Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV402_4C is a 4.0 kW (5.5 HP) frequency inverter from the 8200 vector series, designed for speed and torque regulation of standard three-phase asynchronous motors. Operating on a three-phase AC supply from 320 V AC to 528 V AC across 45 to 65 Hz, this IP20-rated variable frequency drive delivers a rated output current of 9.5 A at 400 V AC and can support short-term peak overloads up to 14.3 A for 60 seconds. The drive provides an output frequency range from 0 to 480 Hz using linear V/f, square-law V/f, or Sensorless Vector Control (SLVC) modes, making it suitable for dynamic industrial equipment including material handling conveyors, industrial pumps, fans, and packaging systems.
To integrate into existing control systems, the base unit features a modular design with a dedicated slot for plug-in function modules (FIF), accommodating options such as Standard I/O (E82ZAFSC), CANopen (E82ZAFCC), or PROFIBUS DP (E82ZAFPC). Integrated DC bus terminals support dynamic braking chopper connection and energy sharing across shared DC links. Commissioning a replacement unit requires restoring the parameter configuration, as up to four internal parameter sets can be stored on the drive. Parameter transfer is performed using either the Keypad XT E82ZBC operator panel or Global Drive Control (GDC) PC software. ABC Industrial Parts can support maintenance teams with parameter extraction and replacement drive preparation to minimize machinery downtime.
Comprehensive visual and system diagnostics assist in rapid fault identification on the factory floor. A dual-color Ready / Fault LED on the front face reflects real-time status, distinguishing between drive enable, inhibit, warning, and fault states. Detailed operating data and a fault history buffer can be accessed via parameter C0183 and parameter C0161. When confronting persistent overcurrent or hardware memory errors, internal driver or component failures cannot be serviced in the field; installing a fully tested replacement drive through ABC Industrial Parts provides an effective solution to restore production.

Programming and Configuration
The Lenze E82EV402_4C frequency inverter utilizes parameter-based management supporting up to four independent internal parameter sets. This feature allows different operating profiles to be saved directly on the drive and switched during machine setup. Software configuration is conducted through Lenze Global Drive Control (GDC) software version 4.x or higher, connected via appropriate communication adapters.
For direct manual parameter adjustment and status monitoring, the optional Keypad XT E82ZBC operator module plugs directly into the drive interface. Parameter cloning can be performed using the Keypad XT or GDC software to read out existing settings from a functioning or donor unit and download them to a replacement drive. Restoring factory settings can be performed by setting parameter C0002 to 1 followed by a power cycle.
Communication and System Integration
System integration for the E82EV402_4C is achieved via interchangeable plug-in function modules (FIF) installed into the drive's dedicated front expansion slot. Network options include standard I/O modules (E82ZAFSC), CANopen interface modules (E82ZAFCC), PROFIBUS DP interface modules (E82ZAFPC), DeviceNet modules (E82ZAFDC), and INTERBUS modules (E82ZAFIC).
In addition to fieldbus interface slots, the unit includes integrated DC bus terminals (+UG, -UG). These connections allow multiple drives to share a common DC link for regenerative energy balancing or connection to external dynamic braking choppers and resistors during high-inertia braking operations.
Diagnostics and Status Indication
Diagnostic evaluation on the drive is supported through hardware status indication and software monitoring tools. Parameter C0183 displays the current operational state in real time, while parameter C0161 maintains a historic fault memory buffer for recording previous trip events and troubleshooting intermittent issues.
A dual-color LED on the front panel provides direct status feedback without requiring external diagnostics software. The combination of green and red illumination states signals operational readiness, active enable, system warnings, or active trip faults.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Fault LED | Green / Red - Green flashing: Drive ready/inhibit | Green solid: Drive enabled/operating | Red flashing: Warning active | Red solid: Fault/TRIP active | Indicates overall operating status, readiness, warnings, or fault conditions |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV402_4C drive, verify that the physical function module (e.g., E82ZAFSC, E82ZAFCC, or E82ZAFPC) is transferred from the old drive or equipped identically on the replacement unit. Ensure node addresses, DIP switches, and bus termination resistors on the function module match the original installation.
Because a new or spare drive contains default factory parameters, running the drive without transferring the application parameters can result in improper control or fieldbus errors. Parameter sets should be cloned using the Keypad XT E82ZBC or GDC software v4.x+. When upgrading control panels to current technology, the Lenze i550 cabinet inverter (model i550-C4.0/400-3) represents the official migration path.
