Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00400041 (model EVF8221-E) is a 0.75 kW (1.0 HP) frequency inverter belonging to the Lenze 8200 Vector series. Designed for panel mounting inside industrial control cabinets, this AC drive operates on a 3-phase supply voltage ranging from 320 V AC to 528 V AC at 45 to 65 Hz. It delivers a continuous output current of 2.4 A at 400 V AC, with a 150% overload capacity of 3.6 A for up to 60 seconds to accommodate dynamic load demands. Supporting Sensorless Vector Control (SLVC), V/f characteristic control, and direct torque control across an output frequency range of 0 to 480 Hz, the unit incorporates an integrated brake chopper transistor for dynamic braking applications.
Connecting and configuring the EVF8221-E within an automation system relies on its modular physical interface, comprising dedicated Function Interface (FIF) and Automation Interface (AIF) expansion slots. The drive accommodates option modules such as the EMF2133IB PROFIBUS module, alongside CANopen, DeviceNet, INTERBUS, and LECOM RS-232/485 communication adapters. Commissioning a replacement unit requires transferring operational parameter sets, as a spare drive will not run existing machinery out of the box. Parameter configurations can be saved in the internal non-volatile EEPROM, which holds up to four switchable parameter sets, and transferred directly using the pluggable E82ZBC Keypad XT interface or via Lenze Global Drive Control (GDC) PC software. Maintenance teams replacing a failed unit can rely on ABC Industrial Parts for tested replacement drives and support with parameter transfer processes.
Real-time operational status and diagnostic indications on the EVF8221-E are visible through two front-panel LEDs and fieldbus register monitoring. A green LED indicates power and run status—remaining off when supply voltage is absent, blinking during controller inhibit or drive ready states, and glowing solid green when the drive is enabled and running. A red LED illuminates or blinks when a trip or warning condition occurs, such as short circuits (OC1), overvoltage (OU), undervoltage (LU), or heatsink overtemperature (OH). Detailed diagnostic records can also be read from the internal TRIP memory log using Keypad XT or GDC software. First-line troubleshooting should verify incoming phase voltage, motor insulation, cable connections, and fieldbus module seating. When internal hardware faults occur—such as internal power section failures (H05) or persistent EEPROM memory faults (EE)—board-level repairs or a fully tested replacement unit through ABC Industrial Parts provide the quickest route back to full operation.

Programming and Configuration
The Lenze EVF8221-E drive is configured using Lenze Global Drive Control (GDC) PC software or an optional plug-in E82ZBC Keypad XT operator panel. Operational settings are managed across four internal, switchable parameter sets stored in non-volatile EEPROM memory. This internal storage structure preserves machine configurations, acceleration and deceleration ramps, motor settings, and control modes during power outages without requiring battery buffering.
During initial commissioning or replacement workflows, parameter data can be transferred over a PC serial connection using GDC software or copied directly into the portable Keypad XT. The keypad allows parameter sets to be extracted from an operating or donor inverter and downloaded into a replacement unit on the factory floor, minimizing downtime and eliminating manual parameter entry.
Communication and System Integration
The physical architecture of the EVF8221-E includes two specialized option slots: a Function Interface (FIF) slot designed for I/O option modules and an Automation Interface (AIF) slot dedicated to fieldbus network modules. This modular slot design enables direct integration into automated control architectures without requiring external signal converters.
Supported communication adapters for the AIF slot include PROFIBUS-DP (such as module EMF2133IB), CANopen, DeviceNet, INTERBUS, and LECOM RS-232/485. Once an AIF module is installed, the frequency inverter communicates operating commands, speed setpoints, and internal diagnostic registers directly to higher-level PLCs and supervisory systems.
Diagnostics and Status Indication
Local diagnostic feedback on the EVF8221-E is provided by two LEDs on the front panel. The green LED indicates mains supply presence, drive readiness, and controller enable states. The red LED indicates active warnings and fault trips (TRIP/IMP). Detailed diagnostic monitoring—including active fault codes, historical TRIP memory log readouts, and fieldbus communication register values—is performed using the Keypad XT or Global Drive Control software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation / Ready) | Green - Off / Blinking / On | Off: No supply voltage. Blinking: Drive ready / controller inhibit active. On: Drive running / enabled. |
| Red LED (Fault / Trip) | Red - Off / On / Blinking | On / Blinking: Fault or warning active (TRIP / IMP). Off: Normal operation. |
Replacement and Spare Part Considerations
When replacing an installed Lenze EVF8221-E unit (part number 00400041), verify the original power rating (0.75 kW / 1.0 HP) and physical option module configuration. A replacement unit will not operate correctly out of the box without loading the machine-specific parameter set. Transfer the parameter configuration from the original drive using an E82ZBC Keypad XT module or restore a saved project file using Global Drive Control (GDC) software.
All plugged option modules—such as FIF I/O cards or AIF communication modules (e.g., EMF2133IB PROFIBUS)—must be removed from the faulty unit and seated properly in the replacement drive. Ensure fieldbus dip switches, node addresses, and bus termination settings are maintained. For long-term plant modernization, Lenze designates the i550 cabinet inverter series as the recommended successor line to the legacy 8200 Vector series.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short circuit / Earth fault | Excessive motor current caused by short circuit, ground fault, or excessive acceleration ramp. | Short circuit in motor cable, earth fault in motor windings, acceleration time set too short. | Check motor cable and insulation; check motor windings; increase acceleration time. |
| OC2 | Overcurrent during deceleration | Motor current exceeded trip threshold during braking/deceleration. | Deceleration time set too short, excessive load inertia without brake chopper/resistor. | Increase deceleration time; check brake resistor operation. |
| OC5 | Ixt overload | Inverter thermal overload limit reached (continuous overload). | Drive continuously operated above rated continuous output current. | Reduce motor load; check duty cycle and sizing of the inverter. |
| OH | Heatsink overtemperature | Inverter heat sink temperature exceeded maximum allowed limit. | Insufficient cooling airflow, dirty heatsink, cabinet fan failure, high ambient temperature. | Clean heatsink, ensure adequate cabinet ventilation, verify fan functionality. |
| OH4 | Motor thermal overload (PTC) | Motor temperature sensor (PTC/TK) connected to drive has triggered overtemperature fault. | Motor thermal overload, blocked motor shaft, defective motor fan. | Allow motor to cool, check mechanical load and motor cooling system. |
| OU | DC bus overvoltage | DC bus voltage exceeded safe maximum limit (e.g., >770 V DC). | Regenerative energy from motor during deceleration; deceleration time too short; brake resistor open/faulty. | Extend deceleration time; connect external brake resistor; check brake chopper settings. |
