Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9323-EP is a 3.0 kW 9300 Series servo position controller designed for high-performance single-axis and multi-axis positioning applications. Operating across a 3-phase mains supply voltage range of 320 V AC to 528 V AC at 45 to 65 Hz, this servo controller delivers a continuous output current of 7 A at an 8 kHz switching frequency, with a peak output current capability of 10.5 A for up to 60 seconds. The drive generates an output voltage from 0 to 400 V AC with a maximum output frequency of 480 Hz and power dissipation of 140 W. Equipped with vector control functionality, the unit integrates a dedicated Sub-D resolver feedback interface alongside a secondary Sub-D port for incremental encoders or digital frequency bus connections.
Integrating a replacement EVS9323-EP into an existing automation system requires matching external fieldbus infrastructure and transferring device settings. The controller features an integrated Lenze System Bus (CANbus) interface supporting data transmission rates up to 500 kbit/s for inter-drive coordination. A modular Automation Interface (AIF) slot accommodates optional fieldbus adapters, including the PROFIBUS-DP module (EMF2133IB), DeviceNet module (EMF2173IB), and INTERBUS module (EMF2111IB). Commissioning and parameter transfer are carried out using Global Drive Control (GDC) software or the Keypad XT operating unit (EMZ9371BC). Up to four complete, non-volatile parameter sets can be stored in the drive's internal EEPROM, allowing parameter configuration to be copied to a spare unit. Technical assistance for extracting parameter sets or verifying module integration is available through ABC Industrial Parts.
Diagnostic monitoring on the EVS9323-EP is provided by front-panel status LEDs alongside code displays on the optional Keypad XT and internal fault registers accessible via CANbus or GDC using code C0168. A green Ready LED signals standby or operational status, while a red TRIP LED indicates active warnings or fault trips. Common operational trips include overvoltage (OU), undervoltage (LU), output short circuit (OC1), overcurrent during acceleration (OC5), heat sink over-temperature (OH), motor thermal overload (OH4), and communication loss (CE0, CE1). When internal system errors such as EEPROM corruption (PEE, EER) or board-level hardware failures (H05) occur, field repairs are generally not feasible. In these instances, sourcing a fully tested exchange drive or scheduling specialized repair through ABC Industrial Parts provides a direct route to restoring machine operation.

Programming and Configuration
The Lenze EVS9323-EP supports parameter assignment and motion programming through Lenze Global Drive Control (GDC) software or directly via the plug-in Keypad XT (EMZ9371BC) operator panel. Operating parameters, velocity loop settings, and positioning limits are organized within structured code directories. Drive reset and factory parameter restore operations are initiated using code C0002 to re-establish default operational profiles.
The servo controller contains non-volatile internal EEPROM memory capable of retaining up to four complete parameter sets. This multi-dataset architecture allows operators to store alternative production profiles or maintain a reliable backup directly on the device. Parameter data can be uploaded to GDC software or copied into a Keypad XT unit for direct transfer into a replacement servo drive during field maintenance.
Communication and System Integration
System integration on the Lenze EVS9323-EP relies on built-in interfaces and modular fieldbus options. The integrated Lenze System Bus (CANbus), accessible via terminal X4, operates at communication speeds up to 500 kbit/s, enabling high-speed inter-drive synchronization and master-slave coordination across multi-axis positioning systems. Physical bus lines require 120-ohm termination resistors at each physical end of the network.
An Automation Interface (AIF) slot on the front of the drive accepts optional plug-in modules to connect with higher-level industrial networks. Supported network interfaces include PROFIBUS-DP (EMF2133IB), DeviceNet (EMF2173IB), and INTERBUS (EMF2111IB). Motor feedback connections are established using a Sub-D connector for resolver units and a separate Sub-D port configured for incremental encoder feedback or digital frequency bus synchronization.
Diagnostics and Status Indication
The EVS9323-EP features dual LED indicators on the front housing to provide real-time status indication during operation and troubleshooting. Detailed fault tracking is supported via code C0168 in the internal fault history register, accessible through GDC software or the Keypad XT module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Blinking / Solid / Off | Blinking = Drive ready/standby; Solid = Controller enabled and running; Off = Power off or fault condition |
| TRIP | Red - Solid / Blinking | Solid Red = Fault trip active (if persistent on startup without trip reset, indicates hardware failure); Blinking = Warning active |
Replacement and Spare Part Considerations
Replacing a Lenze EVS9323-EP requires confirming both electrical ratings and system interface hardware. The unit operates on 320 to 528 V AC mains and delivers 3.0 kW output power with a continuous rating of 7 A. When replacing an existing controller, the AIF fieldbus expansion module (such as PROFIBUS EMF2133IB or DeviceNet EMF2173IB) must be transferred from the original drive to the replacement unit to maintain fieldbus network compatibility.
A replacement drive must be loaded with the specific parameter set corresponding to the machine axis before operation. Because parameter profiles are stored in internal EEPROM memory, parameters can be transferred using a Keypad XT (EMZ9371BC) or uploaded and saved via Global Drive Control (GDC) software. Attempting to operate a replacement drive with factory default settings may cause axis positioning errors or drive trip conditions.
If the original drive exhibits internal hardware trips such as H05, OC1 with the motor disconnected, or persistent PEE errors, internal electronic component failure is present. In such cases, attempting field repairs on internal circuit boards is not recommended, and installing a fully tested replacement drive or seeking board-level repair service is required to restore system functionality.
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 on output terminals | Short circuit in motor cable, motor winding fault, ground fault, or damaged power stage | Check motor cable for damage, check motor insulation with megohmmeter.

Frequently Asked Questions
How do I transfer parameters from a failed Lenze EVS9323-EP to a replacement unit?
Parameters stored in the drive's internal EEPROM can be backed up using Lenze Global Drive Control (GDC) software via a CANbus or AIF connection, or saved directly into a Keypad XT (EMZ9371BC) operator module, which can then download the parameter set into the replacement drive.
What fieldbus communication modules can be used with the EVS9323-EP?
The EVS9323-EP includes an Automation Interface (AIF) slot that supports plug-in network modules, including PROFIBUS-DP (EMF2133IB), DeviceNet (EMF2173IB), and INTERBUS (EMF2111IB).
What does a solid red TRIP LED indicate on startup?
A solid red TRIP LED indicates an active fault trip condition. If the red light remains illuminated on startup after cycling power and cannot be reset, it points to an unrecoverable internal hardware fault.
What should be checked when fault code OC1 appears?
Fault code OC1 signifies a short circuit or ground fault. Check the motor power cabling and motor windings. If OC1 remains active even after disconnecting the motor leads, the drive's internal power stage is damaged and requires repair or replacement.
What is the power rating and output current of the Lenze EVS9323-EP?
The EVS9323-EP has a rated power output of 3.0 kW, a continuous output current of 7 A at an 8 kHz switching frequency, and a peak output current of 10.5 A for up to 60 seconds.
