Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13267644 EVS9329-EP is a 45 kW servo drive belonging to the Lenze 9300 Servo series, engineered for high-power dynamic positioning and speed regulation in industrial motion applications. Operating on a three-phase supply voltage ranging from 320 V AC to 528 V AC at 45 Hz to 65 Hz, the drive delivers a rated continuous output current of 89 A with a peak output capability of 133.5 A and a maximum output frequency of 480 Hz. Featuring built-in Extended Positioning (EP) control, this servo inverter allows positioning programs, point-to-point sequences, and homing routines to run directly on the drive without requiring a separate PLC positioning controller.
System connectivity is provided through an integrated CANopen system bus interface, 6 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs, along with dedicated terminal connections for resolver (X7) and encoder feedback (X8). An optional Automation Interface (AIF) slot accepts fieldbus modules such as EMF2133IB PROFIBUS or EMF2191IB Ethernet cards. Commissioning a replacement unit involves transferring the machine-specific parameter set (PAR1 through PAR4) and positioning profile data onto the replacement drive using Lenze Global Drive Control (GDC) software V4.x+ or an EMZ9371BC Keypad XT module. When replacing a failed unit, matching parameter configurations and firmware requirements is essential to restore proper operational state, and ABC Industrial Parts can assist with tested replacement drives and configuration transfers.
The drive features three front status LEDs indicating operational readiness (solid green Power/Ready), active TRIP fault conditions (solid or blinking red Fault), and current limiting or warning thresholds (solid yellow Warning). Diagnostic codes can be retrieved on the Keypad XT via parameter C0003 or monitored in real time using GDC software. Fault conditions such as OC1 (short circuit), OU (DC bus overvoltage), LU (DC bus undervoltage), CE0/CE1 (communication errors), and EE0 (EEPROM memory error) highlight clear diagnostic paths, whereas internal logic failures such as H05 signal board-level errors that are not field-serviceable. For hardware failures requiring immediate action, ABC Industrial Parts provides tested exchange units and repair options to bring production machinery back online quickly.

Programming and Configuration
The EVS9329-EP features integrated Extended Positioning (EP) firmware that allows motion block commands, positioning targets, homing reference routines, and sequence profiles to be configured directly within the drive. Motion parameters and parameter sets (PAR1 through PAR4) are managed using Lenze Global Drive Control (GDC) PC software version 4.x or higher, connected via fieldbus or direct communication interfaces.
Commissioning or replacing a drive requires loading stored parameter files into the replacement unit to ensure matching acceleration profiles, velocity loop gain settings, and positioning block tables. Alternatively, parameter replication can be completed using the plug-in EMZ9371BC Keypad XT module, which allows direct parameter set cloning without requiring a PC connection on the factory floor.
Communication and System Integration
Inter-drive communication and control system integration are supported via the built-in CANopen / Lenze System Bus interface accessible at connector X4. Operating with configurable baud rates and standard 120-ohm termination resistors, this bus enables high-speed synchronization across multiple drive axes and real-time parameter exchange.
Expansion for high-level fieldbus architectures is accomplished through the integrated Automation Interface (AIF) slot. The drive accepts optional AIF communication cards, including EMF2133IB PROFIBUS-DP, EMF2191IB Ethernet, and Interbus modules, integrating the drive into diverse PLC-driven automation networks.
Diagnostics and Status Indication
Diagnostic evaluation on the EVS9329-EP is facilitated by three status LEDs located on the front panel, providing immediate status feedback for power, active TRIP conditions, and thermal or current warnings. Detailed fault diagnostics and trip history memory are accessible via Keypad XT code C0003, or through real-time oscilloscope and monitoring tools within Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Power | Green - Solid | Ready for operation / Power ON |
| Fault | Red - Solid / Blinking | Fault active (TRIP condition) |
| Warning | Yellow - Solid | Warning active / current limit reached |
Replacement and Spare Part Considerations
When replacing an existing Lenze 13267644 EVS9329-EP drive, ensure that the incoming three-phase supply (320–528 V AC) and motor feedback connections at terminals X7 (resolver) or X8 (encoder) match the original wiring configuration. Check that optional plug-in modules, such as AIF fieldbus cards (EMF2133IB or EMF2191IB), are correctly transferred to the replacement drive's expansion slot.
A replacement drive will not operate in the machine until parameter sets PAR1 through PAR4 and positioning profile sequences are copied from the original unit or backup repository. Verify that parameter memory (EEPROM) is correctly written and perform a homing routine to confirm target positioning boundaries before resuming automatic operation.
