Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00451419 EVF8245-E is an 11 kW frequency inverter from the Lenze 8200 series, engineered for precise 3-phase motor speed regulation in industrial environments. Designed to operate across a broad supply voltage range of 320 V AC to 528 V AC, this AC drive delivers a rated output current of 23.5 A with a peak output current capacity of 35.3 A, supporting 150% overload demands for up to 60 seconds. Operating across an output frequency range of 0 Hz to 480 Hz with adjustable switching frequencies from 2 kHz to 16 kHz, the unit features dual control capability, allowing configuration for standard V/f characteristic curve control or vector control for high-torque low-speed performance. It drives variable speed operations in conveyor transport systems, centrifugal pumps, industrial fans, and agitator machinery across material handling, packaging, water, and chemical processing facilities.
Integrating the EVF8245-E into an existing cabinet involves connecting fieldbus interfaces and transferring operational parameters. The drive architecture includes an open plug-in function slot designed to host communication adapters such as the EMF2102IB LECOM module, the EMF2171IB CANopen system bus module, or the EMF2133IB PROFIBUS-DP module. Placing a spare unit into service requires copying the four non-volatile parameter sets stored in internal EEPROM, which can be accomplished using the optional EMZ8201BB keypad module or Lenze Global Drive Control (GDC) PC software. Swapping the fieldbus module and loading saved parameters onto the spare unit ensures proper network addressing and matching motor profiles. ABC Industrial Parts can assist maintenance teams with technical guidance when transferring parameter profiles or preparing donor units for installation.
System status monitoring and troubleshooting on the EVF8245-E rely on integrated visual indicators and software diagnostic tools. Two front-panel LEDs provide immediate state indication: a green LED displays inverter operation readiness, while a red LED signals an active TRIP condition or fault state. Detailed error history and diagnostic codes—such as overcurrent events (OC1, OC2, OC3, OC5), DC bus overvoltage or undervoltage (OU, LU), and thermal overload warnings (OH, OH7)—are displayed via the EMZ8201BB keypad or monitored online using GDC software. Initial troubleshooting should confirm line voltage supply stability, check motor winding insulation, inspect cooling fan operation, and verify fieldbus module alignment. Unrecoverable memory errors, such as internal EEPROM faults (EER), indicate hardware failures that are not field-repairable, making unit exchange or repair through ABC Industrial Parts the standard route to restore operational production.

Programming and Configuration
The Lenze EVF8245-E frequency inverter uses non-volatile EEPROM memory to store up to four distinct internal parameter sets. These parameter profiles enable flexible multi-mode machinery control without requiring external reprograming during production line changeovers.
Parameterization and drive tuning are executed using Lenze Global Drive Control (GDC) PC software or directly through the optional plug-in EMZ8201BB keypad module. During unit replacement, saved configuration files or keypad parameter clones can be downloaded directly into the replacement drive to match existing acceleration profiles, current limits, and operational parameters.
Communication and System Integration
Network integration for the 00451419 drive is supported via an open function module option slot. The modular interface design accepts various fieldbus cards to connect the inverter directly into plant control networks.
Supported communication cards include the EMF2102IB LECOM module (RS232/RS485), the EMF2171IB CANopen system bus module, and the EMF2133IB PROFIBUS-DP module. Installing these options enables continuous speed command transmission, remote control, and online drive diagnostics from a central PLC.
Diagnostics and Status Indication
Front-panel visual indicators provide immediate status monitoring for the EVF8245-E inverter. A green status LED indicates operational readiness and inverter state, while a red LED illuminates or flashes to indicate an active TRIP fault condition.
Comprehensive diagnostic logging and active operating values are accessible using the EMZ8201BB keypad display or via the online diagnostic monitor in Lenze Global Drive Control (GDC) PC software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Solid / Flashing | Inverter state / Operation ready indication |
| Red LED | Red - Solid / Flashing | Fault condition / TRIP active indication |
Replacement and Spare Part Considerations
When swapping out a defective EVF8245-E frequency inverter, ensure that installed communication option cards—such as the EMF2102IB LECOM, EMF2171IB CANopen, or EMF2133IB PROFIBUS-DP module—are physically transferred to the replacement unit. The keypad module EMZ8201BB must also be reattached if keypad control or parameter cloning is utilized.
Because operational settings reside in non-volatile EEPROM memory across four distinct parameter sets, backup parameter files should be loaded into the donor unit via Global Drive Control (GDC) software or keypad copy functions before running the system. For complete machine redesigns or plant modernization projects, Lenze recommends migrating to the modern i550 cabinet frequency inverter series.
