Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF9324-EVV100 is a 9300 Vector series frequency inverter designed for precise speed and torque control of three-phase AC asynchronous motors in industrial automation systems. Operating from a nominal three-phase supply voltage of 400 V AC to 480 V AC across a permissible range of 320 V AC to 528 V AC, this drive delivers a flexible dual power rating depending on the selected switching frequency. At an 8 kHz switching frequency, it provides a rated power output of 4.0 kW with a 9.5 A output current, whereas operating at 2 kHz or 4 kHz yields up to 5.5 kW with a 13.0 A output current. As a V100 variant intended for control cabinet installation, this unit is built without an integrated RFI filter, requiring external line filtering or mains chokes when installed in environments governed by EMC standards.
Connecting and configuring a replacement EVF9324-EVV100 requires attention to physical I/O wiring, network connections, and drive parameters. Control connections include six digital inputs, four digital outputs, two analog inputs, and two analog outputs, alongside an onboard CAN system bus interface operating via terminal connection X4 at speeds up to 500 kbps. The drive also features a modular Automation Interface (AIF) slot that accommodates communication adapters such as PROFIBUS-DP (EMF2133IB / EMF2131IB), LECOM RS-232/RS-485 (EMF2102IB / EMF2101IB), DeviceNet, or INTERBUS modules. Commissioning a spare unit involves loading the correct parameter set from non-volatile EEPROM memory, which holds up to four complete parameter profiles, or transferring configuration files using Lenze Global Drive Control (GDC) software or an EMZ9371BC operating keypad. ABC Industrial Parts can assist with parameter extraction from existing hardware to ensure a replacement unit matches original machine settings.
System status and operating faults are indicated on the front panel by two multi-status LEDs: a green Ready LED that illuminates solid when operational and blinks during controller inhibit, and a red Fault LED that flags active trip or warning conditions. Detailed diagnostic values, including real-time DC bus voltage, output current, frequency, motor speed, and module temperature, can be monitored through the GDC software, the EMZ9371BC keypad PRG/DSP menu, or the internal fault history memory storing the last eight trip codes. Basic troubleshooting includes verifying input mains balance for phase failure (LP1), inspecting motor cabling for short circuits or ground faults (OC1, OC2), checking 120 Ohm termination resistors on CAN networks (CE1), and inspecting heatsink fins for thermal warnings (OH). When internal power unit failures (H05) or EEPROM memory corruptions (EE) occur, board-level faults cannot be serviced in the field, making a tested replacement drive from ABC Industrial Parts or professional unit repair the standard route back to production.

Programming and Configuration
Programming and parameterization of the Lenze EVF9324-EVV100 9300 Vector inverter are primarily performed using Lenze Global Drive Control (GDC) commissioning software or the pluggable EMZ9371BC operating keypad module installed into the front AIF slot. The drive supports flexible control modes, including open-loop V/f characteristic control, sensorless vector control, and closed-loop vector control with encoder speed feedback for applications requiring dynamic torque and speed regulation.
Drive configuration data is stored within internal non-volatile EEPROM memory, which supports up to four distinct, complete parameter sets. This multi-parameter structure allows operators to switch between different machine operating profiles or retain factory default settings alongside custom user configurations. When parameter sets become corrupted or invalid, indicated by fault code PR0, restoring the default parameter set or re-uploading the project via GDC or the keypad is required to re-establish operational parameters.
Communication and System Integration
The EVF9324-EVV100 frequency inverter features an integrated system bus CAN interface accessible via terminal strip X4. Supporting data transmission rates up to 500 kbps, this onboard CAN bus enables multi-drive coordination and drive-to-drive synchronization across automated packaging, material handling, or conveying machinery without requiring external networking modules. Proper bus topology requires matching node ID settings, correct baud rate selection, and 120 Ohm termination resistors at both physical ends of the CAN cable.
For higher-level network integration, the drive includes a modular Automation Interface (AIF) slot. This expansion slot accepts fieldbus communication modules, including PROFIBUS-DP adapters (EMF2133IB or EMF2131IB) and LECOM serial interface modules (EMF2102IB or EMF2101IB for RS-232/RS-485 communication), as well as INTERBUS and DeviceNet options. Loss of communication between the main control board and an installed AIF fieldbus option triggers fault code CE0, signaling the need to verify module seating and cable integrity.
Diagnostics and Status Indication
The drive provides status monitoring through two LED indicators located on the front face, as well as digital diagnostic data accessible via system registers and GDC software. Real-time feedback parameters include DC bus voltage, output frequency, motor current, calculated or feedback motor speed, and heatsink temperature. An internal memory log maintains a history buffer of the last eight fault conditions, allowing technicians to analyze trip history during root-cause investigations.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready (Green) | Green - Solid / Blinking | Inverter is powered and ready for operation; blinking indicates controller inhibit active |
| Fault / Error (Red) | Red - Solid / Flashing Code | Drive fault trip condition present. On steady or flashing code indicates active TRIP/warning state |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVF9324-EVV100 inverter, service technicians must confirm the specific model suffix and hardware configuration. As a V100 variant, this drive does not feature an internal RFI filter. If replacing a standard unit or installing into an installation governed by EN 61800-3 EMC standards, external line filters and mains chokes must be verified and retained in the control cabinet wiring.
A replacement unit cannot be operated directly out of the box without transferring the drive setup. All parameter settings—including motor electrical data, control mode (V/f, sensorless, or closed-loop encoder feedback), I/O function assignments, and CAN node parameters—must be written to the replacement drive's EEPROM. This can be accomplished by inserting a pre-configured EMZ9371BC keypad from the original drive or downloading the project file using Lenze GDC software. Fieldbus cards such as PROFIBUS (EMF2133IB / EMF2131IB) or LECOM (EMF2102IB / EMF2101IB) must also be transferred from the original unit to the replacement slot.

Frequently Asked Questions
What is the power output rating of the Lenze EVF9324-EVV100?
The inverter provides a dual power rating: 4.0 kW with a 9.5 A rated output current at an 8 kHz switching frequency, or up to 5.5 kW with a 13.0 A output current when configured for 2 kHz or 4 kHz switching frequencies.
Does the EVF9324-EVV100 include an integrated RFI filter?
No, the V100 variant is manufactured without an internal RFI interference suppression filter. External EMC filters or mains chokes must be installed in the control cabinet when compliance with EN 61800-3 is required.
What fieldbus networks are supported by the EVF9324-EVV100?
The unit includes an onboard CAN system bus interface via terminal X4. Additional fieldbus protocols, including PROFIBUS-DP (via EMF2133IB / EMF2131IB modules), LECOM RS-232/RS-485 (via EMF2102IB / EMF2101IB modules), INTERBUS, and DeviceNet, are supported using the modular Automation Interface (AIF) slot.
How do I transfer parameters to a replacement drive?
Parameters can be transferred using Lenze Global Drive Control (GDC) software connected via a LECOM adapter, or by attaching an EMZ9371BC operating keypad containing the original drive's parameter settings stored in EEPROM memory.
What does fault code OC1 indicate on the drive?
Fault code OC1 indicates an output overcurrent or short circuit on the motor terminals. Common causes include a short circuit in the motor cable or motor winding, an excessively short acceleration ramp time, or a defective motor.
What action should be taken if fault code H05 appears?
Fault code H05 indicates an internal power unit or gate driver circuit hardware fault. This internal failure cannot be serviced in the field and requires drive repair or replacement of the unit.
