Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00490376, model type E82EV222_4C, is a 2.2 kW frequency inverter designed for precise speed and torque control of 4-pole AC asynchronous motors within the Lenze 8200 vector family. Built for control cabinet installation with an IP20 enclosure rating, this compact drive operates across a 3-phase supply voltage range of 320 V AC to 528 V AC at 400/480 V nominal. It delivers a continuous output current of 5.6 A and supports a 150% overload capacity up to 8.4 A for 60 seconds. The drive provides an output frequency range from 0 Hz to 480 Hz with an 8 kHz switching frequency, utilizing linear or square-law V/f control alongside sensorless vector modes for dynamic performance in material handling, conveyor systems, packaging machinery, and fan or pump drives.
Integrating the Lenze 00490376 into an existing machine relies on its modular design, which separates the power stage base unit from interchangeable function modules. Fieldbus integration and external I/O expansion are handled via plug-in modules such as the E82ZAFSC, E82ZAFCC, E82ZAFPC, or E82ZAFDC, supporting communication protocols like CANopen, PROFIBUS-DP, RS232/485 LECOM, and DeviceNet. Commissioning a replacement unit requires transferring operational parameters, as drives are not plug-and-play out of the box. Keypad modules such as the E82ZBC or E82ZBB XT, or Global Drive Control (GDC) software, are used to configure settings or upload stored parameter profiles. The internal EEPROM can hold up to four switchable parameter sets, allowing quick adaptation to different operating conditions. ABC Industrial Parts can support maintenance teams in sourcing the correct unit and backing up or transferring stored drive parameters.
Diagnostic status monitoring on the unit is provided through built-in front panel LEDs and software memory registers. A green LED indicates controller readiness or active motor operation, while a red LED signals warnings or fault trips. Detailed fault history is stored in internal parameters C0161 through C0164, accessible via keypad or fieldbus monitoring. The drive reports specific fault codes for events such as overcurrent during acceleration (OC1), deceleration (OC2), or steady speed (OC5), DC bus overvoltage (OU) or undervoltage (LU), heatsink overtemperature (OH), motor thermal overload (OH4), supply mains phase loss (LP1), and fieldbus communication loss (CE0). When hardware-level trip codes like H05 or internal memory errors occur, board-level faults cannot be serviced in the field. Sourcing a tested replacement or utilizing repair services through ABC Industrial Parts ensures a reliable return to operational status.

Programming and Configuration
The Lenze 00490376 frequency inverter utilizes Global Drive Control (GDC) software for engineering, parameter management, and system commissioning. Connection to a host PC is established via compatible LECOM RS232/485 communication adapters or fieldbus interface modules. GDC provides comprehensive visual access to drive parameters, dynamic diagnostics, and online control functions, streamlining setup and fine-tuning of motor control parameters.
For local parameter adjustment and operator control, the drive supports plug-in keypad units, including the standard E82ZBC keypad and the extended E82ZBB XT keypad. These plug-in modules fit directly onto the front function slot, enabling parameter modification, operational status checks, and fault history inspection without external software. The internal non-volatile EEPROM memory stores up to four independent parameter sets, which can be selected dynamically via digital inputs or fieldbus commands to accommodate varying product runs or operational modes.
Communication and System Integration
System integration with the Lenze 00490376 is achieved through its modular function module architecture. Rather than fixed, built-in communication terminals, the drive features a dedicated front slot that accepts plug-in fieldbus interface modules. Supported modules include the E82ZAFSC, E82ZAFCC, E82ZAFPC, and E82ZAFDC, which enable network connectivity over CANopen, PROFIBUS-DP, DeviceNet, and RS232/485 LECOM protocols.
This modular physical interface allows the drive to integrate directly into higher-level PLC architectures and distributed industrial networks. Network integration enables real-time speed setpoint transmission, drive enable commands, reading of diagnostic registers, and parameter read/write operations over the fieldbus. Proper communication setup requires configuring the corresponding bus address switches or software parameters to match network master configuration.
Diagnostics and Status Indication
The drive includes two integrated status LEDs on the front panel to provide immediate visual feedback on operational state and active conditions. The green LED signals drive readiness when flashing (controller inhibit active) and continuous motor operation when solid. The red LED flashes to indicate an active warning or impending trip condition, and illuminates continuously when a fault trip has occurred.
In addition to visual LED indications, the inverter maintains a historical error buffer within parameters C0161 through C0164, accessible via plug-in keypads (E82ZBC or E82ZBB XT) or GDC software. Diagnostic data and detailed error codes can also be read over CANopen or other fieldbus networks to assist centralized control systems with real-time fault tracking and root-cause analysis.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Flashing / Continuous | Flashing = Controller inhibit (IMP) / Ready; Continuous = Drive running / Enabled |
| Red LED | Red - Flashing / Continuous | Flashing = Warning / Active condition; Continuous = Trip / Active fault |
Replacement and Spare Part Considerations
When replacing a failed Lenze 00490376 (E82EV222_4C) drive, maintenance personnel must ensure that the existing plug-in function module (such as E82ZAFSC or E82ZAFPC) is transferred from the old unit to the replacement drive. Because the drive base unit contains the power section and main control board, transferring the fieldbus module preserves physical wiring connections while maintaining network node addresses if stored on hardware DIP switches.
A replacement drive must be loaded with the parameter configuration of the original unit prior to putting the machine back into service. Parameter profiles can be transferred by saving and loading settings via Global Drive Control (GDC) software or by utilizing a keypad module with copy capability. Because factory default settings will not match application-specific motor parameters, acceleration ramps, or I/O assignments, restoring a valid configuration backup is critical to prevent improper motor operation or fieldbus faults.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit / Overcurrent Acceleration | Output current exceeded overcurrent threshold during acceleration phase. | Short circuit or earth fault on motor cable; acceleration time set too short; motor damaged. | Check motor cable and winding insulation; increase acceleration time parameter; verify motor size. |
