Lenze EVS9328-EP 13253370 – 9300 Servo Positioning Controller 22 kW
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9328-EP (part number 13253370) is a 22 kW servo positioning controller from the Lenze 9300 Servo product family, built for dynamic motion control applications such as positioning drives, electronic shaft synchronization, packaging machinery, and material handling systems. Operating on a 3-phase AC input supply spanning 320 V to 528 V, the drive delivers a continuous output current of 47 A with a rated input current of 43 A. Its output stage operates at an 8 kHz default switching frequency and supports a 150% peak current overload up to 70.5 A for dynamic acceleration phases, providing integrated positioning control directly within the drive hardware.
Engineered for flexible integration into automated machinery, the EVS9328-EP supports resolver feedback via connector X7 as well as TTL incremental, SinCos, EnDat, and SSI absolute encoders via connector X8. System networking is provided through an onboard CAN system bus operating at 500 kbit/s, while Slot X5 accepts optional fieldbus modules such as EMF2133IB, EMF2192IB, and EMF2102IB for PROFIBUS-DP, EtherCAT, DeviceNet, InterBus, and LECOM communications. Replacing an existing drive requires transferring machine parameters, as the internal non-volatile memory holds up to four independent parameter sets (PAR1 to PAR4). Commissioning and parameter transfer are executed using Lenze Global Drive Control (GDC) software or the plug-in EMZ9371BB keypad, and ABC Industrial Parts can assist in preparing pre-configured replacement units.
System status and operational readiness are indicated through onboard LEDs, including a red TRIP LED for active fault conditions, a green LED for drive operation or inhibit status, and a yellow warning LED. Diagnostic monitoring and parameter verification are available through the EMZ9371BB keypad display, CAN bus diagnostics, or the GDC software oscilloscope interface. Active faults such as DC bus overvoltage (OU), resolver loss (Sd2), or positioning lag errors (PI) point directly to external wiring, motor, or parameter issues that field technicians can verify on-site. Internal hardware failures such as H05 or sensor faults such as H10 indicate unserviceable internal board issues, where exchanging the unit through ABC Industrial Parts provides a fast route back to production.

Programming and Configuration
Configuration of the Lenze EVS9328-EP positioning controller is managed using Lenze Global Drive Control (GDC) engineering software or directly via the detachable EMZ9371BB keypad module. GDC provides tools to configure motion profiles, set electronic gearing ratios, calibrate feedback systems, and monitor internal drive signals in real time using an integrated oscilloscope utility.
The controller features internal non-volatile memory capable of storing up to four complete parameter sets (PAR1 through PAR4). This multi-dataset architecture allows machine builders and plant engineers to maintain alternative operational profiles directly within the drive. When replacing a failed controller, parameter set backups can be written into the replacement unit to ensure identical motion response without re-engineering the application.
Communication and System Integration
The EVS9328-EP includes an onboard CAN system bus interface operating at 500 kbit/s, enabling rapid cross-communication between multiple Lenze drives or higher-level PLCs. Physical control interface points include 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs for direct integration with control hardware.
For integration into major fieldbus networks, the controller is equipped with expansion Slot X5, which accepts option cards such as the EMF2133IB, EMF2192IB, and EMF2102IB. These plug-in cards enable communication over PROFIBUS-DP, EtherCAT, DeviceNet, InterBus, or LECOM serial interfaces. Feedback evaluation is handled through dedicated terminals, using connector X7 for resolvers and connector X8 for TTL incremental, SinCos, EnDat, and SSI absolute encoders.
Diagnostics and Status Indication
Visual diagnostics on the front face of the EVS9328-EP are provided by three dedicated status LEDs. A solid red TRIP LED signals an active fault condition with output inhibition; a solid or blinking green LED shows controller run or inhibit status; and a solid yellow LED indicates an active warning or IMP pulse inhibit state.
Detailed fault diagnostics are conducted using the EMZ9371BB keypad display, network registers over the CAN system bus, or the GDC software diagnostic window. The drive logs specific fault codes to isolate electrical, thermal, mechanical, or network anomalies during operation.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid | Fault condition active; controller inhibited / output turned off |
| Green LED (Ready) | Green - Solid / Blinking | Solid green = controller enabled/running; Blinking green = controller inhibit or ready |
| Yellow LED (Warning) | Yellow - Solid | Warning state / IMP pulse inhibit active |
Replacement and Spare Part Considerations
When selecting a spare unit for an existing machine, confirm that both part number 13253370 and model designation EVS9328-EP match the target drive. Because this 22 kW positioning controller relies on application-specific motor parameters and motion profiles, a replacement unit cannot operate until configured with the machine's parameter data.
Prior to commissioning a replacement unit, verify that any plug-in fieldbus module in Slot X5 (such as an EMF2133IB, EMF2192IB, or EMF2102IB card) is moved from the old drive to the spare unit. Reload parameter set PAR1 (along with PAR2 through PAR4 if used) using Lenze GDC software or the EMZ9371BB keypad module, and ensure feedback connections at terminals X7 or X8 match the physical transducer installed on the motor.
