Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00384004 EVF8202-E is a compact, control-cabinet-mounted frequency inverter within the Lenze 8200 vector series. Built for speed and torque regulation of three-phase AC induction motors, this 0.75 kW drive operates on a 230 V AC nominal supply voltage across a permissive range of 180 V to 264 V AC. It delivers a continuous output current of 4 A with an 8 kHz switching frequency and an adjustable output frequency range from 0 Hz to 480 Hz. Control methods include linear or quadratic V/f characteristics for standard centrifugal pump and fan applications, as well as sensorless vector control for demanding high-torque machinery.
Connecting and commissioning a replacement EVF8202-E drive requires attention to network interfaces and parameter configurations. The device features an integrated Automation Interface (AIF) slot designed for modular fieldbus cards, including CANopen (E82ZAFC), PROFIBUS-DP (E82ZAFDP), and LECOM RS-232/RS-485 interfaces. A spare drive requires transferring parameter files stored in the non-volatile internal EEPROM, which holds up to four switchable parameter sets. Parameter transfer and drive configuration are managed via Lenze Global Drive Control (GDC) software or the portable XT Keypad (E82ZBC). Reinstalling the original AIF module and reloading saved drive profiles ensures complete operational compatibility. Technical specialists at ABC Industrial Parts can assist with parameter extraction from donor hardware or preparing a replacement unit for immediate service.
Real-time operational feedback is provided through dual LED indicators on the front faceplate and accessible diagnostic parameters. A solid green LED signals that the inverter is enabled and running, whereas a blinking green LED indicates an active controller inhibit or mains connection without drive enablement. A solid red LED points to an active TRIP condition that disables power output, while a blinking red LED warns of an active threshold alert. Fault history is stored in parameter C0168, with active operational status available in parameters C0183 and C0161. Initial checks should confirm line supply voltage, cable connections, and heatsink thermal conditions. Persistent errors, such as hardware faults H05, power stage failures H10, or unresolvable OC1 short circuits, indicate non-serviceable internal component failure. In these instances, procuring a tested replacement or utilizing repair services through ABC Industrial Parts provides a rapid path back to production.

Programming and Configuration
Engineering and parameter adjustment for the Lenze EVF8202-E frequency inverter are conducted using Lenze Global Drive Control (GDC) software connected via a serial interface, or locally using the plug-in XT Keypad (E82ZBC). Drive settings are retained inside internal non-volatile EEPROM memory, which holds up to four independent, switchable parameter sets. These parameter sets permit rapid changeover of operating parameters for different products without requiring continuous downloading from a master controller.
When commissioning a replacement unit, parameter data must be reloaded from a saved GDC project file or cloned from an existing drive using the XT Keypad. Essential settings include motor nameplate parameters, selection of V/f curve or sensorless vector control mode, acceleration and deceleration ramp times (parameters C0012 and C0013), and fieldbus network parameters. Proper alignment of these configurations ensures correct motor acceleration performance and activates protective functions such as I2t motor thermal monitoring.
Communication and System Integration
The Lenze EVF8202-E drive integrates into automated control environments via a plug-in Automation Interface (AIF) slot. This interface accepts expansion modules designed for various fieldbus and serial standards, enabling real-time control and remote monitoring from central programmable logic controllers.
Compatible plug-in options include the E82ZAFC System Bus module for CANopen networks, the E82ZAFDP module for PROFIBUS-DP, and LECOM RS-232 or RS-485 serial communication interfaces. When replacing an existing drive, removing the functional AIF card from the original unit and seating it into the replacement inverter preserves hardware physical interfaces, though bus node addressing and parameters must be verified upon installation.
Diagnostics and Status Indication
Visual status diagnostics on the EVF8202-E are provided by two faceplate LEDs indicating operational readiness and trip conditions. Parameter readouts C0183 and C0161 display real-time operating states and control status directly via connected software or keypad displays.
The inverter logs recent diagnostic events in parameter C0168, which serves as a fault history buffer. Detailed status menus, actual operating values, and historical trip logs can be navigated using the text interface on the XT Keypad (E82ZBC) or through the diagnostic monitor within Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready / Operation) | Green - Solid / Blinking | ON: Inverter enabled and ready for operation; BLINKING: Controller inhibit active (IMP block) or mains supply connected without drive enable. |
| Red LED (Trip / Fault) | Red - Solid / Blinking | ON: Fault/TRIP active, drive output disabled; BLINKING: Warning condition active. |
Replacement and Spare Part Considerations
Replacing a failed unit with a spare Lenze 00384004 (EVF8202-E) requires verifying electrical and physical specifications. The replacement inverter must match the 0.75 kW power rating and 230 V AC operating voltage to fit within existing cabinet space and wire directly to existing supply circuits.
Because frequency inverters store machine-specific settings in internal memory, a spare drive must be parameterized prior to operation. Transferring saved parameter sets via Global Drive Control (GDC) software or cloning them with an XT Keypad ensures ramp times, I/O terminal functions, and fieldbus parameters match original operational conditions. The plug-in AIF module must also be transferred from the existing unit to maintain network integration.
Although the Lenze 8200 vector series is phased out—with the Lenze i550 cabinet frequency inverter identified as its official modern successor line—sourcing an exact replacement EVF8202-E eliminates the need for cabinet rewiring or control software modification.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
