Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00411351 EVF8212-E is a compact 0.75 kW frequency inverter belonging to the 8200 vector series, engineered for IP20 control cabinet mounting. Operating on an AC supply range of 180 V to 264 V at 45 to 65 Hz, this drive provides a continuous rated output current of 4.0 A with a peak dynamic capacity supporting up to 150% overload current (6.0 A for 60 seconds). The unit features flexible motor control modes, including high-torque sensorless vector control and programmable linear or quadratic V/f characteristics. With an output frequency range of 0 to 480 Hz and a standard factory switching frequency of 8 kHz (adjustable up to 16 kHz), the drive delivers high motor responsiveness and smooth speed regulation for conveyor drives, variable speed pumps, fans, and packaging equipment.
For communication and system integration, the EVF8212-E features an integrated CAN system bus operating at speeds up to 500 kbps, along with an onboard option slot for pluggable function modules such as PROFIBUS-DP (EMF2133IB or EMF2131IB) and LECOM-B RS485 (EMF2102IB). Commissioning a replacement unit requires transferring application parameters, as a spare drive will not operate correctly without the proper configuration. Drive setup and cloning are executed via Lenze Global Drive Control (GDC) software or the optional Lenze XT Keypad (EMZ8201BB), which can store up to four parameter sets in non-volatile onboard EEPROM. When parameter extraction from a damaged drive presents challenges, ABC Industrial Parts can assist technicians with parameter transfer and configuration recovery to get replacement units running quickly.
Diagnostics and real-time status monitoring on the EVF8212-E are provided through front panel status LEDs and software display registers. A green Operation LED signals normal standby (blinking) or active drive operation (solid), while a red Fault / TRIP LED alerts operators to an active fault state. Fault diagnosis is supported by internal register C0183 for current status and a four-location fault history buffer (C0168/1 to C0168/4). Common field issues include output short circuits (OC1), DC bus overvoltage (OU), and heatsink overtemperature (OH). While supply line drops or motor wiring shorts can be resolved on site, internal component faults such as EEPROM failure (EER) or power board faults (H05) require specialized repair; in these situations, factory repair or a fully tested exchange drive from ABC Industrial Parts offers a fast path back to production.

Programming and Configuration
Parameterization of the Lenze 00411351 EVF8212-E frequency inverter is carried out using Lenze Global Drive Control (GDC) software or the optional plug-in Lenze XT Keypad (EMZ8201BB). The inverter features non-volatile onboard EEPROM storage capable of retaining up to four complete parameter sets. This multi-set capability simplifies parameter cloning across identical machine configurations and speeds up spare part installation.
Key parameter configurations include acceleration ramp time (C0012), deceleration ramp time (C0013), and adjustable switching frequencies up to 16 kHz. If parameter memory becomes corrupted or requires a full reset during commissioning, setting parameter C0002 to 1 restores the unit to factory default settings, after which motor parameters and dynamic control settings can be reloaded.
Communication and System Integration
The EVF8212-E integrates an onboard CAN system bus interface capable of network speeds up to 500 kbps. This integrated system bus supports master/slave drive synchronization and multi-drive networking. Physical connections require standard 120 Ohm bus termination resistors installed at both end nodes of the CAN line to ensure reliable data transmission.
To communicate across alternative industrial networks, the inverter features a dedicated option slot for interchangeable function modules. Supported expansion modules include the PROFIBUS-DP card (EMF2133IB / EMF2131IB) and the LECOM-B RS485 module (EMF2102IB). Proper seating of these function cards is essential; a poor interface connection will trigger communication fault CE0.
Diagnostics and Status Indication
Visual status indication is provided directly on the front panel by dual LED indicators. The green Operation LED blinks to indicate normal standby status and remains solid green when the drive is enabled and actively driving the motor. The red Fault / TRIP LED illuminates solid or blinks whenever an active fault condition or TRIP status is detected.
Detailed troubleshooting is supported via parameter display registers. Operating status can be verified using code C0183, while historical fault data is recorded in a four-location error buffer (C0168/1 to C0168/4). Accessing this buffer via the XT Keypad or GDC software allows technicians to identify recurring overcurrent, overvoltage, or thermal issues.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Fault / TRIP | Red - Solid or Flashing | Active fault condition or TRIP status |
| Operation | Green - Blinking or Solid | Blinking indicates normal standby operation; solid indicates drive is enabled and running |
Replacement and Spare Part Considerations
Before replacing an existing drive with a spare Lenze 00411351 EVF8212-E, verify that the replacement match matches the 0.75 kW power rating and 180–264 V AC input requirements. Any communication options installed in the existing unit—such as PROFIBUS-DP or LECOM modules—must be transferred to the option slot of the replacement drive prior to powering up.
Because the EVF8212-E relies on stored parameters for motor control, application ramps, and fieldbus communication, installing an unconfigured spare will result in drive faults or unexpected machine behavior. Back up parameters from the original drive using GDC software or the XT Keypad (EMZ8201BB) and transfer the complete parameter set to the replacement unit.
For long-term system planning on legacy equipment, the Lenze i550 cabinet inverter series is designated as the recommended successor platform. When maintaining existing control cabinets without system re-engineering, replacing faulty units directly with matching 00411351 spare parts ensures immediate physical and functional compatibility.

Frequently Asked Questions
What tools are required to transfer parameters to a replacement Lenze EVF8212-E drive?
Parameters can be transferred using Lenze Global Drive Control (GDC) software via a PC connection or directly using the plug-in Lenze XT Keypad (EMZ8201BB). Up to four parameter sets can be saved in the onboard non-volatile EEPROM for cloning across drives.
What causes an OC1 fault on the Lenze 00411351 inverter?
An OC1 code indicates a short circuit or earth fault on the motor output terminals. This can be caused by damaged motor insulation, a short in the motor power cable, a ground fault, or excessive cable capacitance. Inspect motor cables, connection terminals, and winding insulation.
How do the front LEDs indicate drive status on the EVF8212-E?
The green Operation LED blinks during normal standby and stays solid green when the drive is enabled and running. The red Fault / TRIP LED lights up solid or flashes during an active fault or TRIP condition.
Can the Lenze EVF8212-E drive connect to PROFIBUS or RS485 networks?
Yes, while the base unit includes an integrated CAN system bus, fieldbus networking such as PROFIBUS-DP (EMF2133IB / EMF2131IB) or LECOM-B RS485 (EMF2102IB) can be added by installing the corresponding module into the front option slot.
What is the recommended successor model for the legacy Lenze 8200 vector EVF8212-E drive?
The Lenze i550 cabinet inverter series is recommended as the successor platform when upgrading legacy systems utilizing the 8200 vector series.
