Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00384005 EVF8203-E is a 0.75 kW frequency inverter from the 8200 Vector product series designed for dynamic speed and torque regulation of AC induction motors. Operating on a supply voltage range of 180 V AC to 264 V AC across either single-phase or three-phase 230 V AC mains, this compact IP20 unit delivers a rated output current of 4 A with a peak overload capacity of 6 A for up to 60 seconds. Its core architecture separates the main power unit from interchangeable operating and communication options, featuring flexible control modes including linear V/f, quadratic V/f for pumps and fans, and sensorless vector control. The inverter also includes an integrated brake chopper circuit to handle regenerative kinetic energy from high-inertia mechanical loads.
When putting a replacement unit into service, proper configuration transfer is critical because parameter datasets must match the specific machine drive requirements. The EVF8203-E stores up to four independent parameter sets in non-volatile EEPROM memory, which can be configured using Global Drive Control (GDC) software version 4.0 or above, or transferred using the optional XT Keypad (E82ZBC001). Mechanical swap-out is streamlined by the modular hardware layout, allowing the existing plug-in function module—such as the E82ZAFS, E82ZAFCC, or E82ZAFPC—to be removed from the original drive and mounted directly onto the replacement power unit without re-wiring fieldbus networks. Specialist support from ABC Industrial Parts can assist maintenance personnel with parameter extraction, backup restoration, and drive commissioning for seamless machine integration.
Diagnostic information is available directly on the front panel via dual LED indicators, where a green LED signals operational readiness or running states and a red LED alerts to active TRIP error conditions. Technical personnel can evaluate recent trip history through parameter memory locations C0161 to C0164, inspect active fault codes via C0168, or observe drive status register C0183 either on the keypad display or within the GDC software diagnostic window. Common field issues such as output overcurrent, earth faults, line voltage dips, or motor overtemperature can be addressed through system wiring and parameter checks. However, severe internal conditions like EEPROM memory corruption or gate driver failure indicate hardware-level issues that are not field-serviceable, where rapid unit repair or a pre-tested exchange module from ABC Industrial Parts provides the fastest path to restoring production line operation.

Programming and Configuration
Parameter management and drive commissioning for the Lenze EVF8203-E 00384005 frequency inverter are performed using either the plug-in XT Keypad (E82ZBC001) or Lenze Global Drive Control (GDC) PC software version 4.0 or higher. The inverter contains internal non-volatile EEPROM memory capable of holding up to four complete parameter sets. This multi-dataset capability enables machines to easily switch between distinct operational profiles or recipes without reloading drive software.
When uploading, editing, or backing up drive parameters, GDC software connects through a PC System Bus adapter or serial interface attached to the drive's function module interface. Standard settings such as acceleration time (C0012), deceleration time (C0013), and motor control modes can be modified and saved. In instances where parameter corruption occurs or a clean setup is required, loading factory defaults can be triggered via parameter C0002.
Communication and System Integration
The EVF8203-E 8200 Vector inverter utilizes a modular hardware design that separates power control from fieldbus communication. System integration relies on interchangeable plug-in function modules that attach directly to the front interface slot of the inverter. Supported communication options include fieldbus protocols such as CANopen, PROFIBUS-DP, and LECOM RS-232/485 interfaces utilizing modules like the E82ZAFS, E82ZAFCC, and E82ZAFPC.
Networking via the internal system bus (CAN) enables high-speed process data transmission and remote monitoring across automation networks. Interruption monitoring is configurable using watchdog timeout settings such as parameter C0357, ensuring system safety and enabling automated shutdown actions in the event of master communication loss.
Diagnostics and Status Indication
The Lenze EVF8203-E features two status LEDs on the front panel that provide immediate visual feedback regarding drive operation. The green LED indicates drive readiness when flashing (drive inhibit) and continuous operation when solid green. A solid red LED signals an active TRIP fault condition, indicating that normal drive output is suspended due to an internal or external fault.
Comprehensive diagnostic oversight is accessible via keypad parameters or PC-based software tools. Keypad parameter register C0183 displays the current operational state, while register C0168 displays the active fault code. Historical trip data is maintained in parameters C0161 through C0164, which record the last four fault events for post-failure analysis.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid | TRIP error active / drive fault status |
| Green LED | Green - Solid / Flashing | Drive operational / ready state (Blinking = Drive ready/inhibit, Solid = Drive enabled/running) |
Replacement and Spare Part Considerations
When replacing a legacy Lenze 00384005 EVF8203-E drive, ensuring complete parameter and hardware alignment is critical. Because the 8200 Vector series separates power hardware from the control interface, technicians can swap the existing function module (such as PROFIBUS or CANopen modules) to the spare power chassis. Parameter configuration must be saved from the original inverter or written from a known software backup onto the new unit before restarting machinery.
Verify that the supply voltage matches the 1x 230 V AC or 3x 230 V AC requirement and that the output cabling to the motor terminals U, V, and W is secure. For long-term facility modernization where legacy 8200 Vector units are being phased out, Lenze offers the i510 and i550 Cabinet frequency inverter series as modern functional replacement alternatives.
