Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV752_4C200 is a 7.5 kW frequency inverter from the 8200 Vector series designed for precise speed control and torque management of three-phase AC motors. Operating on a 3-phase mains supply voltage from 320 V AC to 528 V AC, this enclosure-mounted drive delivers a rated continuous output current of 16.5 A and provides a peak overload current of 24.8 A for up to 60 seconds. Housed in an IP20 enclosure, the unit features an integrated Class A radio interference filter that suppresses line-bound electromagnetic emissions without needing additional external panel space. It supports both sensorless vector control and V/f characteristic control across an output frequency range of 0 to 480 Hz with a default switching frequency of 8 kHz.
Putting a replacement drive into service requires matching the physical power rating and transferring any attached control hardware from the original installation. The E82EV752_4C200 utilizes a modular system architecture that cleanly separates the base power section from user control options, accommodating plug-in modules such as the Standard I/O Function Module (E82ZAFSC), CANopen (E82ZAFCC), PROFIBUS-DP (E82ZAFPC), or LECOM RS485 communication cards. Replacement units are rarely plug-and-play and require parameter setup; up to four independent parameter sets stored in internal non-volatile EEPROM memory must be loaded using either the Keypad XT (E82ZBC) handheld module or Lenze Global Drive Control (GDC) PC software. Maintenance personnel seeking support during configuration transfer or spare preparation can consult ABC Industrial Parts for operational exchange units and technical assistance.
Drive status and fault conditions are monitored through front-panel LED indicators, digital status word inspection via fieldbus connections, and active fault history code logs under parameter C0168. A solid green OK LED indicates normal enabled operation, while a flashing green LED signifies controller inhibit or standby. The red FLT LED illuminates solid during active inverter trips and flashes rapidly for active warnings; persistent illumination across power cycles indicates an internal control hardware condition. While field faults such as heatsink overtemperature (OH), line phase loss (LP1), or DC bus overvoltage (OU) can be resolved by checking cooling fans, mains supply, or braking resistors, internal board failures (H05) and persistent EEPROM corruptions (EE0) require shop repair. ABC Industrial Parts provides tested replacement drives and repair services to minimize system downtime.

Programming and Configuration
Programming and parameter management for the Lenze E82EV752_4C200 inverter are performed using either Lenze Global Drive Control (GDC) PC software or the plug-in Keypad XT (E82ZBC) operating module. The inverter contains non-volatile EEPROM memory configured to hold up to four complete, independent parameter sets, enabling flexible setup changes for multi-recipe machines or varied motor operating profiles.
Commissioning a new unit involves writing motor parameters, speed ramp times (C0012 acceleration and C0013 deceleration), switching frequency parameters, and fieldbus node addresses. In instances where parameter structures become corrupted, a factory reset can be executed via parameter C0002. Parameter files saved in GDC software can be uploaded directly to a spare unit to ensure identical dynamic performance to the original drive.
Communication and System Integration
The Lenze 8200 Vector series uses a modular interface slot (FIF) that separates fieldbus hardware from the main drive control board. The E82EV752_4C200 supports a range of swap-in function modules, including the Standard I/O Function Module (E82ZAFSC) for hardwired analog and digital control schemes.
For higher-level network integration with industrial PLCs, optional communication modules can be installed into the slot. These include the CANopen Function Module (E82ZAFCC), PROFIBUS-DP Function Module (E82ZAFPC), and LECOM RS485 modules. These interfaces allow cyclic transmission of control signals, velocity setpoints, status word feedback, and direct parameter editing over the automation network.
Diagnostics and Status Indication
The E82EV752_4C200 incorporates real-time visual LED status indicators on its front panel alongside digital diagnostic routines. Diagnostic data can be evaluated via fieldbus network status words or read out as active fault history codes under parameter C0168 using GDC software or the Keypad XT module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (FLT) | Red - Solid or Flashing | Solid lit indicates an active inverter fault or trip state requiring reset. Fast flashing indicates an active warning. Persistent illumination across power cycles suggests an internal control hardware fault. |
| Green LED (OK) | Green - Solid or Flashing | Solid green indicates drive is operational and enabled. Flashing green indicates controller inhibit (IMP) or standby state. |
Replacement and Spare Part Considerations
When replacing a failed Lenze E82EV752_4C200, verify that the replacement drive matches the required 7.5 kW power rating, 320-528 V AC 3-phase supply input, and the version C integrated Class A RFI filter suffix. The modular nature of the 8200 Vector series allows maintenance technicians to detach the existing plug-in function module (e.g., PROFIBUS-DP or CANopen) and Keypad XT from the faulty unit and transfer them directly onto the replacement base unit.
A replacement inverter will not run without proper parameter transfer. Before placing a replacement drive into active service, restore its configuration using a Global Drive Control (GDC) software parameter backup file or transfer the parameter sets stored on the Keypad XT module. For new system designs or complete control system modernizations, the Lenze i550 cabinet drive serves as the recommended successor series.
