IntroductionThe G7F-ADHA is A/D-D/A Combination module for use with the GLOFA GM7and MASTER-K80S series. This module is to convert an analog input signal(voltage or current) from external sensors into a 12-bit signed Binary digitalvalue, and convert digital internal data to analog value (Voltage or Current)

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

ADDITIONAL
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 !!!!
????? QUESTIONS ?????
ADDITIONAL
1. Why G7F-ADHA is 12 bit?2. Why D4983 max value 4000?3. How can we got analog output from Inverter?4. How to interface Inverter output to PLC?5. How to Program PLC for Analog Input?
What is sol…. !!!!
