Product Information
The Lenze EVS9326-ES (part number 034927940173) is an 11 kW panel-mount servo drive belonging to the Lenze 9300 Servo product family. Operating on a 3-phase AC supply rating from 400 V to 480 V AC (with an acceptable operating range from 320 V to 528 V AC), this servo controller delivers a continuous output current of 23.5 A with a peak current capacity of 35.3 A for up to 60 seconds during dynamic acceleration cycles. Designed for precise speed, torque, and position control in packaging, material handling, textile, and paper converting machinery, the drive utilizes field-oriented vector control to drive both permanent magnet AC synchronous servo motors and AC asynchronous motors.
Interfacing and field integration are centered on an integrated CAN/CANopen system bus accessible via terminal strip X4, supporting baud rates up to 500 kbit/s, alongside a pluggable Automation Interface (AIF) slot. The AIF slot accepts optional communication modules, including the EMF2133IB PROFIBUS module, EMF2111IB INTERBUS module, or EMF2102IB LECOM RS-232/RS-485 interface. Built-in feedback connections include a Sub-D 9-pin input for 2-pole and multi-pole resolvers, an incremental encoder interface, and a frequency bus simulation output. Commissioning and parameter assignment are performed through Lenze Global Drive Control (GDC) software or the pluggable EMZ9371BC keypad operating module. When commissioning a replacement unit, parameter sets saved in one of the four internal non-volatile memory slots must be transferred from the donor controller, a process supported by technical services from ABC Industrial Parts.
System status and immediate diagnostic indications are displayed via two front-panel LEDs alongside text notifications on the optional EMZ9371BC keypad. A flashing green LED signifies drive enablement and active operation, while a steady green LED indicates control power is present with the drive inhibited. A flashing red LED highlights active warnings or TRIP conditions, and a steady red LED indicates a major internal fault. Detailed troubleshooting is facilitated by the fault history log stored in memory or real-time diagnostic monitoring in GDC software. First-line field checks should verify mains voltage stability, DC bus levels, cooling fan operation, and fieldbus termination. Internal power stage failures or hardware faults—such as trip codes EER or H05—cannot be serviced in the field, making unit replacement or repair through ABC Industrial Parts the effective route to restore production.

Programming and Configuration
The Lenze EVS9326-ES utilizes Lenze Global Drive Control (GDC) PC software for system configuration, parameter management, and motion profiling. Connected via an optional LECOM interface or system bus connection, GDC provides full visual parameter trees and diagnostic access to the controller.
The controller features non-volatile internal memory capable of storing up to four complete, independent parameter sets. Operators can manually adjust parameters or back up complete device profiles using the optional EMZ9371BC keypad operating module, enabling straightforward parameter duplication across identical drive axes.
Communication and System Integration
For multi-axis motion synchronization and central controller integration, the EVS9326-ES features an integrated CAN/CANopen system bus interface located at terminal strip X4. The CAN interface supports communication speeds up to 500 kbit/s and requires standard 120 Ohm termination resistors at both physical ends of the network segment.
Fieldbus extension is enabled via the front-panel Automation Interface (AIF) slot. This modular slot accommodates optional interface cards including the EMF2133IB for PROFIBUS-DP, the EMF2111IB for INTERBUS, and the EMF2102IB for LECOM RS-232/RS-485 serial communications.
Diagnostics and Status Indication
Status evaluation for the EVS9326-ES is provided through onboard LED indicators, the EMZ9371BC keypad display, and GDC software windows. The drive logs active TRIP events and warnings into an internal fault history parameter memory, maintaining diagnostic records across power cycles.
System diagnostics over the CAN bus allow upper-level automation controllers to monitor operating states, drive enable statuses, and active fault conditions in real time during machine operation.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready) | Green - Flashing / Solid / Off | Flashing = Drive enabled / normal operation; On steady = Drive powered and ready (inhibited); Off = No control supply voltage. |
| Red LED (Fault) | Red - Flashing / Solid | Flashing = Active warning or fault condition (TRIP); On steady = Major fault active or internal hardware failure. |
Replacement and Spare Part Considerations
When substituting an existing drive with a replacement Lenze EVS9326-ES, verify that power rating (11 kW) and hardware model numbers correspond directly. The replacement drive must be loaded with the existing parameter set stored from the original unit using GDC software or the EMZ9371BC keypad module.
Ensure that any installed Automation Interface (AIF) option module, such as a PROFIBUS or INTERBUS card, is transferred to the replacement drive prior to installation. Verify physical CAN bus termination resistors and node address settings on terminal strip X4 to ensure network communication is restored without interruption.
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 / Overcurrent | Instantaneous overcurrent detection in motor output phases. | Short circuit or ground fault in motor cable, motor winding fault, incorrect motor data, acceleration time set too fast. | Check motor and motor wiring for short circuits or ground faults. Inspect motor parameters. If code triggers instantly without motor cable attached, internal power stage failure is present requiring unit replacement/repair. |
| OC5 | I*t Inverter Overload | Continuous thermal overload of drive power section. | Drive operated above continuous output current limit for too long, mechanical binding in load. | Check mechanical load, reduce cycle duty or acceleration rate, verify drive sizing. |
| OU | Overvoltage DC Bus | DC bus voltage exceeded safe upper limit threshold (> 770 V DC). | Excessive regenerative energy during deceleration, deceleration ramp too short, missing or defective braking resistor / chopper. | Extend deceleration time, check braking resistor connection and value, check mains voltage level. |
| LU | Undervoltage DC Bus | DC link voltage fell below minimum allowable operating threshold (< 400 V DC). | Mains supply failure, voltage drop on grid, loose mains wiring, blown input line fuses. | Check input power supply voltage, inspect input fuses, check power contactors and supply connections. |
| OH | Heatsink Overtemperature | Inverter heatsink temperature exceeds limit (> 85 °C). | Cooling fan failed, clogged heatsink cooling fins, insufficient enclosure ventilation, excessive ambient temperature. | Clean heatsink, inspect internal/external cooling fans, verify cabinet ventilation flow. |
| OH4 | Motor Overtemperature | Motor temperature switch or PTC sensor triggered. | Motor thermal overload, cooling fan failure on motor, defective PTC sensor wiring. | Allow motor to cool down, inspect motor load and cooling, check PTC sensor wiring at terminal X6. |
| CE0 | System Bus Communication Fault | Communication failure or interruption on integrated CAN system bus. | Damaged CAN cable, incorrect baud rate, missing bus termination resistor, heavy interference. | Verify CAN bus wiring, check 120 Ohm termination resistors at both ends of network, check CAN baud rate settings. |
| Pr | Parameter Error | Parameter checksum fault or invalid data stored in parameter memory. | Power failure during parameter save, corrupted memory. | Reload parameter set or perform factory parameter reset (load default parameter set). |
