Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00488632 EVS9324-EI is a panel-mounted servo inverter from the 9300 Servo product family, engineered for precise speed-controlled motion applications across automated production environments. Delivering a rated power output of 5.5 kW, this drive operates on a 3-phase supply voltage ranging from 320 V AC to 528 V AC. It provides a continuous output current of 13 A with a peak current capacity of 19.5 A and output voltage from 0 to 480 V AC. Housed in an IP20 enclosure for cabinet mounting, the drive features an integrated signal processor running a speed-controlled (-EI) software architecture to deliver dynamic velocity regulation in conveyor systems, continuous packaging feeds, material handling, and textile processing.
Connecting the EVS9324-EI to control systems and feedback devices is supported by flexible physical interfaces. Motor feedback connects via connector X7 for resolvers or connector X8 for encoder feedback and master frequency inputs, with connector X9 supplying encoder frequency output for multi-axis coupling. Inter-drive coordination is handled natively through an onboard CAN system bus operating up to 500 kbit/s on connector X4. Additional network integration is achieved using the modular Automation Interface (AIF) slot, which accepts PROFIBUS-DP, CANopen, EtherCAT, or LECOM communication modules. Commissioning a replacement unit requires transferring application data stored in non-volatile EEPROM memory, which holds up to four parameter sets and can be managed using the Keypad 9371BB or Global Drive Control software. ABC Industrial Parts can assist maintenance teams with tested replacement units and parameter transfer procedures to minimize operational downtime.
System state tracking and fault identification are facilitated by status LEDs and diagnostic software functions. Front-panel LEDs indicate operational readiness, controller disable states, active TRIP conditions, and system errors. Diagnostic memory buffer code C0168 logs TRIP history, while real-time codes display DC bus voltage, motor current, output frequency, and heatsink temperature. Standard trip causes such as overcurrent (OC1), earth faults (OC2), or DC bus overvoltage (OU) can be resolved through external checks. Internal hardware faults indicated by code H05 or simultaneous blinking status LEDs represent non-field-serviceable failure modes where drive repair or a tested exchange unit from ABC Industrial Parts offers the most reliable route back to full operation.

Programming and Configuration
Programming and configuring the Lenze EVS9324-EI servo inverter is accomplished using Lenze Global Drive Control (GDC) software or directly via the pluggable Keypad 9371BB module. The drive contains internal non-volatile EEPROM memory configured to store up to four complete parameter sets. This flexible memory structure allows users to store tailored velocity control parameters, motor thermal limits, acceleration and deceleration ramps, and terminal assignment mappings.
During routine maintenance or complete drive replacement, saved configuration files can be uploaded or downloaded via GDC software, or cloned directly from drive to drive using the Keypad 9371BB module. In events where memory corruption occurs, indicated by parameter fault code PR0, restoring operational baseline settings can be performed through factory reset code C0002 before re-applying saved application parameters.
Communication and System Integration
The EVS9324-EI provides robust communication options for multi-axis machinery and complex control topologies. Integrated into the main unit is an onboard CAN system bus on connector X4, capable of high-speed inter-drive communication up to 500 kbit/s. Master-slave synchronization and frequency transmission are further enabled through feedback connector X8 for master frequency or encoder input, and connector X9 for encoder frequency output.
For integration into broader industrial fieldbus networks, the drive features a modular Automation Interface (AIF) slot. This expansion port accommodates various plug-in communication modules including PROFIBUS-DP (EMF2133IB / 2112IB), CANopen (2130IB), EtherCAT (2175IB), and LECOM serial adapters. Proper network operation requires verifying bus line termination, such as 120-ohm resistors on CAN networks, and ensuring physical module alignment inside the AIF slot.
Diagnostics and Status Indication
Status feedback on the EVS9324-EI is provided through front-panel LED indicators and diagnostic data registers. Two primary LEDs, labeled DRIVE READY and DRIVE ERROR, convey the operational condition of the inverter, enabling technicians to rapidly identify normal operating modes, active controller inhibits, warnings, fault trips, or board-level failures.
For in-depth troubleshooting, diagnostic parameters monitored through Lenze Global Drive Control (GDC) software or the Keypad 9371BB display operational data in real time. Key variables accessible via parameter codes include DC bus link voltage, output phase current, output frequency, and heatsink temperature. Additionally, historical fault data is retained in a TRIP buffer accessible via code C0168.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid | Normal operation (drive operational and ready) |
| DRIVE READY | Green - Blinking | Controller inhibit / disable state active |
| DRIVE ERROR | Red - Solid | Active TRIP condition (drive shut down due to fault) |
| DRIVE ERROR | Red - Blinking | Active warning / TRIP-set state |
| DRIVE READY & DRIVE ERROR | Green/Red - Simultaneous Blinking | Internal system fault or hardware failure requiring factory repair |
Replacement and Spare Part Considerations
When replacing a installed Lenze EVS9324-EI unit, care must be taken to match the continuous power rating (5.5 kW), output current capacity (13 A), and speed-controlled (-EI) drive firmware variant. Physical mounting requirements demand appropriate cabinet clearance to accommodate the 220 W power dissipation and maintain proper airflow through the cooling fins.
Because a replacement unit does not contain your machine's custom settings out of the box, parameter restoration is required before operation. Field service personnel should transfer the complete parameter set from the original drive using either the Keypad 9371BB module or Lenze Global Drive Control (GDC) software. Any optional expansion modules installed in the Automation Interface (AIF) slot—such as PROFIBUS or EtherCAT cards—must also be transferred to the spare inverter, and network addresses confirmed before restarting the process.
