Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9329-EPV004 is a 30 kW servo position controller from the 9300 Servo drive series. Designed for precision multi-axis positioning and synchronized motion control, this IP20-rated controller operates on a 3-phase AC line voltage ranging from 320 V to 528 V at 50/60 Hz. The drive delivers a continuous rated output current of 59 A and supports a maximum overload current of 88.5 A for up to 60 seconds, providing necessary dynamic performance for demanding industrial machinery. Featuring specialized positioning software integrated into the drive firmware, the EP variant generates motion profiles directly, making it suitable for packaging machinery, rotary indexing tables, and material handling axes.
Connecting and commissioning a replacement EVS9329-EPV004 requires establishing physical interfaces and matching software configurations. Motor feedback is handled via a Sub-D resolver input alongside master frequency encoder input and output connections operating at frequencies up to 500 kHz. Network integration is available through an integrated CANopen system bus running at up to 500 kbit/s, while an automation slot accepts option cards such as the EMF2133IB PROFIBUS, EMF2173IB DeviceNet, or EMF2102IB INTERBUS communication modules. Putting a replacement drive into service requires restoring parameter sets stored across four internal EEPROM memories using either the EMZ9371BC XT keypad module or Lenze Global Drive Control (GDC) software, a task where ABC Industrial Parts can support parameter backup and device setup.
Diagnostics and status indication are provided through onboard LED indicators and software monitoring tools. Operational status is indicated by a solid green LED for ready states and a solid red LED for TRIP fault conditions requiring reset. Diagnostic parameters, including the TRIP history log stored in parameter C0168, can be checked via GDC software or the keypad display. Standard troubleshooting steps include checking supply lines, power connections, encoder feedback, and motor thermal sensors. If an unserviceable control board error such as fault code H05 persists after cycling power, replacing the unit or sending it for repair through ABC Industrial Parts provides a rapid path back to full production.

Programming and Configuration
Configuration of the Lenze EVS9329-EPV004 is executed using Lenze Global Drive Control (GDC) software or the optional EMZ9371BC operating module (XT Keypad). GDC software enables real-time parameter configuration, positioning profile creation, and drive diagnostics over a PC connection.
The drive contains four internal switchable EEPROM parameter sets. These non-volatile memory areas store motor control settings, limit thresholds, and motion profiles. During replacement, saved parameter sets can be uploaded from the original unit and downloaded into the spare controller, avoiding manual reprogramming of positioning steps.
Communication and System Integration
The EVS9329-EPV004 features an integrated CANopen System Bus interface supporting data transfer rates up to 500 kbit/s. This bus allows high-speed communication between multiple 9300 series drives and higher-level automation controllers for synchronized multi-axis operations.
Additional fieldbus flexibility is provided through an integrated modular automation slot. Depending on network requirements, optional communication modules can be installed, including the EMF2133IB for PROFIBUS-DP, the EMF2173IB for DeviceNet, and the EMF2102IB for INTERBUS networks.
Diagnostics and Status Indication
Operational monitoring is facilitated via onboard LED indicators and parameter readouts. Operating states and fault messages can be evaluated through status words over fieldbus networks, the EMZ9371BC keypad display, or the GDC diagnostic monitor.
Detailed fault tracking is accessible via parameter C0168, which retains a log of recent TRIP events to assist in identifying recurrent electrical or mechanical issues.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready) | Green - Solid | Operational status / Drive enabled and ready for operation when continuously lit. |
| Red LED (TRIP / Fault) | Red - Solid | Fault indication / Drive tripped due to active fault or internal error requiring acknowledgment. |
Replacement and Spare Part Considerations
When swapping out a failed Lenze EVS9329-EPV004, ensure the replacement unit shares the exact model designation to match power ratings and integrated positioning firmware capabilities. Transfer any existing fieldbus communication modules from the original drive's automation slot to the replacement unit.
Because parameters are stored locally within internal EEPROM memory, a replacement drive will not operate correctly until the specific machine parameters are loaded. Use Global Drive Control software or the EMZ9371BC keypad module to transfer saved parameter sets to complete the installation.
