Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13015897 (model EVS9327-ES) is an 11 kW standard servo drive from the Lenze 9300 Series, engineered for dynamic speed and position control in automated industrial machinery. Operating across a 3-phase AC input voltage range of 320 V to 528 V AC, this IP20 cabinet-mounted unit delivers a rated continuous output current of 23.5 A with a peak current rating of 35.3 A. Utilizing Field Oriented Control (FOC) technology at an 8 kHz default switching frequency, the drive controls both AC synchronous servo motors and AC asynchronous induction motors across demanding applications such as packaging machinery, textile manufacturing, material handling systems, and web converting.
Interfacing the EVS9327-ES within a control system is supported by dedicated feedback interfaces and modular communication options. Speed and position feedback are handled via Sub-D connectors compatible with standard 2-pole or multi-pole resolvers, TTL incremental encoders, and SinCos encoders. Control signal wiring connects through 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. Commissioning a spare drive requires restoring application parameters, as the internal non-volatile EEPROM stores up to four parameter sets. Parameters can be managed using Lenze Global Drive Control (GDC) or EASY Starter software, or duplicated on site using the pluggable EMZ9371BC keypad operating module without needing a computer. Where parameter extraction from a unit or donor module is needed, ABC Industrial Parts provides support for verifying and preparing replacement drives.
Diagnostic state is indicated directly on the drive by a dual Red/Green status LED. A solid green LED signals drive ready and enabled status, while a blinking green LED indicates an enabled drive that is blocked or has reached its target speed. Active warnings and TRIP faults trigger blinking or solid red indications, respectively. Diagnostic evaluation is extended via parameter C0168, which logs the last 8 fault messages accessible through the EMZ9371BC keypad or GDC software, or via the hardware trip alarm relay contacts K11/K14. Fault codes range from OC1 output short circuits to OH heatsink overtemperature and OU DC bus overvoltage. Internal errors such as code H05 indicate internal hardware failure that is not field-serviceable, where unit repair or a tested exchange drive from ABC Industrial Parts offers a fast path back to production.

Programming and Configuration
Configuration and parameter setup for the Lenze 13015897 EVS9327-ES servo drive are performed using dedicated Lenze engineering software, including Global Drive Control (GDC) and EASY Starter. These software packages enable online drive monitoring, parameter modification, diagnostic readout, and drive commissioning across connected serial or fieldbus interfaces.
The drive contains internal non-volatile EEPROM memory capable of holding up to four complete parameter sets onboard. When replacing an existing drive, parameter data can be transferred directly without a PC using the pluggable EMZ9371BC keypad operating module. This module allows direct parameter duplication between drives, minimizing replacement downtime during field service.
Communication and System Integration
The Lenze 13015897 EVS9327-ES features an integrated CANopen system bus interface connected directly via control terminals. This onboard interface facilitates direct drive-to-drive networking for multi-axis synchronization and rapid data exchange across complex motion control architecture.
Network integration with higher-level PLCs is provided via a pluggable Automation Interface (AIF) slot. This modular expansion slot supports communication modules such as the EMF2131IB PROFIBUS module, INTERBUS modules, and RS-232/RS-485 serial communication cards, allowing integration into standard industrial fieldbus networks.
Diagnostics and Status Indication
Drive operating status is visually presented by a dual Red/Green LED indicator. A continuous green illumination indicates that the drive is ready for operation and enabled, whereas a blinking green light signals that the drive is enabled but blocked or target speed has been reached. A blinking red LED signifies an active warning, and a solid red LED indicates an active TRIP fault condition.
System fault history is maintained in parameter C0168, which tracks the last 8 fault messages. This error log can be examined on site using the EMZ9371BC keypad display or remotely via the GDC software online diagnostic window. A dedicated hardware relay output (K11/K14) also provides trip alarm signaling to external control systems.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Fault (Red/Green LED) | Red/Green - Solid, Flashing, or Off | Green glowing = Drive ready for operation / enabled; Green blinking = Drive enabled but blocked or target speed reached; Red blinking = Warning active; Red glowing = TRIP fault active. |
Replacement and Spare Part Considerations
Before installing a replacement Lenze 13015897 EVS9327-ES drive, verify that the unit power rating (11 kW), continuous current output (23.5 A), and input supply specification (3-phase 320 to 528 V AC) align with your machine requirements. Ensure cabinet ventilation meets specifications for an IP20 rated unit.
A replacement drive must be commissioned with the correct application parameter set prior to operation. Transfer the parameter profile from the faulty unit using either Global Drive Control (GDC) software or the EMZ9371BC keypad module. Additionally, move any optional plug-in fieldbus modules (such as the EMF2131IB PROFIBUS module) from the old unit's AIF slot to the replacement drive and verify bus addresses.
