Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV251_2C200 is a compact 0.25 kW (0.34 HP) frequency inverter from the 8200 Vector series, engineered for precise variable speed control of asynchronous AC motors. Operating from a single-phase or three-phase supply voltage range of 180 V AC to 264 V AC, this IP20-rated cabinet drive delivers a continuous rated output current of 1.7 A and a maximum output current of 2.5 A. Control method options include sensorless vector control, standard V/f characteristic control, and torque control across an output frequency range from 0 Hz to 480 Hz. Designed without an integrated EMC filter, this specific chassis unit is intended for installation in control cabinets where external mains filtering is already provided.
Featuring a modular system architecture, the drive power unit operates alongside snap-in control interface modules and optional fieldbus adapters. Swapping a unit or commissioning a spare spare component requires transferring the front-mounted control module—such as an E82ZAFSC Standard I/O interface, an E82ZAFPC PROFIBUS-DP adapter, or an E82ZAFCC CANopen module—and transferring the drive parameters. Configuration data is structured under Lenze standardized C-parameter codes and can be rapidly duplicated using the removable memory unit, an E82ZBC keypad module, or Global Drive Control (GDC) PC software. Technicians preparing a spare unit can rely on ABC Industrial Parts to source tested drive hardware and assist with parameter extraction or interface module verification.
Local drive status is indicated by front-panel status LEDs that report power readiness, operating state, warnings, and active TRIP conditions. Internal software continuously monitors operating limits, logging fault events into the C0168 fault history buffer, which can be read using an attached keypad or PC setup tool. Typical trip causes include overcurrent on acceleration (OC1), DC bus overvoltage (OU), or DC bus undervoltage (LU). If the drive displays hardware codes such as H10 or H11, indicating an internal board or processor fault, field repairs are not possible; exchanging the faulty inverter with a fully tested unit through ABC Industrial Parts ensures a rapid return to production.

Programming and Configuration
The E82EV251_2C200 uses the standardized Lenze C-parameter matrix to manage motor parameters, acceleration profiles, control methods, and fieldbus mappings. Parameters such as acceleration time (C0012), deceleration time (C0013), and maximum frequency (C0011) allow precise tuning for specific mechanical loads. The drive supports a 150% overload capacity for up to 60 seconds, which is configured and monitored via internal thermal motor models (C0075 and C0076).
Parameter management and drive commissioning can be executed via the plug-in E82ZBC keypad module or through Lenze Global Drive Control (GDC) software on a PC. When replacing an existing inverter, the pluggable memory chip allows direct parameter cloning between units without re-entering parameters manually. If a parameter set becomes corrupted or inconsistent, resetting the drive to factory default settings via C0002 enables a clean re-commissioning process.
Communication and System Integration
Integration into fieldbus networks and automated control systems is accomplished using plug-in function and communication modules attached to the front Automation Interface (AIF) slot. The drive hardware is compatible with standard modules including the E82ZAFSC Standard I/O module for hardwired terminal control, the E82ZAFPC module for PROFIBUS-DP, and the E82ZAFCC module for CANopen system bus integration. Additional network options such as Modbus RTU and EtherCAT are also supported through appropriate snap-in interfaces.
When configured on a network, status word inspection and control commands are exchanged continuously across the fieldbus interface. Proper physical installation requires securing the function module into the AIF slot to prevent contact issues. On CANopen and System Bus installations, verifying bus cable connections, baud rate alignment, and correct termination resistor placement is required to prevent communication timeouts.
Diagnostics and Status Indication
The drive features two status LEDs on the front panel that provide real-time visual feedback on operating state and active trip conditions. A green LED indicates power status and operational readiness, turning solid green when the inverter is enabled and running. A red LED indicates warning states or active TRIP faults, illuminating solid red during an active inverter fault and flashing when a start inhibit or warning condition is present.
In addition to LED indications, detailed fault diagnostics can be extracted from the C0168 fault history buffer using the E82ZBC keypad or GDC engineering software. The system monitors parameters such as heatsink temperature, motor overload conditions, DC bus voltages, and fieldbus communication integrity to maintain operational safety.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid / Flashing | TRIP active / Fault state. Solid red indicates inverter fault; flashing indicates warning or start inhibit. |
| Green LED | Green - Solid / Flashing | Operation / Ready. Solid green indicates inverter is enabled and operating; flashing indicates power on / ready state. |
Replacement and Spare Part Considerations
When replacing a failed E82EV251_2C200 inverter, ensure that the part number matches the required chassis configuration. The '200' suffix indicates that this unit does not contain an integrated EMC filter. Installing a unit without an EMC filter in an installation designed for integrated filtering may result in electromagnetic interference unless external mains filters are present.
Before applying power to the replacement drive, swap the function or fieldbus interface module (e.g., E82ZAFSC, E82ZAFPC, or E82ZAFCC) from the original unit onto the new power stage. Parameter settings must then be loaded via the plug-in memory chip or uploaded using the E82ZBC keypad module or GDC software to ensure correct motor parameters, operational limits, and fieldbus node addresses.
For long-term modernization planning or complete system overhauls, Lenze i510 and i550 cabinet inverter series serve as official successor lines for legacy 8200 vector installations. However, direct drop-in replacement with an identical E82EV251_2C200 remains the fastest method to restore operation without panel modification or wiring redesign.
