Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8211-E is a compact frequency inverter within the 8200 Series family, engineered for precise speed and torque control of three-phase AC motors rated at 0.75 kW. Operating on a 3-phase mains supply voltage of 400 V to 480 V AC (with an operating voltage range of 320 V to 550 V AC at 45 to 65 Hz), this drive delivers up to 2.4 A of continuous output current with a maximum output voltage of 480 V AC. Featuring an IP20 protection enclosure, the unit supports both linear or quadratic V/f characteristic control and sensorless vector control modes across an output frequency range of 0 to 480 Hz with an 8 kHz switching frequency.
Integrating a spare drive into an existing control system requires aligning drive parameters and network options to match the original application. The EVF8211-E features an integrated automation slot that accepts plug-in fieldbus extension cards—including the EMF2133IB PROFIBUS-DP, EMF2173IB CANopen, and LECOM modules—alongside the EMZ8201BB keypad operating module. Parameterization and commissioning can be managed using Lenze Global Drive Control (GDC) software or directly via the handheld keypad. Internal non-volatile EEPROM memory stores up to four complete parameter sets, allowing saved drive configurations to be transferred efficiently to replacement units to restore machine operation. ABC Industrial Parts can assist with sourcing compatible replacement units and parameter handling options.
Diagnostic information is made available directly on the front panel and through parameter registers. Dual status LEDs provide immediate feedback: a solid green LED indicates normal operation with the controller enabled, a blinking green LED signals ready status with controller inhibit active, and a solid red LED indicates an active TRIP fault state. When equipped with an EMZ8201BB keypad module, specific fault codes such as OC1 (short circuit), OU (DC bus overvoltage), or LU (undervoltage) are displayed, while historical trip data can be retrieved from parameter registers C0168 and C0170. If diagnostics point to internal board failures, such as internal thermal sensor fault OH7 or control hardware fault H05, board-level repairs or a fully tested exchange drive from ABC Industrial Parts provide a reliable path to resume production.

Programming and Configuration
Drive setup and parameter management for the Lenze EVF8211-E are accomplished using Lenze Global Drive Control (GDC) engineering software or the plug-in EMZ8201BB keypad module. Parameters govern critical operational behaviors including acceleration and deceleration ramp times (parameters C0012 and C0013), motor current limits, and thermal monitoring settings such as parameter C0075 for I2t motor protection.
The inverter features non-volatile EEPROM memory capable of storing up to four complete parameter sets simultaneously. This multi-dataset architecture allows alternate operating configurations to be maintained within a single drive. During commissioning or unit replacement, stored configurations can be uploaded via GDC software or keypad modules to replicate original machine settings without requiring manual re-entry. Factory default settings can be restored when necessary by executing parameter reset code C0002=1.
Communication and System Integration
The EVF8211-E utilizes a modular communication interface centered around an integrated automation slot. This slot accepts dedicated fieldbus communication modules to integrate the inverter into higher-level industrial automation networks. Supported options include the EMF2133IB module for PROFIBUS-DP networks, the EMF2173IB module for CANopen fieldbus systems, and LECOM communication interfaces.
Network modules allow the drive to receive speed references, control commands, and enable signals directly from a master controller or PLC, while transmitting real-time operating data and fault conditions back to the network. When integrating a replacement drive onto a fieldbus, network station addresses, bus termination, and communication timeout parameters (monitored via communication trip code CE0) must be matched to the existing system architecture.
Diagnostics and Status Indication
The drive includes front-panel LED status indicators and parameter-based diagnostic monitoring tools. Visual indication is provided by status LEDs: the green LED shows operational readiness or active drive operation, while the red LED alerts operators to active TRIP conditions. Detailed diagnostic lookup is available through keypad module EMZ8201BB or software access to fault history memory registers C0168 and C0170.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready / Operation) | Green - Solid / Blinking | Solid green indicates controller enabled and drive running; Blinking green indicates drive ready with power on and controller inhibit active. |
| Red LED (TRIP / Fault) | Red - Solid | Continuous red indicates an active TRIP fault state. |
Replacement and Spare Part Considerations
Replacing a legacy Lenze EVF8211-E 8200 Series inverter requires ensuring exact hardware identity and parameter replication. Because the EVF8211-E drives motor behavior based on application-specific parameter settings stored in memory, installing a replacement unit without transferring settings will result in improper drive behavior or fault conditions.
Before putting a spare drive into operation, transfer parameter sets from the original drive using the EMZ8201BB keypad memory transfer function or Global Drive Control (GDC) software. Fieldbus cards such as the EMF2133IB PROFIBUS-DP or EMF2173IB CANopen module must be moved from the original drive to the replacement unit or configured with identical node addresses and termination settings. Checking power connections, motor wiring insulation, and control terminal jumper settings prior to applying mains voltage prevents damage and ensures system compatibility.
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 | Short circuit on output terminal phases or ground fault during acceleration/operation | Short circuit in motor cable or motor windings; phase-to-phase insulation failure | Check motor wiring and insulation, test motor windings, check drive output terminals for shorts |
