Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00411350 (model EVF8211-E) is a panel-mounted frequency inverter from the Lenze 8200 Vector product family, designed for precise motor speed regulation in automated machine environments. Operating with a rated output power of 0.75 kW, this compact drive accepts a flexible single-phase or three-phase supply voltage ranging from 180 to 264 V AC. It provides a three-phase output of 0 to 230 V AC with a continuous output current rating of 4.0 A and carries an IP20 protection rating. Supporting both V/f characteristic control and sensorless vector control, the unit delivers dynamic starting torque and accurate speed regulation across an output frequency range up to 480 Hz, making it well-suited for applications in material handling, packaging machinery, pumps, and blowers.
For system integration and commissioning, the EVF8211-E incorporates a pluggable Front Function Interface slot that accepts dedicated fieldbus communication modules, including CANopen, PROFIBUS-DP, DeviceNet, Interbus, and LECOM serial interfaces. Parameterization is managed on-site using the Keypad XT module (EMF2101IB) or through a PC running Lenze Global Drive Control software. Internal non-volatile EEPROM storage retains four independent parameter sets, enabling rapid switching between distinct operating profiles via digital inputs or fieldbus commands. When putting a replacement drive into service, the existing communication module and stored parameter profiles must be transferred from the original unit to align with machine settings, a process where ABC Industrial Parts can assist through parameter extraction and backup support.
Diagnostic information is indicated directly on the front panel via LED indicators, including a red fault LED for active error states and a green ready LED for normal operation and controller inhibit monitoring. Comprehensive fault identification and live operational monitoring—including DC bus voltage, output current, and operating frequency—are accessible through the Keypad XT display or the software fault history buffer. Operational faults cover overcurrent conditions during acceleration (OC1), deceleration (OC2), or steady operation (OC3), DC bus overvoltage (OU) or undervoltage (LU), thermal overload (OH, OH4, OH7), and communication errors (CE0, CE1). While external wiring or parameter issues can be resolved during routine maintenance, internal component self-test failures such as H05 indicate hardware-level issues that require repair or a fully tested exchange unit from ABC Industrial Parts to restore production.

Programming and Configuration
Drive setup for the Lenze 00411350 EVF8211-E frequency inverter is executed either via the Keypad XT (EMF2101IB) plug-in unit or using PC-based Lenze Global Drive Control (GDC) software. GDC software allows commissioning technicians to configure control modes, set custom V/f characteristic curves, adjust acceleration and deceleration ramps, and fine-tune sensorless vector control parameters. The software also provides an integrated oscilloscope tool for real-time signal analysis during motor commissioning.
The drive features internal non-volatile EEPROM memory capable of holding four separate parameter sets. This multi-configuration capability allows operators to switch operational profiles dynamically for different product runs using digital inputs or fieldbus commands. When replacing a unit, parameter backup files created in GDC software or saved on a Keypad XT can be downloaded directly into the spare inverter to replicate exact motor tuning and control logic.
Communication and System Integration
The EVF8211-E inverter incorporates a front-accessible modular function interface (FIF slot) designed for plug-and-play network integration. This slot accepts a range of optional communication modules, including CANopen (EMF2171IB and EMF2172IB), PROFIBUS-DP (EMF2133IB), DeviceNet, Interbus, and LECOM RS232/RS485 serial interfaces.
The modular hardware design separates the power and core inverter electronics from the fieldbus communication layer. When integrating into a fieldbus architecture such as CANopen or PROFIBUS, network address settings and bus termination must be configured on the plug-in module. Communication failures between the drive control board and the automation module trigger specific system alarms, ensuring reliable bus status monitoring.
Diagnostics and Status Indication
Real-time operational status on the EVF8211-E is provided by two status LEDs mounted on the front panel. A solid green LED indicates normal operation, while a flashing green LED indicates controller inhibit. A solid red LED illuminates during an active error state to alert operators to a system trip.
For detailed diagnostic analysis, the Keypad XT module displays clear-text fault codes and operational parameter values. Alternatively, Lenze Global Drive Control software provides direct access to a diagnostic buffer containing fault history, along with live monitoring of DC bus voltage, output current, switching frequency, and motor operating status.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Fault / Störung | Red - Solid | Illuminated during active error state |
| Ready / Betrieb | Green - Solid / Flashing | Illuminated during normal operation; blinks during controller inhibit |
Replacement and Spare Part Considerations
The Lenze EVF8211-E (00411350) is designed as a compact, panel-mounted drive within the 8200 Vector series. When replacing an existing unit in a control cabinet, technicians must confirm that the spare matches the original power rating of 0.75 kW and voltage specification (180–264 V AC input, 0–230 V AC output). Mechanical mounting spacing should follow standard cooling clearances to maintain sufficient airflow through the IP20 enclosure.
A replacement unit requires transferring the existing communication module (such as PROFIBUS or CANopen) from the FIF slot of the original drive to the replacement drive, along with loading the original parameter set via GDC software or Keypad XT. For legacy machine upgrades where an exact replacement is evaluated against newer platforms, Lenze designates the i550 series (successor part i55AE175B0001000S) as the migration path, which involves reviewing cabinet dimensions, wiring, and fieldbus configuration.
