Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF9323-EVV004 is a 1.5 kW frequency inverter belonging to the 9300 Vector series, engineered for high-dynamic motor control and speed regulation in industrial automation installations. Designed to operate on a 3-phase mains supply between 320 V AC and 528 V AC, this AC drive delivers a rated output current of 3.9 A with an overload capacity of up to 150% (5.85 A) for 60 seconds. The V004 designation identifies a specific hardware configuration manufactured without an integrated RFI filter, making it ideal for installation in control panels that utilize dedicated external line filtering. It supports Sensorless Vector Control, Field-Oriented Control (FOC), and programmable V/f characteristic curves to regulate standard three-phase AC motors across dynamic load profiles.
Interfacing options on the EVF9323-EVV004 include an onboard CAN system bus supporting communications up to 500 kbps, alongside an integrated automation slot for modular fieldbus cards. Physical I/O terminals provide 6 parameterisable digital inputs, 1 controller enable input, 4 digital outputs, 2 bipolar analog inputs, and 2 analog outputs. Commissioning a replacement inverter into an active machine requires matching the application configuration, function block assignments, and parameter settings of the existing unit. Parameter transfer can be performed directly using the optional EMZ9371BC operating keypad or via Global Drive Control (GDC) PC software. Parameter extraction from a faulty donor unit and pre-configuration support available through ABC Industrial Parts help streamline spare-part installation and reduce unexpected machine downtime.
System diagnostic evaluation is supported through hardware status LEDs and software status monitoring. Front panel LEDs provide immediate operational status, with a green Ready LED indicating drive readiness or active running status, and a red TRIP LED signaling protective shut-off conditions. Internal status parameter C0168 logs active fault states, while the integrated fault history buffer stores recent events for diagnostic review. Issues such as overcurrent (OC1, OC2, OC5), mains phase loss (LP1), or DC bus overvoltage (OU) can often be resolved through external checks on wiring, braking modules, or ramp settings. When internal component defects or unrecoverable hardware trips occur, board-level repairs or replacing the unit with a tested exchange inverter from ABC Industrial Parts offers a swift return to full operation.

Programming and Configuration
Parameterization and functional programming of the Lenze EVF9323-EVV004 inverter are performed using standard Lenze software tools or plug-in keypad hardware. The drive features an open control structure using interconnectable function blocks, which allow engineers to program speed control loops, torque limits, dynamic acceleration profiles, and custom input/output mappings directly within the drive firmware.
Commissioning or replacing a drive unit requires transferring the parameter dataset from the original drive or engineering backup file. Using the optional EMZ9371BC keypad module, complete parameter profiles can be cloned directly between drive units without a PC. Alternatively, the Global Drive Control (GDC) software tool connects via system bus adapters to read, edit, transfer, or back up parameter sets. Restoring default operational conditions is accomplished by executing a factory reset via parameter C0002 (set to value 11).
Communication and System Integration
The EVF9323-EVV004 is equipped with a native CAN / Lenze system bus interface capable of communication speeds up to 500 kbps. This integrated bus allows high-speed peer-to-peer data interchange between multiple 9300 Vector drives, facilitating multi-axis synchronization and master-slave drive configurations across a shared CAN line.
For integration into broader plant networks, the drive includes a dedicated automation slot that accepts modular fieldbus communication cards. Supported modules include the EMF2133IB PROFIBUS-DP card, EMF2102IB or EMF2103IB LECOM interfaces (RS232/RS485), and EMF2171IB or EMF2172IB PC system bus adapters, allowing connection to higher-level programmable logic controllers.
Diagnostics and Status Indication
Visual status indication on the Lenze EVF9323-EVV004 inverter is provided by front-mounted diagnostic LEDs. The Ready LED indicates the general operating state, while the TRIP LED alerts operators to protective drive shutdowns caused by overcurrent, overvoltage, motor overtemperature, or system communications errors.
Detailed diagnostic analysis is available through drive software parameters. Active errors are displayed in parameter C0168, and historical error events are stored within an internal fault history buffer. These diagnostic registers can be queried via the EMZ9371BC keypad or through real-time diagnostic monitoring in the Global Drive Control (GDC) software suite.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| TRIP LED | Red - Solid or Flashing | Inverter TRIP error state / Fault condition active. Indicates drive shut down due to protective fault function. |
| Ready LED | Green - Flashing = Ready; Solid = Running | Inverter operational status indicator. Flashing indicates drive is ready/operational; solid green indicates drive is enabled/running. |
Replacement and Spare Part Considerations
When replacing an existing drive with a Lenze EVF9323-EVV004, ensure that the part number and variant matches the installation requirement. The V004 model is built without an integrated RFI filter; replacing an unfiltered drive with a unit containing an internal filter (or vice versa) can alter cabinet EMC performance or physical wiring clearance.
A replacement EVF9323-EVV004 will not run directly out of the box without configuration. Machine parameter values, motor nameplate data, I/O functions, and fieldbus communication settings must be transferred from the original inverter or restored from a software backup before enabling the drive.
If the original drive hardware is damaged or unresponsive, parameter sets can be written using GDC software over the system bus interface or cloned using the plug-in EMZ9371BC keypad from a matching donor unit on the same machine line.
