Product Information
The Lenze 00450898 EVS9326-KHV531 is an 11 kW servo inverter belonging to the Lenze 9300 Servo family, engineered for precise speed and position control of synchronous and asynchronous servo motors. Operating on a 3-phase AC supply voltage between 320 V AC and 528 V AC (nominal 400 V AC to 480 V AC), this drive delivers a rated continuous output current of 24 A and a peak current capability of 36 A for up to 60 seconds. Designed with field-oriented vector control and an IP20 enclosure rating, the unit features a cold-plate thermal construction (KH designation) that transfers heat directly to external mounting surfaces, reducing cabinet enclosure depth and minimizing internal cooling airflow needs.
For inter-drive communication and system integration, the EVS9326-KHV531 incorporates a built-in CAN-based Lenze System Bus at terminal X4 along with a front Automation Interface (AIF) slot. This modular slot accepts option devices including the EMF2133IB PROFIBUS module, EMF2177IB System Bus Adapter, LECOM RS232/RS485 interfaces, INTERBUS modules, or the EMZ9371BC XT Keypad. Placing a replacement drive into service requires transferring the parameter dataset saved in internal EEPROM memory, which is executed using Global Drive Control (GDC) software or direct keypad backup restore. When transferring parameters or attempting parameter extraction from a faulty donor unit, technical support from ABC Industrial Parts can help ensure configured settings match the target axis requirements.
Diagnostic indication is provided on the drive panel via a green DRIVE READY status light and a red TRIP / FAULT status light, while detailed trip histories and fault records can be retrieved from parameter C0168 via GDC software or keypad. Initial troubleshooting steps should cover main line supply across L1, L2, and L3, motor thermistor connections at terminals T1/T2, feedback wiring at Sub-D terminal X7 and terminal X8, and proper 120-ohm termination on the CAN bus. When hardware fault codes such as EEr, EEr2, or H05 indicate internal control board or memory corruption, on-site board repairs are not practical; sourcing a tested exchange drive from ABC Industrial Parts offers a fast and effective way to restore production.

Programming and Configuration
The Lenze 00450898 EVS9326-KHV531 servo drive employs field-oriented vector control to run synchronous and asynchronous servo motors. Commissioning, diagnostic monitoring, and parameter adjustment are performed using Lenze Global Drive Control (GDC) software connected via a suitable communication interface or locally via the plug-in EMZ9371BC XT Keypad attached to the front Automation Interface (AIF) slot.
All operating parameters, feedback configurations, gain values, and fieldbus mappings are retained inside non-volatile internal EEPROM memory. When replacing an existing drive, the configured parameter set must be uploaded from the original unit or project file and downloaded into the replacement unit. If parameter corruptions or write errors occur during startup, reloading factory default settings or restoring a verified backup dataset resets the internal controller logic.
Communication and System Integration
System connectivity in the EVS9326-KHV531 is built around an integrated Lenze System Bus (CAN/CANopen) accessed through terminal connection X4. This bus interface allows fast inter-drive communication, parameter transfer, and multi-axis synchronisation without requiring extra communication cards. End nodes on the CAN system bus require 120-ohm termination resistors across the signal lines.
For higher-level network connectivity, the front Automation Interface (AIF) slot accommodates optional fieldbus communication modules, such as the EMF2133IB PROFIBUS-DP card, EMF2177IB System Bus Adapter, INTERBUS modules, or LECOM RS232/RS485 adapters. Motor feedback devices connect to dedicated hardware ports, including Sub-D connector X7 for resolvers, terminal X8 for incremental encoders, and terminals T1/T2 for motor temperature thermistor monitoring.
Diagnostics and Status Indication
Operational status and trip alerts are displayed on the front panel via LED indicators. Active fault conditions, warnings, and historic trip records are stored in parameter C0168, which can be read using Global Drive Control software or the EMZ9371BC keypad module. Diagnostic parameters also allow real-time checking of status words, motor phase currents, and internal DC bus voltage levels.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid / Flashing | Solid ON = Drive ready/enabled; Slow flashing (1 Hz) = Drive inhibited (CINH); Fast flashing (2 Hz) = Parameter transfer active. |
| TRIP / FAULT | Red - Solid / Flashing | Solid ON = Drive in TRIP fault condition; Flashing = Warning active or error code pending. |
Replacement and Spare Part Considerations
When replacing an existing Lenze 00450898 EVS9326-KHV531 drive, verifying the exact part number and model variant is critical. The "KH" suffix denotes the cold-plate heat sink construction, which relies on direct contact with an external cooling interface. Before mounting the spare unit, the cold-plate interface surface must be thoroughly cleaned and thermal compound applied to prevent overtemperature trips (OH).
In addition to mechanical mounting, all configuration parameters must be transferred from the original drive to the replacement using Global Drive Control software or the EMZ9371BC keypad. Optional fieldbus modules inserted into the front AIF slot, such as the EMF2133IB PROFIBUS module, must be transferred to the replacement unit and checked for proper mechanical seating.
