Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV302_4C200 is a 3.0 kW frequency inverter from the 8200 Vector series, designed for variable speed control of standard three-phase AC induction motors. Operating from a 3-phase supply of 400 V AC to 480 V AC across a permissible voltage range of 320 V AC to 528 V AC, this inverter generates an adjustable output voltage up to mains level with an output frequency range of 0 Hz to 480 Hz. It delivers a rated current of 7.3 A at 400 V and 6.1 A at 480 V AC with a default switching frequency of 8 kHz. Built as a variant without an integrated EMC filter, this unit is intended for installation in control cabinets equipped with central or external filter arrangements.
System connectivity and control integration are managed via a front-mounted function module slot that accepts standard I/O (E82ZAFSC), application I/O (E82ZAFAC), or fieldbus interfaces such as CANopen (E82ZAFCC) and PROFIBUS-DP (E82ZAFPC). Putting a spare drive into operation requires transferring motor parameters and application settings stored in the internal EEPROM. Fast drive swapping is supported through the optional plug-in memory module (E82ZMS001), allowing direct parameter transfer without connecting a PC. Inverters can also be configured using an E82ZBC keypad or Lenze Global Drive Control (GDC) software, with technical support available from ABC Industrial Parts for parameter extractions and configuration backups.
Diagnostic evaluation is handled through onboard red and green status LEDs, as well as status displays on the optional E82ZBC keypad. Technicians can analyze active trips using the status word monitor (C0150) or review saved events in the GDC software fault history log (C0168). Common drive trips include overcurrent conditions (OC1, OC2, OC3), DC bus overvoltage (OU), and communication timeouts (CE0, CE1). Initial field checks should cover mains input stability, motor cable insulation, thermal PTC sensor wiring across terminals T1 and T2, and module seating. Internal electronic failures (H05) or persistent parameter errors (Pr) are not field-serviceable, making a tested replacement drive from ABC Industrial Parts the most reliable path to minimizing machine downtime.

Programming and Configuration
The Lenze E82EV302_4C200 utilizes non-volatile internal EEPROM memory capable of retaining two complete parameter sets. Drive commissioning and parameter adjustments can be performed using the optional E82ZBC plug-in keypad module or via a PC using Lenze Global Drive Control (GDC) software. Control parameters govern motor control modes, ramp times, thermal limits, digital input assignments, and fieldbus communication settings.
For maintenance operations, the drive supports the Lenze E82ZMS001 plug-in memory module. This module allows direct hardware cloning of saved parameter sets from one inverter to another without needing a laptop or software interface. When replacing a failed unit, swapping the memory module into the replacement drive automatically restores all machine-specific operational parameters.
Parameter management includes dedicated codes such as C0002 for restoring factory defaults, C0012 and C0013 for adjusting acceleration and deceleration times, C0018 for switching frequency adjustments, and C0075 for motor thermal model settings.
Communication and System Integration
System integration for the E82EV302_4C200 is built around a modular architecture featuring an integrated front slot for function, I/O, and fieldbus modules. Depending on application requirements, users can attach standard I/O modules (E82ZAFSC) or application I/O modules (E82ZAFAC) for local terminal control.
For network and fieldbus environments, the drive accepts various communication modules including CANopen (E82ZAFCC), PROFIBUS-DP (E82ZAFPC), DeviceNet, and INTERBUS. These modules enable real-time control, status monitoring, and parameter adjustment directly from higher-level PLCs or plant control networks.
The drive also includes dedicated onboard terminals T1 and T2 for direct connection of PTC thermistor sensors embedded in the motor windings, enabling integrated motor thermal monitoring independently of fieldbus communication.
Diagnostics and Status Indication
Visual status monitoring is provided on the front panel via dual red and green LEDs. These LEDs indicate operational readiness, active drive enable status, warning conditions, and active fault trips.
Detailed trip diagnosis and operational status monitoring can be accessed through the E82ZBC keypad display or via Global Drive Control (GDC) software. Key diagnostic parameters include parameter C0150 for real-time status word monitoring and code C0168, which maintains a history log of recent fault codes.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Status LEDs | Red / Green - Solid / Flashing | Displays inverter operating status and active fault conditions |
Replacement and Spare Part Considerations
When selecting a replacement drive for the Lenze E82EV302_4C200, pay attention to the exact model suffix. The designation '200' indicates that this model does not feature an integrated EMC filter. Installing a replacement variant with an integrated filter in an environment designed for external filtering may cause compatibility issues or improper line grounding setups.
To complete a rapid drive exchange, transfer the plug-in memory module (E82ZMS001) or plug-in fieldbus module (such as E82ZAFCC or E82ZAFPC) from the original unit to the replacement inverter. Ensure the fieldbus module is firmly seated in slot 1 before restoring system power.
If the memory module is damaged or unreadable, parameters must be reloaded from a software backup via Lenze Global Drive Control (GDC) or re-entered manually using the E82ZBC keypad module. Following parameter loading, execute an operational check of motor rotation, thermal protection settings (C0075), and network communications.
