Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8214-E is a 3-phase AC frequency inverter drive from the 8200 vector series, designed for variable frequency speed and torque control in industrial automation applications. Operating across a supply voltage range of 320 V to 528 V AC at 45 to 65 Hz, this drive provides a nominal output rating of 3.0 kW (7.3 A continuous current) at 400 V AC and 4.0 HP (6.1 A continuous current) at 480 V AC. It supports standard V/f characteristic speed regulation and sensorless vector control, managing output frequencies from 0 to 480 Hz with switching frequencies up to 16 kHz. Rated for a power dissipation of 120 W and featuring a 150% peak overload capacity up to 11.0 A for 60 seconds, the drive is utilized in mechanical systems including industrial conveyors, material handling, pumps, packaging machinery, and fans.
Designed with a modular hardware structure, the EVF8214-E isolates its base power electronics from control and network interfaces via detachable slots. The Automation Interface (AIF) slot supports optional fieldbus modules such as PROFIBUS-DP, CANopen, DeviceNet, INTERBUS, and LECOM RS232/RS485, while the Function Interface (FIF) slot accommodates standard or application-specific I/O modules. Non-volatile onboard EEPROM memory allows storage of up to four independent, switchable parameter sets. Commissioning or installing a replacement unit requires transferring stored parameter profiles and setting interface communications, which can be accomplished using the plug-in EMZ8201BB keypad control module or Lenze Global Drive Control (GDC) PC software. When replacing a damaged unit, parameter extraction from donor drives or configuration transfers can be supported by ABC Industrial Parts to restore operational parameters prior to system start-up.
Operational status monitoring and diagnostic detection are handled through onboard indicators and connected tools. The front panel includes status LEDs—a green Ready/Operation LED and a red Trip/Fault LED—supported by parameter code monitoring via Code C0003 for fault history and Code C0183 for active faults. Typical trip codes include DC link undervoltage (LU), overvoltage (OU), input phase failure (LP1), overcurrent events (OC1 through OC5), and heatsink overtemperature (OH). When basic checks of mains voltage supply lines, motor insulation, and communication cabling do not clear an error, persistent fault codes such as EEPROM failure (EER) or internal error (H05) point to control board or power section faults. Because internal hardware components are not field-serviceable, sending the drive for repair or securing a tested exchange unit through ABC Industrial Parts provides a straightforward path to restoring production.

Programming and Configuration
The Lenze EVF8214-E drive uses an integrated non-volatile EEPROM storage system capable of holding up to four independent, switchable parameter sets. Commissioning, tuning, and parameter setup are conducted using Lenze Global Drive Control (GDC) software or locally via the plug-in EMZ8201BB keypad control module. The keypad module allows direct modification of parameter codes and enables direct cloning of complete parameter profiles between drive units without requiring a computer.
Parameter adjustments are managed through code addresses designated for monitoring and operational configuration. Setting Code C0002 restores factory default parameters to resolve corrupted memory states. Key control settings include Code C0011 for maximum speed regulation, Code C0012 for acceleration ramp times, and Code C0013 for deceleration ramp times. Proper calibration of acceleration and deceleration ramps helps prevent overcurrent conditions (OC2, OC3) and DC bus overvoltage trips (OU) during dynamic motion cycles.
Communication and System Integration
System connectivity on the EVF8214-E is established through a dual-slot modular architecture comprising an Automation Interface (AIF) slot and a Function Interface (FIF) slot. The AIF slot accommodates fieldbus interface modules, allowing the inverter to communicate directly with master PLCs and plant automation networks. Compatible plug-in modules include the EMF2133IB for PROFIBUS-DP, EMF2171IB and EMF2172IB for CANopen system bus integration, and EMF2102IB for LECOM RS232/RS485 communication, alongside DeviceNet, INTERBUS, and Modbus RTU options.
The Function Interface (FIF) slot accepts I/O modules for local digital and analog control signals required in standalone machinery or distributed control setups. For CAN system bus communication, proper bus topology requires 120-ohm termination resistors at physical cable endpoints and matching baud rates across all network nodes. Process and parameter data transfers across the AIF slot are actively monitored by configurable timeout parameters (CE1, CE2) to ensure reliable automated operation.
Diagnostics and Status Indication
The EVF8214-E features diagnostic functions provided by front panel status LEDs, keypad diagnostic codes, and PC software monitoring tools. The front panel includes two LED indicators that display primary operational states: the green Ready/Operation LED signals an active operating state when illuminated continuously and a controller inhibit state when blinking, while the red Trip/Fault LED turns solid during an active fault trip and blinks during warning states.
Detailed trip diagnostics can be retrieved using the EMZ8201BB keypad module or Global Drive Control (GDC) PC software. Code C0183 displays the currently active trip code, while Code C0003 records historical fault events. This allows maintenance technicians to identify input power disturbances, motor overloads, thermal trips, or fieldbus communication timeouts quickly during field troubleshooting.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Trip / Fault LED | Red - OFF / ON / Blinking | OFF = Normal operation; ON = Active trip condition / fault present; Blinking = Active warning condition |
| Ready / Operation LED | Green - ON / Blinking | ON = Inverter enabled and operating; Blinking = Inverter ready, controller inhibit active |
Replacement and Spare Part Considerations
As part of the legacy Lenze 8200 vector series, which has been discontinued by the manufacturer, replacing an EVF8214-E unit requires ensuring electrical rating matches and transferring interface modules. A direct replacement must support 320 V to 528 V AC input supply voltage and match the continuous output ratings of 7.3 A at 400 V or 6.1 A at 480 V. Installed plug-in fieldbus modules (AIF slot) and functional I/O modules (FIF slot) must be moved from the original drive to the replacement chassis to maintain network connectivity.
Before placing a replacement unit into active operation, parameter configurations must be cloned from the original unit using the EMZ8201BB keypad module or uploaded via Lenze Global Drive Control (GDC) software. Transferring saved parameter profiles restores motor limit settings, acceleration/deceleration ramps, and fieldbus node parameters. For facilities undertaking long-term modernization, direct functional upgrades from the legacy 8200 vector series can also be accomplished using the Lenze i550 cabinet frequency inverter series.
