Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9325-CKV003 is a 5.5 kW servo controller from the 9300 Servo family, specifically designed as a 9300 Servo Cam Profiler unit with integrated V003 application firmware. Operating on a nominal 400 V AC 3-phase supply with an allowable voltage range of 320 to 528 V AC, this IP20-rated drive delivers a continuous rated current of 13 A and a peak output current of 19.5 A at an 8 kHz switching frequency. Its cold-plate mounting design dissipates heat through external cooling surfaces or heat sinks, keeping electrical enclosure cabinet dimensions compact.
Interfacing the unit with external machinery relies on a Sub-D 9-pin resolver connection, master frequency and encoder inputs, as well as simulated encoder outputs for synchronized multi-axis control. Communication across drive systems is driven by an onboard System Bus CAN interface, supplemented by an Automation Interface (AIF) slot that supports option cards such as the EMF2133IB PROFIBUS-DP or EMF2173IB CANopen modules. When commissioning a replacement unit, parameter sets stored in the original controller must be loaded into the spare unit using Lenze Global Drive Control (GDC) software or the plug-in EMZ9371BC keypad module. Because the onboard firmware executes electronic cam profiles directly, aligning software parameters, motor feedback calibration, and module addresses is required to ensure proper operation. Technical specialists at ABC Industrial Parts can assist in parameter extraction and configuration verification when replacing operational drives.
Diagnostic conditions are reported via two front-facing LEDs: a green DRIVE READY status indicator that remains solid during normal operation and a red DRIVE ERROR / TRIP LED that flashes or stays solid when a fault is active. Detailed error conditions, such as short circuits (OC1), DC link overvoltage (OU), motor feedback errors (SD7), or electronic cam tracking errors (P12), can be examined through the EMZ9371BC keypad display or monitored remotely using GDC software and the internal trip history buffer. While external issues such as cable faults, line phase losses, or parameter errors can be resolved during routine maintenance, unresolvable system errors like internal hardware failures (H05) or severe EEPROM corruption (EEr) indicate internal component defects. In these cases, contacting ABC Industrial Parts for a tested exchange unit or professional repair service helps restore production quickly.

Programming and Configuration
The EVS9325-CKV003 servo controller operates using integrated V003 Cam Profiler application firmware, allowing complex electronic camming functions and synchronized motion sequences to execute directly within the drive logic. Parameterization and system commissioning are conducted through Lenze Global Drive Control (GDC) software connected via serial LECOM or fieldbus interfaces, or locally using the plug-in EMZ9371BC operating keypad module with its 8-character display.
The drive memory structure supports up to four complete, independent parameter sets stored internally. Transferring parameter data to a spare unit during drive replacement requires retrieving the active configuration via GDC software or backing up the parameter file from the original controller. Re-establishing feedback scaling, resolver pole configurations, and motion control tolerance bands is necessary before restoring power to the system output stage.
Communication and System Integration
System-level integration for the Lenze EVS9325-CKV003 is driven by its integrated System Bus CAN interface, which provides direct drive-to-drive inter-axis synchronization and rapid parameter exchange across multi-axis motion networks. Physical connections require 120-ohm bus termination resistors at both physical ends of the communication line to ensure network integrity.
For high-level industrial fieldbus integration, the unit includes an Automation Interface (AIF) front expansion slot. This slot accepts option cards such as the EMF2133IB for PROFIBUS-DP networks and the EMF2173IB for CANopen protocols, as well as modules for LECOM RS-232/RS-485 and Interbus. Additionally, the drive provides 5 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs for direct wiring to localized machine sensors and control signals.
Diagnostics and Status Indication
The EVS9325-CKV003 provides visual and digital diagnostic reporting to streamline troubleshooting. Front-panel LED status indicators offer immediate feedback on operating states, while detailed numerical trip codes are transmitted to the EMZ9371BC keypad display or logged inside the drive internal trip history memory buffer accessible through Lenze GDC software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid | Operational state indication; solid illuminated when drive controller is initialized and ready for operation. |
| DRIVE ERROR / TRIP | Red - Flashing / Solid | Fault indication; flashing or solid illuminated when a drive fault or trip condition is active. |
Replacement and Spare Part Considerations
When substituting an existing Lenze EVS9325-CKV003 servo controller, maintenance teams must verify that the cold-plate mounting surface is properly prepared with suitable thermal conduction compound or mounted flush against compatible cooling plates. Physical dimensions and the IP20 enclosure rating require adequate cabinet space and proper heat exchange to prevent thermal trips.
Because motion profiles and axis synchronization parameters are stored in internal non-volatile memory, a replacement unit cannot function out of the box without parameter transfer. Operating teams must ensure that motor resolver feedback connections, fieldbus module seating in the AIF slot, and network baud rate configurations match the original installation prior to enabling the drive output.
