Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00384006 EVF8204-E is a 3.0 kW (4.0 HP) panel-mount AC frequency inverter belonging to the Lenze 8200 vector product family. Designed for 3-phase AC power systems operating between 320V and 528V AC (400V or 480V nominal) at 45 to 65 Hz, this drive provides precise motor speed and torque regulation for 3-phase asynchronous motors using sensorless vector control or traditional V/f characteristics. The compact IP20 enclosure incorporates an integrated heatsink for direct cabinet mounting, supporting continuous output currents of 7.3 A at 400V and 6.1 A at 480V.
Putting a spare EVF8204-E unit into service requires matching the installed modular interface hardware and transferring operational parameters. The drive power unit relies on interchangeable plug-in function modules inserted into slot 1, such as the standard E82ZAFSC or application E82ZAFAC I/O modules, as well as optional fieldbus cards for network integration. Because a replacement unit contains factory settings, parameter sets must be cloned from the existing drive or restored from a saved configuration using the XT Keypad EMZ2101ED or Global Drive Control (GDC) PC software. The inverter supports dual non-volatile internal parameter memories, allowing efficient transfer of operational profiles without full manual re-commissioning. Technical support from ABC Industrial Parts can assist maintenance teams with parameter cloning and verifying module compatibility prior to power-up.
Diagnostic information is displayed directly through two front status LEDs and accessible via internal software parameters. A solid green LED indicates the controller is ready with pulses enabled, while a blinking green LED signals pulse inhibit; a solid red LED indicates a TRIP fault condition, whereas a blinking red LED denotes an active warning. Detailed fault diagnostics can be evaluated by inspecting parameter C0161 for active trip codes or parameter C0168 to analyze the internal fault history buffer. While external issues like supply dips, line phase loss, or heatsink clogging can be addressed on-site, fault codes indicating internal EEPROM corruption (EEr) or power section failure (H05) point to non-field-serviceable hardware faults. In such cases, sourcing a tested replacement drive or sending the failed unit for repair via ABC Industrial Parts offers a dependable path back to full production.

Programming and Configuration
The Lenze EVF8204-E frequency inverter utilizes a flexible configuration architecture structured around non-volatile internal parameter memory. The drive features dual stored parameter sets, enabling operators to maintain primary and secondary machine settings directly on the device. Parameters control motor characteristics, acceleration and deceleration ramps (C0012 and C0013), maximum speed settings (C0015), and interface behavior.
Field programming and parameter transfers are carried out using the plug-in XT Keypad EMZ2101ED or PC-based Global Drive Control (GDC) software. The XT Keypad connects directly to the drive front to grant access to parameter menus, monitor operating conditions, and copy parameter profiles between drives. Alternatively, GDC software provides real-time diagnostic monitoring and online/offline parameter management over a LECOM PC connection.
When commissioning a replacement inverter, full parameter cloning ensures the new unit replicates the exact control loops, speed limits, and I/O allocations of the original drive. Parameter C0002 allows technicians to reload factory default configurations if a parameter reset is required prior to transferring saved user profiles.
Communication and System Integration
System integration for the EVF8204-E is achieved through a modular slot arrangement on the drive housing. Slot 1 accepts plug-in Function Modules that determine the hardwired I/O capabilities and serial communication channels. Standard options include the E82ZAFSC Standard I/O module and the E82ZAFAC Application I/O module, which configure discrete control inputs, analog reference signals, and status outputs.
For higher-level network connectivity, the drive accommodates optional Communication Modules across common industrial fieldbus networks. Options include the PROFIBUS-DP module (EMF2133IB) and CANopen modules (EMF2173IB / EMF2178IB), as well as INTERBUS and serial LECOM interfaces. These modules allow higher-level PLCs to command speed setpoints, monitor drive operational status, and read out active diagnostics.
The drive delivers smooth low-end torque control and supports configurable switching frequencies up to 16 kHz for low-noise motor operation. An output frequency range spanning 0 to 480 Hz makes the EVF8204-E versatile across dynamic material handling, conveyor drives, continuous fans, and pump systems.
Diagnostics and Status Indication
Real-time visual status monitoring is provided by green and red LEDs situated on the drive faceplate. The green LED signals basic operational state, remaining solid when the inverter is running with pulses enabled and flashing when pulse inhibit is engaged. The red LED provides immediate indication of system warnings and faults, flashing during active warning states and illuminating solid upon a TRIP fault.
For comprehensive fault analysis, engineers can query parameter C0161 using an XT Keypad or GDC software to retrieve the active error code. Furthermore, parameter C0168 stores an internal fault history buffer, allowing maintenance personnel to review historical trip conditions and trace intermittent machine shutdowns.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation / Ready) | Green - Solid / Blinking | Solid = Controller ready / pulse enabled (running). Blinking = Pulse inhibit active / drive inhibited. |
| Red LED (Trip / Error) | Red - Solid / Blinking | Solid = Active TRIP fault condition. Blinking = Active warning / message. |
Replacement and Spare Part Considerations
Replacing a Lenze EVF8204-E drive involves more than physically unmounting the power chassis. Because the base drive unit does not include fixed I/O terminals or fieldbus connectors, the existing Function Module (such as E82ZAFSC or E82ZAFAC) or fieldbus module (such as EMF2133IB) must be carefully unseated from slot 1 of the old drive and reinstalled into the replacement unit.
Parameter transfer is mandatory before running the machine. Installing an unconfigured spare will result in default factory control behavior, which may cause unexpected motor operation or fieldbus communications failure. Parameters can be copied directly using the XT Keypad EMZ2101ED or transferred from a saved project file using Global Drive Control (GDC) software.
For long-term strategy planning, the Lenze i550 cabinet series is the recommended modern successor family. However, utilizing an original EVF8204-E replacement drive avoids the physical cabinet modifications, wiring re-routing, and PLC software updates required when modernizing to a newer drive platform.

Frequently Asked Questions
What software and keypad are used to program the Lenze EVF8204-E?
The EVF8204-E is configured using Global Drive Control (GDC) PC software or the optional plug-in XT Keypad EMZ2101ED.
Can I swap an EVF8204-E drive directly without programming?
No, a replacement drive contains factory default settings. You must transfer the parameter configuration from the original drive or backup file using the XT Keypad or GDC software, and install the appropriate plug-in function module in slot 1.
What do the front LEDs on the EVF8204-E indicate?
The green LED indicates operating state (solid for ready/running, blinking for pulse inhibit). The red LED indicates errors (solid for a TRIP fault, blinking for a warning).
How do I read out active fault codes on this drive?
Active fault codes can be read via parameter C0161 using the XT Keypad EMZ2101ED or GDC PC software. Historical faults are stored in parameter C0168.
Which communication modules are supported by the EVF8204-E?
The drive supports plug-in communication modules in slot 1, including PROFIBUS-DP (EMF2133IB), CANopen (EMF2173IB / EMF2178IB), INTERBUS, and LECOM.
What action should be taken if fault code H05 or EEr appears?
Code EEr represents an EEPROM memory checksum error, which may be cleared by resetting parameters to factory defaults via C0002=1. Code H05 indicates an internal hardware/power section failure that is not field-serviceable and requires drive replacement or unit repair.
