Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8221-E is a cabinet-mounted AC frequency inverter belonging to the 8200 Vector product family. Built for controlling standard three-phase AC induction motors, this drive delivers 15 kW (20 HP) of motor power with an output current rating of 32 A at 400 V AC and 27 A at 480 V AC, operating across an input voltage range of 320 V AC to 528 V AC at 50/60 Hz. Designed with an IP20 protection enclosure, the unit supports both open-loop and closed-loop vector control alongside configurable V/f characteristic curves, providing speed and torque regulation for machinery such as conveyors, pumps, fans, packaging units, and textile processing equipment.
Connecting and integrating the EVF8221-E into an automated architecture relies on its integrated Function Module Interface (FIF) slot, which accepts pluggable modules for network integration and expanded control. Options include the E82ZAFCC CANopen module, the E82ZAFPC PROFIBUS-DP module, and the E82ZAFSC LECOM RS-232/RS-485 module. When installing a replacement unit, drive parameterization is required prior to operation. The internal EEPROM memory stores dual parameter sets (PAR1 and PAR2), enabling parameter extraction and duplication using either an EMZ8201BB or E82ZBC keypad operating module or Lenze Global Drive Control (GDC) software. Support from ABC Industrial Parts can assist in sourcing matched replacements or managing parameter migration to minimize machine downtime during drive installation.
Diagnostic information is available directly on the front panel via LED status indicators and pluggable keypad interfaces. A solid green READY / OPERATION LED indicates normal operation, while a solid or flashing red FAULT / TRIP LED signals an active fault condition. In addition to visual indications, detailed error tracking can be accessed via diagnostic parameters C0168 and C0169 through GDC software or keypad displays. Fault codes such as OC1 (short circuit), OU (DC bus overvoltage), and LU (DC bus undervoltage) point to field wiring, supply, or braking issues, whereas codes like EE01 or H05 signify internal board or memory faults. If board-level errors persist after power cycles and factory resets, sending the unit to ABC Industrial Parts for testing or exchanging it for a field-ready replacement provides a reliable path back to full production.

Programming and Configuration
Commissioning and parameter adjustments on the Lenze EVF8221-E are performed using Lenze Global Drive Control (GDC) software or handheld keypad modules such as the EMZ8201BB or E82ZBC. The drive relies on an internal non-volatile EEPROM memory that maintains dual parameter sets, PAR1 and PAR2. This dual-structure configuration allows users to store alternate motor profiles or rapidly clone working parameter values from a functioning unit onto a replacement drive.
Key configuration parameters manage essential motor performance and protection limits. Critical adjustments include parameter C0012 for setting acceleration ramp times, C0013 for setting deceleration ramp times, and C0032 for specifying the maximum output frequency up to 480 Hz. Switching frequency is adjustable between 2.5 kHz and 16 kHz (with a default of 8 kHz), allowing technicians to strike an optimal balance between thermal losses and motor noise reduction. To clear corrupt settings or restart setup from a known baseline, setting parameter C0002 to 1 reloads the factory default profile.
Communication and System Integration
The EVF8221-E utilizes a modular hardware design featuring a Function Module Interface (FIF) slot located on the front of the main drive chassis. This slot accepts dedicated communication and function cards, allowing the drive to interface directly with fieldbus networks and central PLC automation systems without requiring a complete drive replacement.
Supported fieldbus modules include the E82ZAFCC System Bus CANopen module, the E82ZAFPC PROFIBUS-DP module, and the E82ZAFSC LECOM RS-232/RS-485 serial module. Installing or swapping these modules requires switching off power, seating the module firmly into the FIF slot, and ensuring correct shielding and grounding practices to prevent communication drops or interference errors.
Diagnostics and Status Indication
The drive provides continuous status feedback via front panel LEDs, pluggable keypad displays, and internal error logs accessible through GDC software. Status indicators supply immediate visual feedback regarding drive readiness and fault conditions during routine operation.
For deeper diagnostic evaluation, the drive logs historical fault events in diagnostic parameters C0168 and C0169. These records can be read directly using an EMZ8201BB keypad module or via software connected over a LECOM or CAN bus communication module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| FAULT / TRIP | Red - Solid / Flashing | Inverter fault or trip condition active |
| READY / OPERATION | Green - Solid | Drive ready or in normal operation |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVF8221-E frequency inverter, ensure that the incoming three-phase supply line voltage match the required operating range of 320 to 528 V AC. A direct unit replacement requires transferring the existing pluggable function module (such as the E82ZAFCC or E82ZAFPC) from the old unit to the replacement drive to preserve network connectivity.
Parameters stored in the internal EEPROM must be downloaded from the original drive or uploaded from a backed-up profile using Global Drive Control (GDC) software or an EMZ8201BB / E82ZBC keypad. For system upgrades or complete line retrofits, the contemporary Lenze i550 cabinet frequency inverter series serves as the recommended modern successor series.
