Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9324-ETV907 is a 3.0 kW servo drive controller from the Lenze 9300 Series, specifically belonging to the 9300 Servo PLC family. Designed to integrate IEC 61131-3 compliant motion and logic control directly inside the drive housing, this compact IP20 unit operates on a 3-phase mains supply from 320 V AC to 528 V AC (400/480 V AC nominal). It delivers a continuous output current of 7.0 A and a peak output current capability of 10.5 A at an 8 kHz chopping switching frequency. The V907 hardware variant suffix designates a cold-plate mounting construction, which dissipates heat through a flat contact surface to an external heatsink or cabinet wall rather than relying on standard integrated fan fins.
Connecting and replacing an EVS9324-ETV907 requires careful attention to both software project alignment and physical interface options. The controller features onboard digital inputs and outputs (8 inputs, 4 outputs), analog channels (2 inputs, 2 outputs), a universal feedback interface supporting resolvers, TTL, SinCos, and Hiperface encoders, and an onboard CANopen system bus operating at speeds up to 500 kbps. Expansion into higher-level fieldbuses is handled via the Automation Interface (AIF) slot, which accepts plug-in communication modules such as the EMF2133IB PROFIBUS module or EMF2192IB EtherCAT module. Replacing a unit is not a simple plug-and-play process; technicians must transfer both drive parameters and the compiled IEC 61131-3 PLC application project using Lenze Global Drive Control (GDC) or Drive PLC Developer Studio (DDS), or via an EMF2102IB Keypad XT. When project files are inaccessible from a damaged drive, ABC Industrial Parts can assist in parameter extraction and configuration recovery from legacy memory structures.
For operational monitoring and troubleshooting, the drive housing provides direct visual diagnostics through three status LEDs: a solid green LED for power and ready state, a solid or flashing yellow LED for operating warnings such as current limits, and a solid or flashing red LED indicating a fault trip condition that disables drive outputs. Detailed diagnostic data, real-time CAN registers, and a stored fault history log are accessible through the GDC diagnostic window or DDS online monitoring. Common trip conditions include DC bus overvoltage (OU), motor overtemperature (OH4), and system bus errors (CE1), which can often be solved by inspecting network termination resistors or cooling setups. However, unrecoverable codes such as internal system failure (FAIL) or control board diagnostic failure (H05) signal non-field-serviceable hardware damage. In these cases, sourcing a fully tested exchange unit or utilizing rapid repair services from ABC Industrial Parts offers the most reliable pathway to minimize machinery downtime.

Programming and Configuration
The Lenze EVS9324-ETV907 integrates full IEC 61131-3 programmable logic control into the drive electronics, allowing complex multi-axis motion and machine control logic to run directly on the drive unit. System setup and logic development are performed using Lenze Drive PLC Developer Studio (DDS), which supports standard programming languages including Ladder Diagram, Function Block Diagram, and Structured Text. Parameter adjustments and drive commissioning are managed separately or concurrently through Lenze Global Drive Control (GDC) software.
When commissioning a replacement controller, both the motion parameters and the active PLC runtime program must be loaded into the drive non-volatile memory. Parameter backup and download can also be executed directly at the machine using the optional EMF2102IB Keypad XT module. Ensuring that the PLC program version, communication settings, and motor feedback parameterization match the machine exact operational requirements is essential prior to enabling the drive stage.
Communication and System Integration
The EVS9324-ETV907 includes a built-in CANopen system bus interface operating at speeds up to 500 kbps. This integrated bus facilitates fast, deterministic multi-axis synchronization and electronic shaft or electronic cam functions between linked 9300 series drives without overburdening a central controller. Proper bus architecture requires 120-ohm termination resistors at both physical ends of the CAN network and correct node ID addressing.
To integrate with host control systems and higher-level automation networks, the drive features a dedicated Automation Interface (AIF) slot. This modular slot accommodates plug-in communication cards including the EMF2133IB for PROFIBUS-DP, EMF2192IB for EtherCAT, as well as modules for INTERBUS and LECOM RS232/RS485. During unit replacement, the AIF card from the original unit can be swapped into the replacement drive, provided address switches and fieldbus configurations are properly configured.
Diagnostics and Status Indication
Visual status feedback is provided on the front panel by three status LEDs. The green LED indicates power and ready status, glowing solid during normal active operation. The yellow LED illuminates or flashes during warning states, such as when current limits or thermal thresholds are reached. The red LED illuminates or flashes when a fault trip condition occurs, immediately disabling inverter output power to protect the drive and motor.
Advanced diagnostic feedback is accessed electronically via the EMF2102IB Keypad XT, the GDC diagnostic window, or DDS online status registers. Internal memory maintains a fault history log recording recent trip events. Network communications can also read CANopen system bus status registers and AIF communication states to pinpoint network interface drops or synchronization errors.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Power/Ready) | Green - Solid | Drive active / controller ready for operation; normal operating state |
| Red LED (Fault) | Red - Solid/Flashing | Drive fault trip condition present; outputs disabled until fault is reset |
| Yellow LED (Warning) | Yellow - Solid/Flashing | Warning condition present (e.g., current limit reached, thermal warning) |
Replacement and Spare Part Considerations
When replacing an installed Lenze EVS9324-ETV907, verifying the physical cooling interface is critical. The V907 hardware variant features a cold-plate flat backplate designed to transfer heat directly to an external cooler or enclosure mounting surface. Replacing a V907 unit with a standard heatsink-and-fan model will result in thermal or mechanical mounting mismatches inside the control cabinet.
Before putting a spare drive into service, technicians must transfer both the operating parameters and the compiled IEC 61131-3 PLC program from the original unit or project archives using GDC or DDS. Additionally, any installed AIF expansion card (such as PROFIBUS or EtherCAT) must be transferred to the spare unit, verifying that node addresses, baud rates, and encoder feedback settings (whether resolver, TTL, SinCos, or Hiperface) match the existing installation.
