Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV753K4B201 is a 7.5 kW frequency inverter from the 8200 Vector series designed for precise speed and torque regulation of three-phase AC industrial motors. Operating across a broad supply voltage range of 320 V AC to 528 V AC, this IP20-rated variable frequency drive delivers a rated output current of 16.5 A with a 150% heavy-duty overload capability reaching 24.8 A for up to 60 seconds. This specific variant (201) is built without an integrated radio frequency interference (RFI) filter, making it ideal for control cabinet installations that employ external line filters or centralized EMC suppression. The unit supports versatile motor control methods, including sensorless vector control alongside linear and quadratic V/f characteristic curves, with an output frequency range from 0 to 480 Hz.
Integrating a replacement drive into an operational machine requires matching physical communication modules and transferring the application parameter configuration. The 8200 Vector series features a modular architecture that accepts plug-in fieldbus options, such as the E82ZAFCC CANopen module, E82ZAFPC PROFIBUS-DP module, and E82ZAFAC RS485 LECOM module, as well as System Bus CAN and RS-232 interfaces. Commissioning a replacement unit is straightforward thanks to the detachable Electronic Programmable Module (EPM), a plug-in hardware memory chip that enables direct parameter cloning without connecting software. Drive setup can also be managed using the optional XT Keypad (E82ZBC) or Lenze Global Drive Control (GDC) PC software. ABC Industrial Parts can assist maintenance teams with parameter extraction from donor units and selecting matching replacement hardware.
Real-time diagnostic feedback is provided on the front panel by dual LED status indicators, where a green LED signals operational readiness and a red LED alerts operators to an active trip or fault condition. When accessed via the XT Keypad or GDC software, the drive reveals a comprehensive fault history buffer detailing trip events such as output overcurrent (OC1–OC4), DC bus overvoltage (OU) or undervoltage (LU), heatsink and motor thermal overload (OH, OH4, OH7, OH8), input phase failure (LP1), and parameter errors (InE, PEr). Practical first-line troubleshooting involves measuring line input voltages across all phases, verifying cooling airflow, and confirming EPM memory chip seating. Internal power stage or control board failures cannot be repaired on-site; acquiring a tested exchange unit or utilizing professional repair through ABC Industrial Parts provides a fast route to restoring production.

Programming and Configuration
Parameter management on the Lenze E82EV753K4B201 centers on the plug-in Electronic Programmable Module (EPM). The EPM chip functions as a removable hardware memory store for all drive parameters. Maintenance technicians can clone parameters offline or transfer an existing EPM chip directly from a failed unit into a replacement inverter, restoring complete drive functionality in seconds without requiring a programming cable or software connection.
For direct manual parameterization, the drive supports the plug-in Lenze XT Keypad (E82ZBC). Alternatively, advanced setup, real-time monitoring, and parameter archiving can be performed on a PC using Lenze Global Drive Control (GDC) software. If parameter corruption occurs or illegal parameter combinations are configured, a factory reset command can restore default settings before re-commissioning.
Communication and System Integration
The 8200 Vector architecture features a flexible interface slot for fieldbus integration. The E82EV753K4B201 accepts multiple interchangeable communication modules, allowing the inverter to fit seamlessly into diverse automation networks. Supported options include the E82ZAFCC CANopen module, E82ZAFPC PROFIBUS-DP module, and E82ZAFAC RS485 LECOM module, as well as System Bus CAN and RS-232 serial interfaces.
These plug-in modules enable the drive to accept remote start/stop commands, velocity setpoints, and torque limits while returning operational status and trip alarms to a central PLC. When replacing a drive in a networked system, transferring the communication module from the original drive ensures hardware interface compatibility and retains existing network address settings.
Diagnostics and Status Indication
Visual operational status is provided via two status LEDs on the front panel of the E82EV753K4B201. The green LED indicates power and operational readiness, flashing or remaining solid depending on the drive state. The red LED illuminates solid when a drive fault or trip condition occurs, indicating an active fault that requires inspection or a manual reset.
Detailed trip diagnostics are logged in an internal fault history buffer accessible using the optional XT Keypad or Global Drive Control (GDC) software. The buffer retains recent error codes, helping technicians trace specific electrical, thermal, or operational trips during fault analysis.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready) | Green - Solid / Blinking depending on state | Inverter operational, ready for operation / running status |
| Red LED (Fault) | Red - Solid | Drive fault or trip condition present; active fault requiring action or reset |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV753K4B201 drive, confirm the exact variant identifier. Suffix 201 signifies that the inverter is built without an internal RFI filter. If replacing a unit in a panel that relies on central line filtering, installing a drive variant with an integrated filter could alter panel leakage currents or grounding schemes.
Commissioning a spare drive requires moving both the plug-in communication option card and the EPM parameter memory module from the failed inverter to the replacement unit. Always verify that the EPM chip is fully seated in its front panel slot before powering on the drive. Although Lenze has phased out the legacy 8200 Vector family in favor of the modern i550 series, direct replacement units remain essential for maintaining established machinery without modifying control wiring or PLC programs.

Frequently Asked Questions
How do I transfer drive parameters to a replacement Lenze E82EV753K4B201?
Parameter transfer is accomplished by removing the plug-in EPM memory chip from the front panel of the original drive and inserting it directly into the replacement inverter. Drive parameters can also be loaded using Lenze Global Drive Control (GDC) software or programmed via the XT Keypad.
Does the E82EV753K4B201 variant include an internal RFI filter?
No, the 201 variant suffix indicates that this model is manufactured without an integrated RFI filter. It is intended for systems that utilize external line filters or central cabinet filtering.
Which fieldbus interfaces are compatible with this drive?
The 8200 Vector series accepts interchangeable plug-in communication modules including CANopen (E82ZAFCC), PROFIBUS-DP (E82ZAFPC), and RS485 LECOM (E82ZAFAC), alongside System Bus CAN and RS-232 interfaces.
What should I check if the drive indicates an InE fault code?
An InE fault code signifies an internal fault or EPM memory error. Verify that the EPM memory chip is firmly inserted into its socket. If the module is properly seated, reload the parameter data or perform a factory reset. Persistent InE errors point to internal control circuit failure.
What is the modern replacement path for the Lenze 8200 Vector series?
Lenze recommends the i550 series as the official successor to the phased-out 8200 Vector range. However, exact original replacement units like the E82EV753K4B201 allow direct drop-in maintenance without panel modification or software re-engineering.
