Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00470806 EVS9325-ES is a 5.5 kW servo inverter from the 9300 Servo series, designed for high-precision motor speed, torque control, and synchronized motion applications. Operating on a 3-phase AC supply ranging from 320 V AC to 528 V AC, this drive supplies a rated output current of 13 A with a 150% peak overload capacity reaching 19.5 A for up to 60 seconds. Featuring an IP20 protection rating and an 8 kHz switching frequency, the inverter delivers high dynamic positioning response for multi-axis machinery, electronic shafting, and master-slave gear synchronization.
Connecting a replacement unit into an existing line requires matching feedback interfaces and communication setups. The EVS9325-ES provides Sub-D 9-pin inputs for standard resolvers and Sub-D 15-pin connections for incremental or SinCos absolute encoders, along with 5 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. Communication is provided onboard via a CAN system bus operating up to 500 kbps, supplemented by a multi-pin Automation Interface (AIF) slot that supports fieldbus modules such as EMF2133IB PROFIBUS-DP, EMF2175IB CANopen, INTERBUS, or LECOM adapters. Drive parameterization relies on internal EEPROM memory capable of holding up to four complete, switchable parameter sets, which can be extracted from a donor board or transferred directly using an EMZ9371BC keypad or Lenze Global Drive Control (GDC) software. Technical support for parameter extraction and drive commissioning is available through ABC Industrial Parts.
Visual operational status is supplied directly through front-panel LEDs, including Green (DRIVE READY / POWER), Red (DRIVE ERROR / TRIP), and Yellow (IMPULSE INHIBIT / WARNING), as well as a fail-safe TRIP relay output contact and CAN bus status word monitoring. System trip codes like OU for DC bus overvoltage, LU for DC bus undervoltage, LP1 for input phase loss, and feedback faults Sd2 or Sd3 isolate external power and wiring issues. Internal electronic failures, such as EE0 EEPROM corruption or H05 hardware faults, indicate board-level failures that cannot be repaired in the field, making unit replacement or off-site repair through ABC Industrial Parts the ideal solution to restore machine uptime.

Programming and Configuration
Configuration and commissioning of the Lenze 00470806 EVS9325-ES are performed using Lenze Global Drive Control (GDC) software or the pluggable EMZ9371BC operating keypad. The drive stores parameter settings in non-volatile internal EEPROM memory, accommodating up to four distinct, switchable parameter sets. This internal storage structure allows complete drive setups to be backed up, modified, or restored without loss of configuration during main power interruptions.
When putting a replacement inverter into service, parameter sets can be copied from the original drive using the EMZ9371BC keypad or uploaded and downloaded via GDC software over a serial or fieldbus connection. Proper alignment of parameter configurations, motor feedback parameters, and current limit thresholds is necessary to ensure correct positioning accuracy, speed loop stability, and control interface behavior.
Communication and System Integration
The EVS9325-ES comes equipped with an onboard CAN system bus interface capable of communication speeds up to 500 kbps. This integrated bus allows fast multi-axis data exchange, real-time status word monitoring, master-slave frequency coupling, and electronic gearbox synchronization across interconnected 9300 Servo drives.
For broader fieldbus integration, the unit features a modular Automation Interface (AIF) slot. This slot accepts optional communication adapters, including the EMF2133IB PROFIBUS-DP module and the EMF2175IB CANopen module, as well as INTERBUS and RS-232/RS-485 LECOM adapters. External system control is further supported through 5 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs.
Diagnostics and Status Indication
Diagnostic monitoring on the Lenze 00470806 EVS9325-ES is provided through three front-panel status LEDs, diagnostic readouts on the EMZ9371BC keypad, real-time diagnostic windows within Global Drive Control (GDC) software, and CAN bus status words. A fail-safe TRIP relay switch contact also opens to alert high-level system controllers when a fault condition shuts down the drive.
The status LEDs deliver instantaneous status updates regarding power supply activation, active fault trips, and control inhibit states to facilitate quick initial checks.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY / POWER | Green - Solid | Drive operational status and power supply active |
| DRIVE ERROR / TRIP | Red - Solid / Flashing | Drive trip fault or critical error detected |
| IMPULSE INHIBIT / WARNING | Yellow - Solid / Flashing | Impulse inhibit active or warning limit reached |
Replacement and Spare Part Considerations
When replacing a Lenze 00470806 EVS9325-ES servo inverter, verify that the replacement matches the exact model number and electrical ratings, specifically the 5.5 kW power rating and 13 A continuous current capacity. Ensure that any installed optional modules, such as AIF fieldbus communication cards (e.g., EMF2133IB or EMF2175IB), are transferred to the replacement unit prior to power-up.
Because drive behavior relies on application-specific settings, parameter sets saved in the original drive's EEPROM must be transferred to the replacement unit using the EMZ9371BC keypad or Global Drive Control software. Check feedback wiring on Sub-D terminals X7 and X8, as well as CAN network termination resistors and node address settings, to ensure proper synchronization upon restart.
