Product Short Description
Product Name: PROFIBUS-DP Communication Interface Module (E82ZAF series)
Product Introduction: The E82ZAFP is a communication function module in the Lenze E82ZAF family, specifically designed to connect Lenze 8200 vector, 8200 motec, and starttec drive series to PROFIBUS-DP industrial fieldbus networks. It plugs into the AIF slot of compatible Lenze standard devices.
Description

- Connections: Terminal strip X3 with PROFIBUS (A/B), external 24 V supply, and CINH (controller inhibit) interface
Functional Features:
- Automatic baud rate detection across the full PROFIBUS-DP range
- External 24 V supply ensures the PROFIBUS network stays active even when the drive power fails
- DIP-switch-activated bus termination
- LED diagnostics for quick troubleshooting
Application Scenarios: Used in industrial automation systems where Lenze drives must be integrated into PROFIBUS-DP networks for centralized PLC control, particularly in manufacturing, material handling, and process control systems.
Working Principle: The module translates between the internal drive communication protocol and the PROFIBUS-DP-V0 standard. It acts as a slave node on the PROFIBUS network, exchanging process data (setpoints, actual values) and parameter data with the master PLC. The external 24 V supply powers the module independently so that network communication is maintained even if the drive’s main power is lost.
Installation Requirements: Insert into the AIF slot of a compatible Lenze 8200 vector, 8200 motec, or starttec device. Wire the PROFIBUS A/B lines to the network using proper PROFIBUS cable with shielding. If this module is at the end of a bus segment, activate the terminating resistor via the DIP switch. Provide a dedicated 24 V DC supply for the X3.2 terminal if bus-active-on-drive-failure is required.
Usage Precautions: Always use a separate, safely isolated (SELV/PELV) power supply for external voltage according to EN 61800-5-1. Ensure correct bus termination to avoid signal reflection. The module contains electrostatically sensitive components—observe ESD precautions during handling.
