Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV751_4C200 is a 0.75 kW frequency inverter from the 8200 Vector series, engineered for precise variable speed and torque control of three-phase AC motors in industrial machinery. Operating on a 3-phase AC supply voltage ranging from 320 V AC to 528 V AC, the drive delivers a continuous output current of 2.4 A at 400 V with a short-time overload capability of 150% rated torque for up to 60 seconds. This specific model variant (suffix 200) is built without an integrated RFI/EMI interference suppression filter, making it suitable for cabinet installations utilizing central external line filters. Motor control capabilities encompass standard V/f characteristic control as well as sensorless vector control across an adjustable output frequency range of 0 Hz to 480 Hz.
Putting a replacement unit into service requires matching the basic drive specification and transferring operational parameters to ensure proper machine function. Operational setups can be replicated using the E82ZMC plug-in memory card, the E82ZBC XT keypad operator module, or PC-based commissioning via Global Drive Control (GDC) software version 3.x or higher. Network integration is handled through the modular AIF/FIF plug-in function slot, which accepts interface modules for CANopen (E82ZAFCC), PROFIBUS-DP (E82ZAFPC), DeviceNet, or INTERBUS fieldbus protocols. Where parameter extraction from a faulty board or donor unit is required, ABC Industrial Parts provides technical support to streamline spare unit commissioning and prevent prolonged downtime.
Diagnostic conditions are shown locally via front-panel green and red LED status indicators. A blinking green LED signifies that the drive is ready with controller inhibit active, while a solid green light indicates active drive operation. Warnings cause the red LED to blink, whereas TRIP faults cause a solid red illumination and shut down the inverter power stage. When a solid red light persists alongside an inactive green LED following a system reboot, internal hardware corruption or component failure is indicated. Because internal hardware errors such as fault code H05 are not field-serviceable, replacing the unit or sourcing a tested exchange drive through ABC Industrial Parts offers a direct path back to full production.

Programming and Configuration
The Lenze E82EV751_4C200 inverter supports parameter management and system setup through multiple hardware and software interface options. The internal controller features non-volatile memory capable of storing up to four independent, switchable parameter sets. This internal structure allows a single inverter to switch between different operational profiles, motor profiles, or process routines without re-uploading parameters during runtime.
For direct PC configuration and monitoring, the drive connects to Global Drive Control (GDC) software version 3.x or higher. Rapid field replacement without a PC is accomplished using the optional E82ZMC plug-in memory card or the E82ZBC XT keypad operator module. Inserting a pre-programmed E82ZMC memory card transfers parameter sets directly to the drive. If parameter memory corruption occurs, parameter C0002 can be set to 1 to reload factory default parameters before restoring machine-specific settings.
Communication and System Integration
System integration on the Lenze E82EV751_4C200 relies on a modular plug-in function slot utilizing the AIF/FIF interface architecture. This modular design isolates the core frequency inverter hardware from fieldbus physical layers, allowing the unit to adapt to various network topologies by selecting the matching plug-in function module.
Compatible communication hardware includes the E82ZAFCC module for CANopen networks and the E82ZAFPC module for PROFIBUS-DP, alongside optional modules for DeviceNet and INTERBUS systems. The interface handles process data communication, speed references, and host PLC control word signals. Internal diagnostic monitoring continuously checks communication health; a missing or unseated module triggers code CE0, while fieldbus process data timeout triggers code CE1.
Diagnostics and Status Indication
Local operational status monitoring for the E82EV751_4C200 is provided by front-panel green and red status LEDs, supplemented by diagnostic memory parameters. The green LED indicates controller operational states, while the red LED indicates warning or TRIP fault conditions. A solid red LED accompanied by an inactive green LED following power-up points to an unrecoverable internal hardware or processor failure.
In addition to visual LED indicators, full fault history details are stored in the internal TRIP memory register accessible via parameter C0168. Technicians can interrogate code history using the E82ZBC XT keypad or through the diagnostic monitor built into Global Drive Control (GDC) software. Status word inspection over active fieldbus connections also provides continuous diagnostic feedback to higher-level controllers.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready) | Green - Blinking | Drive ready, controller inhibited. |
| Green LED (Ready) | Green - Solid ON | Controller enabled / operation active. |
| Red LED (Fault) | Red - Blinking | Warning present. |
| Red LED (Fault) | Red - Solid ON | TRIP fault active / Inverter switched off due to error. If solid ON and green off continuously after reboot, indicates possible internal hardware failure. |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV751_4C200 inverter, maintenance technicians must pay careful attention to the part number suffix. The 4C200 designation specifies a unit manufactured without an internal RFI/EMI interference suppression filter. Installing a variant with different filtering characteristics or installing this unit in a panel lacking external line filtering can affect electromagnetic compliance and system operation.
To complete a drive swap, transfer any existing plug-in function module (such as the E82ZAFCC CANopen or E82ZAFPC PROFIBUS module) from the failed inverter to the replacement unit. Parameter profiles can be transferred directly using an existing E82ZMC plug-in memory card or uploaded via Global Drive Control (GDC) software. For long-term migration planning beyond the 8200 Vector platform, Lenze recommends transitioning to the i550 cabinet inverter series, with model i55AE175F1001000S serving as the direct functional successor.
