Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9326-ES (part number 13015896) is an 11 kW panel-mounted digital servo controller from the Lenze 9300 series, designed for demanding motion control tasks. Operating on a 3-phase supply voltage ranging from 320 V AC to 528 V AC at 45 to 65 Hz, this drive provides a continuous output current of 23.5 A at an 8 kHz switching frequency and an output frequency range of 0 to 480 Hz. Engineered for precise motor control in dynamic automation systems, the controller features 4 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs to handle complex machine sequence logic and speed or position references.
Interfacing the controller into existing systems is supported through an onboard Lenze CAN System Bus operating up to 500 kbit/s and dedicated feedback connectors for standard 2-pole resolvers or TTL incremental encoders with master frequency loop-through capability. Additional network capabilities are enabled via the integrated Automation Interface (AIF) slot, which accepts plug-in modules for PROFIBUS-DP, DeviceNet, CANopen, or INTERBUS, as well as the XT EMZ9371BC keypad. Commissioning and setup rely on Lenze Global Drive Control (GDC) software V4.x / V5.x or Easy Starter tools. When installing a replacement unit, parameter sets must be transferred to ensure exact operational matching, as up to four switchable parameter sets are stored in the controller's onboard non-volatile EEPROM memory. Technical specialists at ABC Industrial Parts can support parameter backup, configuration transfers, and verification when preparing a replacement drive for service.
Diagnostic conditions are communicated through three front-panel LEDs—Green for operational status, Yellow for warnings or impulse inhibits, and Red for active TRIP faults. Detailed operating status and a comprehensive fault history are stored in parameter code C0168. First-line troubleshooting involves inspecting mains power quality, CAN bus connections, feedback wiring, and thermal conditions. While external issues such as motor overtemperature or line undervoltage can be rectified in the field, codes indicating internal memory corruption, gate driver failure, or power stage errors signify board-level component failure. Because internal hardware faults are not field-serviceable, opting for a tested replacement unit or repair through ABC Industrial Parts provides a fast route to minimizing machine downtime.

Programming and Configuration
Configuration and parameterization of the Lenze EVS9326-ES servo controller are managed primarily through Lenze Global Drive Control (GDC) Software V4.x / V5.x or Easy Starter commissioning software. The controller stores up to four complete, switchable parameter sets in non-volatile onboard EEPROM memory. Stored parameter sets define operational limits, motor parameters, dynamic gain settings, and application-specific functions without losing data during power loss.
In addition to software-based engineering tools, local parameter editing and manual override are available using the plug-in Lenze XT EMZ9371BC operating keypad module fitted into the Automation Interface slot. During commissioning or parameter restoration, parameter settings stored in code registers—such as speed limit threshold C0596 and diagnostic log C0168—can be audited or reloaded to factory defaults when resolving memory corruption issues.
Communication and System Integration
The Lenze EVS9326-ES includes an onboard Lenze System Bus (CAN) interface capable of transmission speeds up to 500 kbit/s for high-speed peer-to-peer data exchange between multiple drives in synchronized motion control systems. Motor position and speed feedback are handled via integrated feedback interfaces, supporting standard 2-pole resolvers as well as TTL incremental encoders featuring master frequency loop-through output for multi-axis tracking.
For integration into higher-level industrial network architectures, the unit features a proprietary Automation Interface (AIF) slot. This modular expansion slot accommodates optional fieldbus communication modules, including the EMF2102IB PROFIBUS module, as well as modules for INTERBUS, DeviceNet, and CANopen. Proper installation requires verifying module seating, line termination, and fieldbus node addressing.
Diagnostics and Status Indication
System status monitoring on the EVS9326-ES is facilitated by front-panel LED indicators and diagnostic software registers. Three distinct LEDs provide real-time operating state visibility: the Green LED indicates operational state and controller enable status, the Yellow LED highlights warnings or impulse inhibit activation, and the Red LED alerts operators to TRIP conditions or internal hardware faults.
Detailed fault diagnostics are retrieved via parameter code C0168, which logs historic fault events and internal error states. When a fault occurs, the drive activates its dedicated TRIP relay output to signal the master machine controller. Troubleshooters should evaluate field wiring, power input, feedback cables, and fieldbus status before determining if hardware service is required.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green | Green - Solid / Flashing | Drive operational status and controller enable indication |
| Red | Red - Solid / Flashing | TRIP fault or hardware fault active |
| Yellow | Yellow - Solid / Flashing | Warning status or impulse inhibit active |
Replacement and Spare Part Considerations
Although the Lenze 9300 Servo series is officially discontinued, the EVS9326-ES (part number 13015896) remains an active replacement component across legacy automated production lines. When replacing an existing unit, technicians should verify part number equivalence across known cross-references, including 00405230 and EVS9326-ESV000, to guarantee identical physical mounting and electrical power ratings of 11 kW with a continuous 23.5 A output.
A replacement EVS9326-ES is not a plug-and-play device out of the box. Before placing a spare unit into operation, the application-specific parameter set must be uploaded from the original drive or restored from a software backup created via Lenze Global Drive Control. Ensuring that motor parameters, fieldbus addresses, terminal configurations, and operating modes match the original installation prevents dynamic axis mismatch or communication timeouts upon power-up.

Frequently Asked Questions
What engineering software is required to configure the Lenze EVS9326-ES servo controller?
Configuration and parameterization are performed using Lenze Global Drive Control (GDC) Software V4.x / V5.x or Lenze Easy Starter tools. Parameter adjustments can also be made locally using the optional XT EMZ9371BC operating keypad module.
What alternate part numbers cross-reference to the Lenze 13015896 servo drive?
The Lenze EVS9326-ES (part number 13015896) is cross-referenced under numbers 00405230 and EVS9326-ESV000. All share the same 11 kW power rating and 9300 series hardware architecture.
Can a replacement Lenze EVS9326-ES be installed without pre-configuration?
No, a replacement drive requires configuration prior to running the machine. Up to four parameter sets stored in non-volatile EEPROM must be transferred from the original controller or restored from a GDC software backup to match motor settings, control modes, and fieldbus parameters.
What fieldbus communication options are supported by the EVS9326-ES?
The drive includes an onboard CAN System Bus operating up to 500 kbit/s. For other fieldbus networks, the modular Automation Interface (AIF) slot supports optional plug-in modules for PROFIBUS-DP (such as the EMF2102IB), DeviceNet, CANopen, and INTERBUS.
What do the front-panel status LEDs indicate on the EVS9326-ES controller?
The Green LED indicates drive operation and controller enable state; the Yellow LED signals active warnings or impulse inhibits; and the Red LED indicates active TRIP conditions or internal hardware faults.
How should hardware error codes such as EER, H05, or PU be handled during troubleshooting?
Codes like EER (EEPROM fault), H05 (internal hardware error), and PU (power unit defect) indicate board-level or power component failures that cannot be repaired in the field. These errors require factory repair or replacing the controller with a tested exchange unit.
