Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00484758 EVS9323-ESV004 is a 1.5 kW servo drive from the Lenze 9300 Servo series, engineered for high-dynamic positioning, electronic gearing, and multi-axis servo applications. Operating on a 3-phase mains supply from 400 V AC to 480 V AC (with an allowable input range of 320 V AC to 528 V AC), this unit delivers up to 3.9 A continuous output current across an output frequency range of 0 to 480 Hz at an 8 kHz switching frequency. Designed as the V004 variant, it integrates built-in safe torque off and safety stop circuitry directly into the drive module, reducing external safety hardware and control cabinet wiring.
Interfacing the drive into an existing control system relies on its dual Sub-D 15-pin motor feedback ports for resolver or Sin/Cos encoder signals, along with an onboard CANopen and Lenze System Bus interface supporting communication rates up to 500 kbps. Expansion is handled via an Automation Interface (AIF) slot, which accepts plug-in modules such as the PROFIBUS-DP module (EMF2133IB / EMF2131IB), LECOM RS232/RS485 module (EMF2102IB), or Keypad XT (EMF2133IB). Commissioning a replacement unit requires transferring machine parameter sets stored using Lenze Global Drive Control (GDC) software V4.x/V5.x or copied via the Keypad XT module. When replacing a failed unit, backup parameter restoration ensures correct drive commissioning and motor tuning before placing the spare into production, with technical assistance available from ABC Industrial Parts for extracting parameters from existing setups.
System diagnostics are communicated through status LEDs on the front panel, where a solid green READY LED confirms normal power supply and drive operation, while a solid red TRIP LED indicates an active drive fault that has shut down the power stage. Detailed error tracking is available through the GDC software diagnostic window and history log or via the error display on an attached Keypad XT. Common operational faults include OC1 (output short circuit), OC5 (Ixt current overload), OU (DC bus overvoltage), and CE0 (system bus communication failure). Standard checks should verify incoming line power on terminals, cabling insulation, bus termination, and cooling airflow. Unresolved internal board errors such as H05 or persistent EER memory corruption point to internal hardware damage that cannot be serviced in the field, making unit replacement or repair through ABC Industrial Parts the quickest solution to resume operation.

Programming and Configuration
The Lenze EVS9323-ESV004 servo drive utilizes Lenze Global Drive Control (GDC) PC software (versions V4.x and V5.x) for parameterization, commissioning, and system monitoring. The drive supports up to four internal parameter sets, enabling flexible recipe switching and multi-axis task management within automated machinery.
Parameters can be uploaded, edited, and saved to PC storage via GDC, or transferred directly using the optional Keypad XT (EMF2133IB) plug-in module. When replacing an existing unit, loading the saved parameter file into the non-volatile memory of the replacement drive ensures identical control behavior, motor feedback scaling, and safety system configuration.
Communication and System Integration
For drive-to-drive synchronization and system control, the EVS9323-ESV004 features an onboard CANopen and Lenze System Bus interface supporting data transfer rates up to 500 kbps. This integrated bus allows rapid exchange of motion commands and velocity profiles between multiple Lenze 9300 drives without needing external network master cards.
System flexibility is extended through an Automation Interface (AIF) slot located on the front of the unit. This slot accommodates optional fieldbus communication modules, including the PROFIBUS-DP adapters (EMF2133IB / EMF2131IB) and LECOM RS232/RS485 serial communication modules (EMF2102IB), enabling straightforward integration into standardized PLC architectures.
Diagnostics and Status Indication
Front-mounted status LEDs offer immediate visual feedback on the operating condition of the drive. The green READY LED remains continuously illuminated when internal power supplies are within normal operating thresholds, while the red TRIP LED turns solid to signal an active fault condition that has disabled the output power stage.
Comprehensive diagnostic assessment is supported through the diagnostic window and error history buffer in Lenze Global Drive Control (GDC) software, as well as error code readouts on the Keypad XT module display.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| READY | Green - Solid | Drive controller power supply active and operating normally |
| TRIP | Red - Solid | Active drive fault state (TRIP condition); internal or external trigger halted output stage |
Replacement and Spare Part Considerations
When sourcing a replacement for a Lenze 00484758, verify that the replacement unit matches the full model designation EVS9323-ESV004. The V004 suffix designates the integrated safety stop circuit, which must be present to maintain safety compliance and control panel wiring alignment.
A replacement drive cannot run directly out of the box without transferring the original application parameter sets. Before swapping hardware, back up all four parameter sets using Lenze Global Drive Control (GDC) software or a Keypad XT module. Once installed, verify bus node addresses, baud rates, fieldbus module seating in the AIF slot, and encoder connections on the dual Sub-D ports prior to applying high-voltage mains power.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit | Short circuit or ground fault detected on motor output phase lines. | Motor cable damaged, motor winding short circuit, or output transistor damaged. | Check motor and wiring for insulation fault; if cabling is good and fault persists immediately upon power-up, internal power module is damaged (return for repair). |
| OC5 | Ixt Overload | Drive continuous overload current exceeded threshold for allowed time limit. | Excessive mechanical load, acceleration ramp too steep, motor undersized. | Check mechanical drive train, reduce acceleration rates, or verify drive capacity. |
| OU | Overvoltage DC Bus | DC bus voltage exceeded upper limit switch threshold. | Excessive regenerative energy during deceleration, brake chopper resistor missing or defective. | Increase deceleration time or install external braking resistor. |
| LU | Undervoltage DC Bus | DC bus voltage dropped below minimum operating limit. | Mains supply voltage drop, phase loss, power supply failure. | Check supply voltage mains supply fuses and incoming AC lines. |
| OH | Overtemperature Heatsink | Heatsink temperature exceeded allowable operating limit. | Inadequate cabinet ventilation, dirty heatsink cooling fins, ambient temperature too high, fan failure. | Clean heatsink, inspect enclosure cooling fans and ambient air flow. |
| OH4 | Overtemperature Motor | Motor temperature sensor active (PTC or thermal contact trigger). | Motor thermal overload, thermal sensor cable broken or disconnected. | Allow motor to cool, check thermal sensor connection terminals T1/T2. |
| CE0 | System Bus Communication Error | Communication interruption or error on CAN System Bus network. | Bus cable disconnected, incorrect baud rate, missing termination resistor. | Inspect CAN cabling, verify bus termination switches and node IDs. |
| EER | EEPROM Memory Error | Corrupted or unreadable internal non-volatile EEPROM parameter data. | Internal EEPROM hardware failure or power loss during parameter writing. | Internal hardware/memory fault — attempt factory reset; if persistent, return unit for repair or replace unit. |
| H05 | Internal Hardware Error | Internal control board self-test failure detected during startup. | Board-level microcode error or internal hardware fault. | Internal hardware failure — replace unit or return for factory service. |
