Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13252010 EVS9328-ES is a 22 kW AC servo drive from the 9300 Servo Drives family, engineered for precise closed-loop speed, torque, and position control. Operating from a three-phase supply voltage ranging from 320 to 528 V AC at 45 to 65 Hz, the unit provides a continuous output current of 47 A at 400 V AC with a maximum output frequency of 480 Hz. To handle dynamic loads during acceleration, the inverter features a 150% overload capacity that delivers up to 70.5 A for up to 60 seconds. Designed for vertical panel mounting inside IP20 control cabinets, the drive incorporates dedicated resolver feedback processing to support AC brushless servo motors in multi-axis automation lines.
Connecting the drive into an existing control system involves both physical I/O terminals and dedicated communication interfaces. The EVS9328-ES features four digital inputs, two digital outputs, two analog inputs, two analog outputs, and a simulated encoder frequency output used for electronic gearing and line-shafting applications. System-level integration is supported via an onboard CAN system bus interface and an expansion slot (Slot A) compatible with modular fieldbus cards, including PROFIBUS-DP (EMF2133IB), CANopen (EMF2175IB), Interbus (EMF2102IBC), and LECOM RS-232/RS-485 (EMF2102IBV). Putting a replacement drive into service requires parameter alignment, as up to four switchable parameter sets are stored in the internal EEPROM. Transferring parameter data requires either the optional Keypad XT (EMF2102IB) or Lenze Global Drive Control (GDC) software version 4.0 or higher. Technical support from ABC Industrial Parts can assist in verifying setup parameters and recovering stored configurations from original units.
Diagnostic conditions are indicated directly through three status LEDs on the unit faceplate. A solid green RUN LED confirms normal operation with the inverter output stage enabled, a solid yellow WARN LED signals that a warning threshold such as an overload limit has been reached while keeping the output active, and a solid red TRIP LED indicates an active drive fault that disables the output stage. Detailed diagnostic data can be accessed via parameter C0168 (history buffer), status word C0150, or through textual error messages on the Keypad XT and GDC software oscilloscope logs. When troubleshooting fault conditions, initial checks should focus on mains supply stability, resolver cabling at terminal X3, motor winding continuity, and fieldbus module seating in Slot A. Internal errors like EEPROM corruptions or hardware self-test failures represent board-level defects that cannot be serviced in the field, making unit replacement or repair through ABC Industrial Parts the most direct path to restoring machine production.

Programming and Configuration
Parameterization of the Lenze 13252010 EVS9328-ES servo drive is managed through Lenze Global Drive Control (GDC) PC software version 4.0 or higher, or using the pluggable Keypad XT (EMF2102IB) module. The internal EEPROM memory maintains up to four independent parameter sets, allowing operators to switch between different machine operating profiles or motor configurations.
Commissioning a replacement inverter requires uploading the existing parameter configuration from the original unit or backup file. Using GDC software or copying parameters via the Keypad XT ensures that motor data, switching frequencies (defaulting at 8 kHz), velocity loops, and I/O assignments match system requirements. Direct parameter extraction from non-responsive boards can preserve operational settings prior to swapping hardware.
Communication and System Integration
The EVS9328-ES incorporates an integrated CAN-based system bus interface designed for multi-axis drive synchronization, master-slave operations, and direct inter-drive communication without dedicated PLC hardware. For integration into broader industrial networks, the unit contains a dedicated modular card slot (Slot A).
Option modules compatible with Slot A include PROFIBUS-DP (EMF2133IB), CANopen (EMF2175IB), Interbus (EMF2102IBC), and LECOM RS-232/RS-485 (EMF2102IBV). Additional control hardware interfaces include four digital inputs, two digital outputs, two analog inputs, two analog outputs, and a simulated encoder output for precise electronic gearbox configuration.
Diagnostics and Status Indication
Visual diagnostic feedback on the EVS9328-ES is provided through three front-panel LEDs. The green RUN LED illuminates when power is applied and the output stage is enabled. The yellow WARN LED alerts technicians to impending fault conditions, such as current limit or thermal warning thresholds, while allowing continued operation. The red TRIP LED indicates a critical fault that immediately disables drive output.
Comprehensive diagnostic evaluation is supported through system parameter C0168, which logs historic fault codes, and parameter C0150, which provides real-time status word feedback over CANbus or fieldbus networks. Advanced diagnostics, including real-time signal logging and trend analysis, are available via the oscilloscope function in Global Drive Control software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP) | Red - Solid | Indicates active drive fault/trip condition. Output stage is disabled. |
| Green LED (RUN) | Green - Solid | Indicates drive is powered and operating normally; output stage enabled. |
| Yellow LED (WARN) | Yellow - Solid | Indicates drive warning limit reached (e.g. current limit, Ixt warning). Output stage remains active. |
Replacement and Spare Part Considerations
When replacing an existing Lenze EVS9328-ES (part number 13252010), verify that the mechanical mounting space and IP20 vertical enclosure dimensions match the control cabinet layout. The drive requires a 320 to 528 V AC three-phase supply and supplies 47 A continuous output current to 400 V AC servo motors.
Before powering up a replacement drive, transfer any existing fieldbus communication modules from Slot A (such as PROFIBUS-DP or CANopen) to the spare unit. Ensure that parameter sets are fully restored using a Keypad XT or GDC software, confirming that CANbus node addresses, terminal I/O assignments, and resolver settings match the machine's control program.
