Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00400052 EVF8245-E is a 15 kW AC frequency inverter from the 8200 vector series, engineered for precise variable speed and torque motor control in industrial automated machinery. Built for panel and control cabinet installation with an IP20 protection rating and integrated heatsink, this drive operates on a 3-phase AC supply ranging from 320 V to 528 V AC (400 V / 480 V AC nominal) with a rated mains input current of 38 A. The drive provides a continuous output current rating of 32 A across an output frequency range of 0 to 480 Hz with an 8 kHz switching frequency. Capable of handling demanding motion applications, it supports multiple control methods including sensorless vector control, V/f characteristic curve control, and direct torque control.
Integrating the EVF8245-E into an existing control system relies on plug-in Function Module slots (FIF), allowing custom physical interface and network configurations. The drive accommodates Standard I/O or Application I/O modules, as well as fieldbus interfaces such as PROFIBUS-DP (EMF2133IB) and CANopen (EMF2173IB / EMF2178IB). Commissioning a replacement unit requires restoring the machine's parameter profile, as a spare drive is not plug-and-run without parameter configuration. Parameters stored in up to 4 internal non-volatile parameter sets can be written and backed up using the Keypad XT (EMF2102IB) operating module or Lenze Global Drive Control (GDC) software. Expert technical assistance from ABC Industrial Parts can assist in parameter extraction and configuration backup transfer when replacing a failed drive.
Operating status and faults are visually indicated via front-panel LEDs, where a solid green LED indicates operational readiness, a blinking green LED signals operation inhibited, a solid red LED indicates an active trip or fault, and a blinking red LED denotes a warning. In-depth diagnostics are managed via parameter C0183 for active trip conditions and parameter C0161 for the fault history log, accessible via Keypad XT or GDC software. First-line troubleshooting for trip codes like overcurrent (OC1, OC2, OC5), overvoltage (OU), or undervoltage (LU) involves checking motor wiring, mains voltage stability, and deceleration ramp times. For internal control board failures or hardware faults such as H05 or system fault Pr1, internal components cannot be serviced on-site, making unit repair or a reconditioned replacement unit from ABC Industrial Parts the effective route to restore production.

Programming and Configuration
Programming and parameter management for the Lenze 00400052 EVF8245-E inverter are conducted using Lenze Global Drive Control (GDC) software or the plug-in Keypad XT module (EMF2102IB). The drive architecture incorporates internal EEPROM memory capable of holding up to 4 independent parameter sets. This multi-parameter structure allows operators to store alternative application profiles or maintain standard configuration sets directly within non-volatile onboard memory.
When commissioning a spare unit or adjusting machine parameters, software communication is established via the front interface. Parameter code C0002 allows technicians to reset the inverter to factory default settings when needed. In the event of parameter memory corruption indicated by fault code P12, reloading factory default settings and restoring stored parameter files via GDC software re-establishes valid drive operation.
Communication and System Integration
System integration for the EVF8245-E inverter is built around Lenze's flexible plug-in Function Module slots (FIF). The drive separates basic power electronics from interface functions, allowing maintenance teams to insert required digital, analog, or fieldbus modules directly into the front slot of the unit.
Compatible network interface options include the EMF2133IB PROFIBUS-DP module and the EMF2173IB or EMF2178IB CANopen modules, as well as modules for INTERBUS, DeviceNet, and AS-Interface. In addition to fieldbus automation modules, Standard I/O and Application I/O modules provide hardwired control terminals. If communication between the internal drive processor and an attached function module is interrupted, the inverter registers fault code CE0.
Diagnostics and Status Indication
The EVF8245-E inverter features comprehensive real-time monitoring and visual indicators on its front panel. Internal diagnostic routines continuously monitor DC bus voltage levels, output phase currents, heatsink temperatures, internal enclosure thermal thresholds, and motor I²t thermal overload calculations.
Detailed fault evaluation is supported by onboard diagnostic parameter codes. Parameter code C0183 displays current trip conditions, while parameter code C0161 maintains a fault history log. Diagnostic status and active alarms can be monitored live through the GDC software diagnostic panel or read directly from the Keypad XT display.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Solid / Blinking | On = Inverter ready / operation enabled; Blinking = Operation inhibited or controller disable active |
| Red LED | Red - Solid / Blinking | On = Active trip/fault present; Blinking = Active warning present |
Replacement and Spare Part Considerations
Replacing a failed 00400052 EVF8245-E frequency inverter requires matching both the main unit part number and the configuration of attached function modules. Ensure that the replacement drive matches the 15 kW power rating, 32 A output current capacity, and 320 V to 528 V AC input voltage range. Transfer the plug-in communication or I/O module from the original drive to maintain fieldbus connectivity.
A replacement unit will not operate correctly until the original machine's parameter profile is written to its internal memory. Parameter sets can be loaded directly using Lenze Global Drive Control software or transferred using the Keypad XT module. While the 8200 vector product line is discontinued, maintaining direct replacements allows plant operators to avoid immediate control redesigns. For complete system overhauls, the Lenze i550 cabinet frequency inverter series represents the official migration path.
