Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV302_4C is a 3.0 kW 3-phase AC frequency inverter from the 8200 Vector family, engineered for speed and torque control in demanding automation setups. Operating across an input voltage range of 320 to 550 V AC, this panel-mounted drive delivers a nominal output current of 7.3 A with an overload capacity up to 10.9 A for 60 seconds. It supports sensorless vector control and programmable V/f characteristics across an output frequency range of 0 to 480 Hz with an 8 kHz switching frequency, making it suitable for material handling systems, industrial fans, pumps, and packaging machinery.
Integrating a replacement drive into an existing control cabinet requires proper electrical termination and parameter cloning. Power is delivered through input terminals L1, L2, and L3, while output power connects to terminals U, V, and W. For high-inertia loads requiring dynamic braking, the unit includes an integrated braking transistor with dedicated RB1 and RB2 terminal connections for direct external resistor hookup. System expansion is supported via plug-in function slots that accommodate Lenze E82ZAF series fieldbus interfaces, such as CANopen and PROFIBUS-DP, alongside RS-232 and RS-485 serial communication. A replacement drive cannot run on factory defaults alone; parameter transfer must be performed using Global Drive Control (GDC) PC software or cloned directly using the non-volatile memory of the optional Keypad XT operating module. Technical support from ABC Industrial Parts can assist maintenance teams with configuration backups and parameter transfer.
Visual status monitoring is provided by a dual-color front LED indicator that flags operational states, including drive enable, inhibit, active warnings, and fault trips. Detailed fault memory is accessible through the Keypad XT readout codes C0161 and C0168 or via GDC software. Common line or load issues, such as DC bus overvoltage (OU), undervoltage (LU), or overcurrent conditions, can often be addressed by verifying supply lines, adjusting acceleration and deceleration ramps, or inspecting motor cabling. However, internal hardware failures, EEPROM memory corruption, or power module breakdowns cannot be serviced in the field. In these instances, sourcing a fully tested exchange unit or utilizing repair options through ABC Industrial Parts provides a direct route back to full production.

Programming and Configuration
Drive setup and parameter manipulation for the Lenze E82EV302_4C are handled primarily through Lenze Global Drive Control (GDC) commissioning software or the pluggable Keypad XT operating module (E82ZBC). The drive features non-volatile onboard memory capable of storing up to four complete, independent parameter sets. This multi-parameter structure allows operators to switch between different machine operating profiles or motor configurations without re-entering parameters.
During initial setup or commissioning, key parameters govern performance and protective thresholds. Acceleration ramp time is defined under parameter C0012, while deceleration ramp time is set under C0013. If a parameter corruption occurs or a reset to standard baseline settings is necessary, factory defaults can be restored by setting parameter C0002 to 1. When replacing a unit, parameter cloning can be executed directly via the Keypad XT module, transferring all operating parameters from the original drive to the replacement without requiring a PC connection.
Communication and System Integration
The modular hardware design of the Lenze 8200 Vector series separates the core power stage from control and communication functions. The E82EV302_4C base drive incorporates a modular front slot designed to accept various plug-in function and communication cards from the Lenze E82ZAF series. This allows straightforward retrofit or integration into centralized fieldbus architectures, including CANopen, PROFIBUS-DP, DeviceNet, and INTERBUS.
In addition to fieldbus expansion modules, standard RS-232 and RS-485 serial interfaces are supported for point-to-point PC diagnostics or master controller communication. Physical connection points on the terminal strip facilitate control inputs, thermal monitoring via motor PTC sensors, and external braking control using terminals RB1 and RB2 connected to the integrated braking transistor.
Diagnostics and Status Indication
The front face of the E82EV302_4C features a dual-color LED indicator providing real-time drive operational status. Green illumination signals ready or enabled states, while red illumination indicates active warnings or trip conditions. When the LED is off, it signals a loss of main AC input power or an internal power supply breakdown.
Detailed diagnostics and error tracking are stored in internal memory registers. Active fault codes and recent trip history can be retrieved through parameters C0161 and C0168 using either the Keypad XT module or Global Drive Control (GDC) software. System diagnostics allow engineers to distinguish between external line faults, load blockages, and internal hardware failures.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Fault LED | Green / Red - Green Blinking | Inverter ready / inhibited |
| Ready / Fault LED | Green / Red - Green Solid | Inverter running / enabled |
| Ready / Fault LED | Green / Red - Red Blinking | Warning condition active |
| Ready / Fault LED | Green / Red - Red Solid | Fault trip / drive disabled |
| Ready / Fault LED | Green / Red - Off | No power / internal supply failure |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV3024C frequency inverter, verify that the physical housing and electrical ratings match the installed unit. Ensure the mains supply falls within 320 to 550 V AC and that the replacement unit shares the exact E82EV3024C designation. Plug-in fieldbus modules (such as E82ZAF series CANopen or PROFIBUS cards) and Keypad XT operating units must be transferred from the original drive to maintain identical fieldbus addressing and connection compatibility.
A replacement unit will not function correctly in an existing system without parameter alignment. Operating parameters should be cloned using the Keypad XT module or downloaded via Global Drive Control (GDC) PC software. Ensure acceleration (C0012), deceleration (C0013), and motor nominal parameters are verified prior to enabling the drive under load.
For long-term modernization or system migration plans, Lenze identifies the i550 cabinet inverter series as the recommended migration successor. However, direct drop-in replacement with an identical E82EV302_4C spare unit avoids mechanical panel alterations, control rewiring, and PLC communication logic modifications.
