Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00490410, model designation E82EV251_2C, is a compact 0.25 kW frequency inverter from the Lenze 8200 vector product family. Designed for precise speed and torque regulation of three-phase AC motors, this drive operates on a supply voltage range of 180 V to 264 V AC across single-phase or three-phase line feeds (45 to 65 Hz). The unit provides a rated continuous output current of 1.7 A at up to 230 V AC, supported by a 150% overload capacity delivering 2.55 A for up to 60 seconds to handle high starting torque demands. Operating with an output frequency range from 0 to 480 Hz and selectable switching frequencies between 2 kHz and 16 kHz (8 kHz default), it is widely deployed in material handling conveyors, packaging machinery, small pumps, and industrial fan applications.
Integration and replacement within control cabinets are straightforward due to the modular slot architecture of the 8200 vector series, which separates the power base unit from detachable function and communication modules. Supported option cards include CANopen (E82ZAFCC / E82ZAFSC010), PROFIBUS-DP (E82ZAFPC), and LECOM RS-232 (E82ZAL01), as well as INTERBUS and RS-485 interfaces. Commissioning a replacement unit requires matching the hardware module and loading the drive settings. Non-volatile internal EEPROM memory holds up to four complete parameter sets, which can be extracted or uploaded using the XT Keypad (E82ZBC) or Lenze Global Drive Control (GDC) software. ABC Industrial Parts can assist in parameter backup recovery, module alignment, or sourcing pre-configured replacement units.
System state monitoring and troubleshooting rely on two fascia-mounted multi-state LEDs alongside comprehensive diagnostic registers. Real-time parameters display active status codes (C005x), DC bus voltage, and output current, while an internal fault buffer stores the last four TRIP events across parameters C0161 to C0164. When external checks of the mains supply, motor wiring, and fieldbus connections do not resolve active TRIP faults, hardware issues such as internal EEPROM failure (EER) or control board faults (H05) require specialized service. ABC Industrial Parts offers rapid repair services and fully tested exchange units to restore production without unnecessary downtime.

Programming and Configuration
Drive configuration for the Lenze 00490410 E82EV251_2C is managed using either the detachable XT Keypad (E82ZBC) or Lenze Global Drive Control (GDC) software via a PC connection. The internal non-volatile EEPROM architecture can retain up to four distinct parameter sets, permitting rapid switching between pre-configured operational profiles or serving as an onboard configuration backup.
Commissioning involves setting motor nameplate parameters, defining speed ramps, establishing switching frequency (from 2 kHz to 16 kHz), and choosing the control characteristic (linear V/f, quadratic V/f, or sensorless vector control). When swapping out a failed drive, parameter sets should be transferred from the original unit using GDC software or the XT Keypad to mirror exact machine behavior.
Communication and System Integration
The Lenze 8200 vector series utilizes a flexible modular slot interface that decouples communication options from the base power housing. This allows the E82EV251_2C to connect seamlessly to standard industrial communication networks by swapping plug-in fieldbus modules.
Supported expansion options include CANopen modules (E82ZAFCC / E82ZAFSC010), PROFIBUS-DP modules (E82ZAFPC), LECOM RS-232 modules (E82ZAL01), as well as INTERBUS and RS-485 interfaces. Integrating the drive into a fieldbus architecture requires setting the node address, selecting matching baud rates, and ensuring proper network termination on the plug-in communication card.
Diagnostics and Status Indication
Diagnostic feedback on the E82EV251_2C combines dual front-panel LEDs with digital parameter monitoring accessible through the XT Keypad display or GDC software. Real-time parameters allow technicians to inspect operating codes (C005x status registers), output current, and internal DC bus voltage during troubleshooting.
For tracking intermittent faults, the drive features an internal fault buffer that records the four most recent TRIP conditions in parameters C0161 through C0164. Visual status is provided continuously via the Operation/Ready green LED and Fault red LED.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation / Ready) | Green - Multi-state | Off: Supply voltage missing or internal power failure; Blinking slow (1 Hz): Controller inhibit active; On steady: Controller active and operational. |
| Red LED (Fault) | Red - Multi-state | On steady: TRIP fault active; Blinking: Warning active. |
Replacement and Spare Part Considerations
The Lenze 00490410 E82EV251_2C provides a exact dimensional and physical replacement for existing 8200 vector installations. Replacing a damaged unit requires no electrical panel structural changes or mounting modifications.
When installing a spare drive, technicians must move the plug-in communication card (such as CANopen or PROFIBUS-DP) from the original unit to the new housing and reload the matching parameter profile into memory. Verifying parameter sets and matching switching frequencies ensures safe operation and identical control dynamics.
