Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13015968 EVS9323-EPV004 is a 1.5 kW servo drive from the 9300 Servo series, designed to perform precise closed-loop motor control and integrated positioning functions in automated production machinery. Operating across a 3-phase supply voltage range of 320 V AC to 528 V AC at 400 V nominal output, this controller delivers a continuous output current of 3.9 A with a peak overload capacity of 5.9 A for up to 60 seconds. Combining field-oriented vector control with onboard motion logic, the drive manages complex multi-axis motion, rotary indexing, and pick-and-place tasks without requiring execution overhead on the central PLC.
For system integration, the EVS9323-EPV004 features an onboard Lenze System Bus (CAN) running at up to 500 kbps alongside a multi-pin Automation Interface (AIF) slot for optional fieldbus communication modules, such as PROFIBUS-DP, DeviceNet, or CANopen. Motor feedback is routed through standard Sub-D interfaces supporting resolvers and TTL incremental encoders, complemented by 8 digital inputs, 4 digital outputs, and differential analog I/O. Commissioning a replacement unit requires restoring parameter sets to the replacement drive, which is handled either via the non-volatile EEPROM storage using a Lenze Keypad XT module or through Lenze Global Drive Control (GDC) software over the CAN bus. ABC Industrial Parts can support maintenance teams with replacement drives prepared to streamline system restoration.
Operational status and troubleshooting are facilitated by front panel status LEDs: a solid red TRIP LED signals an active fault and output stage disable, a green READY LED indicates readiness or active control, and a yellow IMP LED indicates pulse inhibition. Detailed diagnostic menus and active fault logs can be accessed via Keypad XT or GDC software, detailing conditions such as overcurrent (OC1, OC2), DC bus overvoltage (OU), or CAN bus communication faults (CE0). Basic checks should focus on line power, terminal wiring, 120-ohm CAN termination resistors, and cooling airflow. When internal controller faults like H05 or H10 occur, internal hardware components are not field-serviceable, making a replacement drive from ABC Industrial Parts the most reliable solution to resume production.

Programming and Configuration
Parameterization and motion profile configuration for the Lenze EVS9323-EPV004 are performed using Lenze Global Drive Control (GDC) software or locally via the pluggable Keypad XT module (EMF2133IB). The drive stores operational parameters and positioning profiles in internal non-volatile EEPROM memory, protecting configuration data against power loss.
When commissioning a replacement drive or transferring settings between units, parameter sets can be copied directly using the transfer feature of the Keypad XT module or downloaded from a saved GDC project file over the system bus. Ensuring matching parameter structures and alignment with installed option modules guarantees proper axis behavior upon startup.
Communication and System Integration
The EVS9323-EPV004 includes an integrated Lenze System Bus (CAN) interface capable of transmission speeds up to 500 kbps. This bus enables direct inter-drive communication and multi-axis synchronization across positioning applications without overloading main control networks.
For higher-level industrial network connectivity, the unit features a modular Automation Interface (AIF) slot. This interface supports optional communication cassettes, such as the EMF2133IB or EMF2131IB PROFIBUS-DP modules, as well as DeviceNet, INTERBUS, and CANopen adapters, providing flexible integration into existing PLC architectures.
Diagnostics and Status Indication
Diagnostics for the Lenze 13015968 EVS9323-EPV004 are supported by hardware LED indicators and detailed software diagnostics. The drive displays main status states through its front LEDs and maintains an internal error history log accessible through the Keypad XT diagnostic menu or online via Global Drive Control software.
Continuous monitoring of system registers over the Lenze System Bus provides real-time visibility into operational parameters, speed feedback, thermal states, and bus communications, allowing technicians to identify line faults and operating anomalies rapidly.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid | Fault active / Drive trip triggered. Output stage disabled. |
| Green LED (READY) | Green - Solid / Flashing | Drive operational status. Flashing = controller inhibit / ready; Solid ON = controller enabled / operating. |
| Yellow LED (IMP) | Yellow - Solid | Pulse inhibit active / warning state. |
Replacement and Spare Part Considerations
Replacing an EVS9323-EPV004 requires verifying that the replacement unit matches the 1.5 kW power rating and 320-528 V AC voltage range of the original drive. Fieldbus cassettes mounted in the AIF slot must be transferred to the replacement unit or matched in configuration to maintain network connectivity.
Because the drive relies on application-specific positioning profile parameters and motor tuning values, commissioning a spare requires backing up parameters from the existing drive and loading them into the replacement via EEPROM transfer or GDC software. For long-term facility planning, Lenze i700 and 9400 HighLine drive series offer a potential migration path for system upgrades.
