Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00490461 (model E82EV371_2C) is a 0.37 kW AC frequency inverter from the Lenze 8200 vector family, engineered for speed, torque, and position control in automated machinery. Operating on an input supply range of 180 V to 264 V AC across single-phase or three-phase line feeds, this compact IP20-rated variable frequency drive delivers a continuous rated output current of 2.4 A at an 8 kHz switching frequency. It supports flexible motor control modes, including linear or quadratic V/f characteristic curves, dynamic sensorless vector control, and direct torque control. With a 150% dynamic overload reserve capable of supplying 3.6 A for up to 60 seconds, the drive is suited for demanding motor starting conditions in packaging lines, material handling conveyors, and industrial pump or fan systems.
The E82EV371_2C features a modular architecture that relies on pluggable function modules to define physical I/O terminals and network connectivity. When commissioning a replacement drive, field technicians must transfer or reconfigure the specific interface module—such as the E82ZAFSC Standard I/O, E82ZAFCC CANopen, or E82ZAFPC PROFIBUS module—to match the original installation. Drive parameters are managed using the Keypad XT (E82ZBC) operator panel or Lenze Global Drive Control (GDC) PC software. The inverter contains internal non-volatile EEPROM memory capable of holding up to four independent parameter sets. When replacing a damaged unit, parameters can be cloned directly from existing backups or extracted from donor memory, a service supported by ABC Industrial Parts to help minimize machine downtime.
Operational monitoring and troubleshooting are supported through dual LED status indicators on the front panel alongside internal diagnostic buffers. A green LED signals power and operational state, while a red LED indicates warnings or active trip faults. Detailed fault diagnosis is accessible via the Keypad XT display, GDC software diagnostic windows, or the internal fault history buffer spanning memory locations C0161 to C0164. Common issues such as acceleration overcurrent (OC1) or DC bus overvoltage (OU) can often be resolved by adjusting acceleration (C0012) or deceleration (C0013) ramp times. If persistent hardware errors like EEPROM corruptions (EEH) or power stage defects (H05) occur, internal component repairs are required. In these situations, sourcing a fully tested replacement drive or utilizing expert repair services through ABC Industrial Parts ensures swift production recovery.

Programming and Configuration
Configuring the Lenze 00490461 frequency inverter is accomplished using either the plug-in Keypad XT (E82ZBC) display panel or Lenze Global Drive Control (GDC) engineering software connected via a PC interface. The unit features non-volatile internal EEPROM memory that stores up to four complete, independent parameter sets, allowing multi-purpose application configurations within a single drive.
During setup and commissioning, key operating parameters can be adjusted to optimize motor control and drive dynamics. Critical parameter codes include C0012 for setting acceleration ramp times and C0013 for deceleration ramp times. Field technicians can quickly download parameter backups to GDC software or copy stored parameter profiles directly between drives using the Keypad XT module.
Communication and System Integration
The Lenze 8200 vector series utilizes a pluggable Function Module (FIF) system to integrate the drive into automated control architectures. The base E82EV371_2C inverter unit requires an attached interface module to establish control terminal signals or fieldbus connection points.
Supported expansion interface options include the E82ZAFSC Standard I/O module for hardwired digital and analog control, the E82ZAFCC module for CANopen networking, and the E82ZAFPC module for PROFIBUS-DP connectivity. System integrators can also utilize LECOM and Modbus RTU protocol modules to enable serial communication across broader automation networks.
Diagnostics and Status Indication
The drive provides status indication via front-panel LEDs alongside parameter-based diagnostic monitoring tools. Real-time diagnostic data can be viewed through the Keypad XT text display, the GDC software diagnostic window, or by monitoring internal status words.
For historical fault analysis, the drive records recent trip events in a designated fault history buffer across parameters C0161 through C0164. This allows maintenance personnel to review fault sequences and diagnose recurring operational issues.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Power (Green LED) | Green - Blinking / Solid | Blinking: Mains supply connected and inverter ready. Solid: Drive operational / enabled. |
| Fault / Trip (Red LED) | Red - Blinking / Solid | Blinking: Warning or trouble condition detected. Solid: Critical fault / trip active, power stage disabled. |
Replacement and Spare Part Considerations
When swapping out a failed Lenze 00490461 drive, care must be taken to match both the base power section and the installed pluggable function module. The replacement drive chassis must match the 0.37 kW 230V specifications of the E82EV371_2C model to ensure correct thermal and electrical ratings.
Before putting a spare unit into operation, the existing function module (such as E82ZAFSC, E82ZAFCC, or E82ZAFPC) must be transferred to the replacement unit, or an equivalent module must be installed and configured. Parameter settings stored in the internal EEPROM must be uploaded to the replacement drive using either the Keypad XT panel or GDC software to restore original machine operations.
For modern system retrofits or complete machine upgrades where legacy 8200 vector units are being phased out, Lenze recommends the i510 or i550 inverter series as direct successor platforms. However, installing a direct-replacement 00490461 unit avoids panel wiring modifications and control program alterations.
