Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8244-E is a 8200 vector series panel-mounted frequency inverter engineered for precise velocity and torque control of 3-phase AC induction motors. Rated for an output power of 3.0 kW (4.0 HP), this variable frequency drive operates on line input voltages from 320 V AC to 528 V AC. It provides continuous rated output currents of 7.3 A at 400 V AC and 6.1 A at 480 V AC. Built with a modular housing, the drive separates its primary power section from a dedicated control slot that accepts various pluggable function modules.
Integrating a replacement EVF8244-E drive into an existing control cabinet requires proper configuration alignment and hardware transfer. The module slot supports function modules such as CANopen (EMF2175IB), PROFIBUS-DP (EMF2133IB), and LECOM RS232/RS485 adapters. Internal EEPROM memory holds up to four switchable parameter sets. Parameter transfer between units is accomplished using parameter code C0003 on an EMZ2101 keypad or through Lenze Global Drive Control (GDC) PC software. A replacement unit will not operate correctly until motor and application settings are loaded onto the drive. ABC Industrial Parts offers tested replacement drives and support for parameter transfer procedures.
System health and operational states are reported via front LED indicators and keypad readout codes C0161 to C0164. In the event of operational interruptions, first-line checks should confirm input AC supply voltage, enable signal status on terminal 28, fieldbus module seating, and motor cable insulation. Internal memory or control board failures, such as a persistent EEPROM error (code EE), are not field-serviceable. In these instances, installing a pre-tested replacement drive from ABC Industrial Parts offers a dependable path to restore machine operation.

Programming and Configuration
The EVF8244-E is programmed using Lenze Global Drive Control (GDC) PC software or through optional keypads including the EMZ2101 and XT EMZ2201BS. Non-volatile internal EEPROM memory stores up to four complete, switchable parameter sets, permitting multi-recipe configurations and simplified parameter management.
When commissioning a spare unit, existing parameters can be duplicated using parameter code C0003 on an EMZ2101 keypad or uploaded and downloaded using GDC software with an EMF2171IB system bus adapter. Restoring the exact parameter profile ensures proper motor protection limits, speed ramps, and terminal control functions.
Communication and System Integration
System integration for the Lenze 8200 vector series relies on pluggable function modules inserted directly into the drive's front control slot. This modular design permits connection to fieldbus networks without altering the underlying power section.
Supported communication modules include the EMF2175IB CANopen module, EMF2133IB PROFIBUS-DP module, and LECOM serial communication adapters (RS232/RS485). The drive provides frequency control from 0 Hz up to 480 Hz with a default switching frequency of 8 kHz.
Diagnostics and Status Indication
The EVF8244-E provides real-time status indication via two front-mounted LEDs and internal diagnostic registers. The green LED signals operational readiness or enabled status, while the red LED indicates active drive faults or trip conditions. Detailed fault histories are stored in parameter codes C0161 to C0164 and can be inspected via keypad or the GDC diagnostic monitor.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Fault / Error | Red - Solid / Flashing | Drive fault or error condition active |
| Operation / Ready | Green - Solid / Flashing | Drive enabled and operational or ready for operation |
Replacement and Spare Part Considerations
The Lenze 8200 vector series is discontinued and superseded by newer inverter platforms like the i550 cabinet series. However, the EVF8244-E remains directly usable as a spare part to keep existing production lines running without mechanical or electrical panel modifications.
When replacing a failed drive, technicians must verify that the replacement drive shares the exact power rating (3.0 kW / 4.0 HP) and that all pluggable function modules (such as CANopen or PROFIBUS cards) are moved from the original unit to the new drive. Parameters stored in memory must be restored to guarantee proper motor startup and control terminal behavior.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| IMP | Pulse Inhibit | Drive pulses are inhibited; power output stage is disabled. | Controller enable signal (terminal 28) missing or digital input condition active. | Apply high signal to terminal 28 (Controller Enable). |
| OC1 | Short Circuit / Overcurrent during Acceleration | Output current exceeds current threshold during acceleration phase. | Acceleration time set too short; motor cable short circuit; motor short circuit; excessive load inertia. | Increase acceleration time (C0012); check motor wiring and insulation; check motor sizing. |
| OC2 | Overcurrent during Deceleration | Output current exceeds threshold during deceleration phase. | Deceleration time set too short; braking energy too high. | Increase deceleration time (C0013) or connect braking module/resistor. |
| OC5 | Overcurrent at Constant Operation / Overload | Drive overloaded continuously at constant speed. | Mechanical blockage or continuous overload on motor. | Check mechanical load and motor torque requirement. |
| OU | DC Bus Overvoltage | DC bus voltage exceeded upper threshold limit. | Regenerative energy from motor during braking; deceleration ramp too fast; excessive mains voltage. | Extend deceleration time (C0013); install brake chopper / resistor; check input supply voltage. |
| LU | DC Bus Undervoltage | DC bus voltage fell below lower threshold limit. | Mains supply power outage, brownout, or loose supply wiring. | Verify input AC supply voltage and power wiring connection. |
| OH | Heatsink Overtemperature | Drive heatsink temperature exceeded maximum threshold. | Insufficient cooling airflow; fan failure; ambient temperature too high; clogged cooling fins. | Clean heatsink cooling fins; check control cabinet ventilation and internal fan operation. |
| OH4 | Motor Overtemperature | Motor thermistor / thermal contact triggered trip. | Motor thermal overload; insufficient motor cooling; defective PTC sensor wiring. | Allow motor to cool down; verify motor thermal protection settings and sensor wiring. |
| Earth | Earth Fault / Ground Fault | Current flow detected to earth ground at output terminals. | Ground fault in motor cable or motor winding. | Check motor cable and motor windings for isolation/ground resistance. |
| EE | EEPROM Memory Fault | Internal parameter memory checksum or read/write error. | Internal control board hardware failure or corrupted parameters. | Reset parameters to factory defaults (C0002); if fault persists, non-serviceable internal failure — replace unit. |
| NMAX | Maximum Speed Exceeded | Actual motor speed exceeded maximum configured threshold. | Incorrect motor parameter setting or overspeed driven by external load. | Check speed controller settings and speed limit parameter C0011. |
| CE0 | Communication Fault | Communication failure on system bus or optional fieldbus module. | Disconnected fieldbus cable; incorrect baud rate or station address setting. | Check fieldbus cabling, module seat, and bus configuration parameters. |
