Lenze 13187847 E82MV751_4B001 – 8200 Motec Frequency Inverter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13187847 (model E82MV751_4B001) is a 0.75 kW frequency inverter from the 8200 motec and 8200 vector drive family designed for decentralized motor control. Engineered with an IP65 protection rating, this frequency inverter mounts directly onto motor terminal boxes, machine frames, or nearby surfaces, eliminating the space requirements and cabling complexity of centralized control cabinets. Operating on a 3-phase AC input from 320 V to 528 V AC at 45 to 65 Hz, the unit provides a rated output current of 2.4 A and an output frequency range up to 480 Hz. Motor speed and torque are managed using sensorless vector control, standard linear V/f, or quadratic V/f characteristic curves, with adjustable switching frequencies between 2 kHz and 16 kHz to optimize acoustic noise and thermal efficiency.
Connecting and commissioning a replacement Lenze E82MV751_4B001 drive relies on a modular architecture that pairs the base power unit with pluggable function modules. Network integration is supported via option modules including the E82ZAFCC010 CANopen module, E82ZAFPC010 PROFIBUS-DP module, E82ZAFAC010 AS-Interface module, and E82ZAFSC010 RS-232/485 serial module. Drive commissioning and parameter cloned transfer are streamlined by swapping the removable E82ZEM memory chip from the existing drive directly into the spare unit, enabling full parameter restoration without requiring a programming PC. Before re-energizing the system, hardware address settings, fieldbus cabling, and communication card seating must be verified. ABC Industrial Parts can assist in sourcing compatible spare units and parameter memory modules to ensure minimal interruption to operations.
Diagnostics are provided on the unit via dual-color LED indicators and internal software monitors. A solid green light indicates active drive operation and readiness, while a blinking green light signifies a active controller inhibit state. A blinking red light warns of non-permissible operating conditions, whereas a solid red light indicates an active TRIP fault condition. Detailed diagnostic records are stored in the TRIP history buffer under parameter C0168 and can be extracted using the E82ZBC operating keypad or Lenze Global Drive Control (GDC) software. Common field trip events include output short circuits (OC1, OC2), earth faults (OC3), DC bus overvoltage (OU), and motor thermal overload (OH3, OH4). Internal hardware processing faults such as C09 reflect component-level faults that cannot be serviced in the field; resolving these conditions requires power cycling, complete drive replacement, or unit evaluation with ABC Industrial Parts.

Programming and Configuration
The Lenze E82MV751_4B001 frequency inverter is programmed and configured using the Lenze Global Drive Control (GDC) software tool or the pluggable E82ZBC operating keypad. Through GDC, engineers can adjust motor parameters, set acceleration and deceleration ramps, configure custom V/f characteristic curves, and monitor real-time operating signals using the built-in oscilloscope function.
Parameter management and drive replacement are simplified by the removable E82ZEM memory module. Application parameter sets stored on the E82ZEM memory chip can be transferred directly to a replacement unit without establishing a software connection. If a memory checksum error occurs, represented by error code EER, reloading factory default settings or replacing the E82ZEM module restores normal parameter storage functionality.
Communication and System Integration
Network integration for the Lenze 13187847 drive is managed via modular plug-in cards fitted into the unit's function slot. Fieldbus compatibility includes CANopen via the E82ZAFCC010 module, PROFIBUS-DP via the E82ZAFPC010 module, AS-Interface via the E82ZAFAC010 module, and RS-232/485 serial communications using the E82ZAFSC010 module.
When installing or swapping communication modules, proper mounting alignment and screw torque are necessary to ensure electrical contact and maintain IP65 environmental sealing. Communication loss or interface timeout errors generate fault code CE0, requiring inspection of module seating, bus wiring, and network termination.
Diagnostics and Status Indication
Drive status is indicated on the housing via dual-color LEDs. The green LED indicates drive operational state and controller availability, while the red LED indicates active TRIP fault conditions or operating warnings.
Advanced diagnostic tools include the TRIP history memory buffer accessed via parameter C0168, which logs historic fault records. System status monitoring, error evaluation, and oscilloscope functions can also be performed via an attached E82ZBC Keypad or GDC online software connection.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid / Flashing | Continuous ON indicates active TRIP fault state; blinking indicates warning or impermissible operating condition. |
| Green LED | Green - Solid / Flashing | Continuous ON indicates drive operation / ready for operation; blinking indicates controller inhibit active. |
Replacement and Spare Part Considerations
When replacing an E82MV751_4B001 frequency inverter, verify that the replacement hardware matches the 0.75 kW power rating and IP65 enclosure specification to maintain environmental protection in washdown or outdoor installations.
To complete a parameter transfer without a PC, remove the E82ZEM memory module from the original drive unit and install it into the replacement inverter prior to powering on. Re-attach any installed fieldbus communication modules, ensuring that DIP switch address settings and terminal connections match the original installation.
