Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13324768 (Model EVS9324-ESV004) is a 3.0 kW servo drive within the Lenze 9300 Servo Inverter family, engineered for dynamic motion control and precision motor regulation. Operating from a 3-phase AC supply voltage between 320 V AC and 528 V AC, this unit delivers a continuous output current of 7 A at output voltages up to 480 V AC, supporting peak overload currents up to 10.5 A for 60 seconds. Powered by field-oriented vector control, it provides smooth torque generation and exact speed stability for both synchronous and asynchronous servo motors across applications in packaging lines, textile manufacturing, automotive assembly, and material handling indexing.
System connectivity on the EVS9324-ESV004 includes dedicated feedback terminals for resolvers on terminal X7 and incremental or Sin/Cos encoders on terminal X8, alongside integrated digital and analog control channels. Commissioning a replacement unit requires transferring machine-specific parameters, as the drive houses non-volatile EEPROM memory capable of retaining up to four independent parameter sets. Configuration and parameter transfer are carried out using Lenze Global Drive Control (GDC) software or the plug-in EMZ9371BC operating keypad module. Ensuring exact design variant matching with the V004 specification guarantees physical mounting and cooling compatibility when sourcing a replacement through ABC Industrial Parts.
Operational diagnostics are displayed directly on the unit via three front status LEDs indicating READY, pulse inhibit (IMP), and FAIL conditions. Detailed fault histories and live operating data are logged within parameter sub-indexes such as C0168 and accessible via GDC software, while internal TRIP/READY relay contacts relay fault status to supervisory controllers. Common trips caused by external factors—such as overvoltage (OU), undervoltage (LU), or overcurrent (OC1)—can usually be cleared by inspecting main power supplies, motor cables, or deceleration ramps. For internal hardware failures (H05) or memory errors (EEr), field repairs are not feasible, and replacing the drive with a fully tested unit from ABC Industrial Parts offers the most efficient solution to restore machine operation.

Programming and Configuration
The Lenze 13324768 EVS9324-ESV004 uses Lenze Global Drive Control (GDC) software for comprehensive commissioning, diagnostics, and parameter management. GDC enables maintenance personnel to tune speed controller gains (C0070 and C0071), set current limits, calibrate analog inputs and outputs, and configure motor feedback parameters. Manual parameter editing and drive status monitoring can also be performed directly at the machine using the removable EMZ9371BC operating keypad module, which attaches to the front of the drive.
Internal non-volatile EEPROM memory stores up to four separate parameter sets directly on the drive board. This multi-dataset architecture allows quick adaptation between different machine operating profiles or motor configurations without re-uploading files. When commissioning a new or restored unit from scratch, executing parameter C0002 resets the drive to factory default settings, ensuring a clean baseline before uploading application-specific parameters.
Communication and System Integration
Integrated multi-axis networking on the Lenze EVS9324-ESV004 is provided via the onboard CAN system bus connector (X14), which operates at transmission speeds up to 500 kbps. The CAN interface allows fast point-to-point and broadcast communication between multiple 9300 series drives and high-level motion controllers. Reliable communication over the CAN bus requires proper physical layer installation, including 120-ohm termination resistors applied at both ends of the network line.
In addition to the onboard CAN system bus, the drive features a front Automation Interface (AIF) slot to accommodate optional fieldbus communication modules. Installing modules such as the EMF2133IB PROFIBUS module or the EMF2178IB CANopen module enables integration into broader PLC environments, including PROFIBUS-DP, CANopen, INTERBUS, and LECOM networks. These expansion modules plug directly into the AIF slot, permitting real-time control word and process data exchange over main plant networks.
Diagnostics and Status Indication
The Lenze EVS9324-ESV004 features visual LED indicators on the front panel to signal real-time operating states. The green READY LED indicates active drive readiness, the yellow IMP LED signals active inverter pulse inhibit, and the solid red FAIL LED alerts operators to an active drive fault that has inhibited power output. A dedicated relay contact output provides external TRIP or READY signal status to high-level system monitoring equipment.
Detailed diagnostics are accessible via live monitoring parameters C0050, C0052, and C0053 using either GDC software or the EMZ9371BC keypad module. Active fault logs and historical trip data are stored within parameter sub-indexes under C0168. This fault history records specific event codes, enabling maintenance technicians to isolate root causes such as feedback signal loss, thermal overloads, or power supply fluctuations.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| FAIL | Red - Solid | Fault active (drive inhibited / error condition present) |
| READY | Green - Solid | Drive ready for operation / active |
| IMP | Yellow - Solid | Inverter pulse inhibit active (pulses blocked) |
Replacement and Spare Part Considerations
When replacing a Lenze 13324768 EVS9324-ESV004, confirm that the substitute matches both the power ratings (3.0 kW, 7 A) and the exact V004 design variant. The variant code designates structural, terminal, and cooling configurations necessary for direct cabinet mounting and thermal performance alignment.
Before putting a replacement unit into service, parameter backup files must be transferred from the original unit using Lenze GDC software or loaded via the EMZ9371BC keypad module. If the donor or faulty board is unpowered, component-level parameter extraction may be performed prior to installation. Any optional AIF communication modules (such as PROFIBUS EMF2133IB or CANopen EMF2178IB) must be moved to the new drive, verified for firm seating, and aligned with system fieldbus address settings.

Frequently Asked Questions
What software is used to commission and program the Lenze EVS9324-ESV004?
The drive is parameterized using Lenze Global Drive Control (GDC) software. Local parameter access and monitoring can also be completed using the plug-in EMZ9371BC operating keypad module.
How are parameters transferred to a replacement EVS9324-ESV004 servo drive?
Parameters can be saved and downloaded using Lenze GDC software or copied directly using the EMZ9371BC keypad module. Up to four parameter sets can be stored in the drive's internal non-volatile EEPROM.
Which fieldbus networks can be integrated with this drive?
The drive includes a standard CAN system bus via connector X14. Additional fieldbus networks, including PROFIBUS-DP (via EMF2133IB) and CANopen (via EMF2178IB), are supported by installing optional communication modules into the front Automation Interface (AIF) slot.
What does a solid red FAIL LED indicate on the front panel?
A solid red FAIL LED indicates an active fault condition that has inhibited the drive output stage. The specific cause can be diagnosed by checking parameter C0168 via GDC software or the EMZ9371BC keypad.
How should internal hardware faults such as H05 or persistent EEr errors be handled?
Fault EEr represents an EEPROM memory issue, which can sometimes be cleared by restoring factory defaults via parameter C0002. Persistent EEr errors and code H05 indicate internal control board or power section hardware faults that require professional repair or unit replacement.
