Overview

The KEB 16.F4.115-G438 Inverter Rectifier Board is a crucial component in the KEB COMBIVERT F4 series frequency inverters. It combines two essential functions:

1. AC-to-DC Rectification: Converts incoming AC voltage to DC for the inverter's output stage.

2. I/O Control Interface: Handles digital and analog control signals (e.g., speed references, start/stop commands, relay outputs).

The -G438 option indicates that the board is configured for specialized control or I/O configurations, suited for advanced motion control or customized drive interaction.

Technical Data

Applications

• Material Handling & Conveyors: Controls start/stop commands and speed setpoints while supplying the necessary power for motor operation.

• Specialized Machinery: Used in lift, textile, or printing applications requiring customized I/O sequencing or signaling.

• Motor Braking Control: Digital outputs manage external motor brakes, especially in vertical applications, to ensure safe operation.

FAQ

• Q1: What does the rectifier section do?
  A1: It converts AC mains voltage into DC to power the inverter, which then drives the motor with variable frequency.

• Q2: Why integrate I/O functionality on the rectifier board?
  A2: This simplifies the system architecture and reduces the need for additional interface boards, making the drive more compact and cost-effective.

• Q3: What happens if I use a different FA revision number?
  A3: A different revision may cause compatibility issues due to minor component changes, altered I/O mappings, or circuit protection values.

• Q4: What software is used to test the I/O points?
  A4: KEB COMBIVIS software is used to monitor and test the board's I/O points, enabling diagnostics and parameter adjustments.
