triggers a CE1 process data error.
Diagnostics and Status Indication
Diagnostic indication on the drive comprises front-panel status LEDs and accessible monitoring codes. Live operating data—such as output current, actual frequency, DC link voltage, and heatsink temperature—can be read via the C005x parameter group. Historical fault tracking is stored in parameter C0168, which retains a log of the last four TRIP occurrences.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Off / Blinking / Solid | Off: Normal operating condition. Blinking/Solid: Fault present or TRIP condition active. |
| Green LED | Green - Blinking / Solid | Blinking: Drive initializing or ready state without enable. Solid: Drive operating / inverter enabled. |
Replacement and Spare Part Considerations
When replacing a Lenze E82EV552_4C inverter, verify the mounting suffix designated by the wildcard character in the full part number. A unit marked 'K' (E82EV552K4C) uses a standard heatsink, 'C' (E82EV552C4C) designates a Cold Plate surface, and 'P' corresponds to a push-through cabinet installation. The replacement unit must match the mechanical cooling method to fit the existing cabinet enclosure.
Ensure the original Function Module (FIF) is transferred to the replacement unit or that an identical card is installed. Parameter files stored in the internal EEPROM must be transferred to the replacement unit using the E82ZBC Keypad XT display panel or Lenze Global Drive Control (GDC) software to maintain system operation.
For long-term migration strategy, the Lenze i550 cabinet frequency inverter serves as the recommended successor line for legacy 8200 Vector drives.
