E82ZAFAC Lenze 8200-series Standard I/O Analog Application Module

Product Overview

The E82ZAFAC (E82ZAFAC) is a versatile I/O application module designed for the Lenze 8200 Vector and 8200 Motec series of frequency inverters. This module acts as a bridge between the inverter's internal processing and external control hardware, providing a comprehensive array of digital and analog connection points. In industrial B2B applications—such as synchronized multi-drive conveyors, dosing systems, and climate control automation—the E82ZAFAC is a critical component for integrating local sensors, potentiometers, and PLC signals. By utilizing this module, system engineers can achieve precise closed-loop speed control and complex logic sequences directly at the drive level. Although currently in its phase-out stage, the E82ZAFAC remains an essential resource for maintaining the flexibility and connectivity of existing 8200-series installations, offering German-engineered reliability in a compact, modular format.

Technical Configuration

The E82ZAFAC is architected for "hot-plug" integration into the standard AIF (Automation Interface) slot located on the front of the 8200-series drives. The module features a high-density terminal configuration, including 7 digital inputs for sequence control (e.g., start/stop, clockwise/counter-clockwise, fixed speeds) and 2 digital outputs for status signaling (e.g., "Ready" or "Fault" states). The analog section is equally robust, providing 2 analog inputs (0-10V or 0/4-20mA) for setpoint values or sensor feedback, and 2 analog outputs for visualizing actual values like motor frequency or current on external meters. Its ultra-compact 5 x 1 x 7 cm footprint and lightweight 0.12 kg build allow for maximum functionality without increasing the overall dimensions of the inverter unit.

Technical FAQs

How do I switch the analog inputs between voltage (0-10V) and current (4-20mA) signals?

The signal type for the analog inputs on the E82ZAFAC is typically determined by internal parameter settings within the 8200-series inverter (such as parameter C0034). Some hardware versions may also require the adjustment of miniature internal DIP switches or jumpers located on the module itself prior to installation.

Is the E82ZAFAC compatible with the newer i550 series?

No. The E82ZAFAC is specifically designed for the AIF slot architecture of the 8200-series. Newer Lenze drives like the i550 utilize a different modular interface system. To transition to newer technology, a complete drive and I/O module upgrade is required.

Can I use the digital inputs for high-speed counting?

While the digital inputs are optimized for standard control logic and switching, their sample rate is limited by the inverter's internal processing cycle. For high-speed pulse counting or positioning, specialized function modules or the 9300-series are generally recommended.

Engineering & Installation Guide

For successful installation of the E82ZAFAC, ensure the inverter is powered down before inserting the module into the AIF slot to prevent electrical transients. When wiring the analog inputs, use shielded twisted-pair cables to protect the low-voltage signals from electromagnetic interference generated by the motor cables. The shield should be grounded at the inverter's shield plate. To prevent signal noise, maintain a separation of at least 10 cm between the I/O wiring and the high-voltage power cables. Once installed, use the Lenze Global Drive Control (GDC) software or a plug-in keypad to assign the desired functions to the I/O terminals (e.g., assigning a specific digital input to "DC Braking" or an analog output to "Motor Torque").
