Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVS9328-EP (part number 13180721) is a 22 kW servo positioning controller within the Lenze 9300 Servo Drives family. Engineered for multi-axis synchronized positioning, electronic gearing, and high-dynamic automated machinery, this unit combines power amplification, drive logic, and profile control in a single cabinet-mounted enclosure. It operates across a 3-phase supply voltage range of 320 V to 528 V AC at 45 to 65 Hz, supplying a continuous output current of 47 A and a peak short-term output current of 70.5 A with a maximum output frequency of 480 Hz.
Physical interfaces on the drive include an onboard CAN system bus operating at speeds up to 500 kbit/s, along with 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. Dedicated feedback interfaces accommodate resolvers on connector X7, SinCos encoders on connector X8, TTL incremental encoders, and Hiperface absolute sensors. An integrated Automation Interface (AIF) expansion slot allows connection to higher-level fieldbus networks using modules such as PROFIBUS-DP (EMF2133IB) or CANopen (EMF2178IB). Commissioning a spare unit requires parameter configuration rather than a direct plug-and-play installation, as machine profiles and node addresses stored in internal EEPROM parameter sets must be transferred. Parameter files can be cloned using the pluggable Keypad XT (EMF2102IB) display or uploaded via Global Drive Control (GDC) software with the EMF2177IB PC System Bus Adapter. Technical guidance from ABC Industrial Parts can assist during configuration transfer or fieldbus option alignment.
Operational status and fault conditions are displayed via front-panel Red, Green, and Yellow LEDs, while detailed fault logs are retained in internal drive parameters C0161 through C0168. First-line troubleshooting for suspected drive faults includes inspecting input line voltage phases, verifying feedback cable shielding at terminals X7 and X8, checking 120 Ohm CAN termination resistors, and ensuring cabinet cooling fans are operational. When internal system self-tests fail or internal memory errors occur, control board-level faults cannot be serviced in the field. Replacing the faulty module or sourcing a tested exchange controller through ABC Industrial Parts offers a fast path to restoring machine productivity.

Programming and Configuration
Engineering and software configuration for the Lenze EVS9328-EP is performed using Global Drive Control (GDC) software. Establishing a communication link between a PC and the controller requires a PC System Bus Adapter EMF2177IB. Through GDC, technicians can tune control loops, program multi-block positioning profiles, adjust switching frequencies, and monitor drive variables in real time.
For field parameter transfers without a PC, the drive supports the pluggable Keypad XT (EMF2102IB) display module. The controller includes non-volatile internal EEPROM storage holding up to four distinct parameter sets. These parameter sets permit complete drive configuration backups, allowing stored profiles, encoder setups, and CAN node settings to be copied directly from a donor unit into a replacement unit.
Communication and System Integration
Multi-axis motion coordination on the Lenze EVS9328-EP is handled via an onboard CAN system bus operating at speeds up to 500 kbit/s. This system bus provides high-speed drive-to-drive communication, enabling synchronized positioning, roll feed control, and master frequency repetition across complex machine setups without demanding heavy external wiring.
Integration with centralized factory automation networks is achieved using the Automation Interface (AIF) expansion slot. This slot accommodates optional communication modules including the PROFIBUS-DP module EMF2133IB and the CANopen module EMF2178IB. In addition to fieldbus cards, local machine control signals connect through onboard I/O comprising 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs.
Diagnostics and Status Indication
The EVS9328-EP provides real-time operational feedback through three front-mounted LED indicators and internal diagnostic parameters C0161 through C0168, which record recent TRIP events. System diagnostics, active warnings, and status words can be queried over CAN or fieldbus networks, displayed on the Keypad XT (EMF2102IB), or examined within the diagnostic tab of Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid / Flashing | TRIP active / Fault present. Drive disabled due to fault condition. |
| Green LED | Green - Solid / Flashing | Operation / Ready. Flashing = controller enable missing or drive standard operation ready; Steady ON = controller enabled and running. |
| Yellow LED | Yellow - Solid | Warning / Inhibit (IMP). Active power stage lock / current limit reached or warning state. |
Replacement and Spare Part Considerations
When swapping a damaged Lenze EVS9328-EP with a replacement unit, verifying configuration matching is critical. A spare drive will not run the machine until parameter profiles, feedback settings, and node addresses are written to its internal memory. Parameter files should be extracted from the existing drive or backup records and transferred via Global Drive Control software (using the EMF2177IB adapter) or copied directly using the Keypad XT (EMF2102IB) module.
Inspect the hardware configuration on the existing unit prior to installation. If the installation uses fieldbus control such as PROFIBUS-DP or CANopen, ensure the corresponding expansion card (e.g., EMF2133IB or EMF2178IB) is removed from the old unit and properly seated in the AIF slot of the replacement drive. Additionally, verify feedback connections at connectors X7 and X8, ensuring encoder cable shielding is grounded to prevent signal distortion.

Frequently Asked Questions
What software is used to configure and program the Lenze EVS9328-EP?
The Lenze EVS9328-EP is configured using Global Drive Control (GDC) software. A PC connects to the controller via the PC System Bus Adapter EMF2177IB to upload, download, and tune parameters.
Can I transfer parameters to a replacement EVS9328-EP without a PC?
Yes. Parameter sets can be copied and transferred using the pluggable Keypad XT (EMF2102IB) display module. Up to four parameter sets can be saved in non-volatile internal EEPROM memory and loaded into a spare unit.
What fieldbus communication options are supported on the EVS9328-EP?
The unit features an integrated CAN system bus operating at up to 500 kbit/s. For additional protocols, the Automation Interface (AIF) slot accepts option cards such as the PROFIBUS-DP module (EMF2133IB) and the CANopen module (EMF2178IB).
What causes an OH heatsink fault on the Lenze EVS9328-EP?
An OH fault indicates that the heatsink temperature has exceeded 90 °C. Common causes include a defective cooling fan, clogged heatsink fins, insufficient panel ventilation, or prolonged motor overload.
How should an H05 or EE fault code be handled?
An EE code indicates an EEPROM memory checksum error, while H05 indicates an internal hardware self-test failure. If reloading factory settings does not clear the fault, these represent internal board-level failures that require controller replacement or unit repair.
