This document provides information about the G7F-ADHA A/D-D/A module for use with GM7 and MASTER-K80S PLCs. It can convert analog inputs like voltage and current to 12-bit digital values, and convert digital values to analog outputs. Specifications and characteristics of the analog input and output are provided. Examples show how to control an inverter's frequency using 0-10VDC or 4-20mA control signals from the module. Wiring diagrams, programming examples, and attached documents are included to help interface the module with an inverter. Frequently asked questions about the module and interfacing with an inverter are also listed.

2. Introduction
The G7F-ADHA is A/D-D/A Combination module for use with the GLOFA GM7
and MASTER-K80S series. This module is to convert an analog input signal
(voltage or current) from external sensors into a 12-bit signed Binary digital
value, and convert digital internal data to analog value (Voltage or Current)

10. ADC Characteristics (voltage input)
In voltage input, digital amount 0 is output by 0V input and 4,000 is output by 10V
input.
Therefore input 2.5mV equals to digital amount 1, but value less than 2.5mV can’t be
converted.

11. ADC Characteristics (Current input)
Current input 0mA becomes output 0, 10mA does 2000 and 20mA does 4000.
Therefore input 5 ㎂ equals to digital amount 1, but value less tan 5 ㎂ can’t be
converted. So abandon it.

12. DAC Characteristics (Voltage Output)
Input of digital amount 0 outputs analog amount 0V, 4000 does 10V. Digital input 1
equals to 2.5mV of analog amount.

13. DAC Characteristics (Current Output)
In current output, digital amount 0 exchanges to 0mA, and 4,000 does 20mA. Analog
amount of digital input 1 equals to 5 ㎂.

When the Stop switch is pressed stop button then inverter goes stop but set frequency
in last command does not reset.
Please find the below program in which Register D000 is reset by pressing T000 3S.
Think Clear !!!!
