Offset/Gain Setting Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Offset/gain Setting Function

This function sets any analog value to the offset/gain value without regard to the setting prepared in advance as the analog
output range. The offset setting value and gain setting value are saved in the built-in memory of the FX5-4DA-ADP.
For changing the offset/gain data, set an analog value to the "offset setting value" or "gain setting value".
The table below shows the available setting range.

Gain setting value
An offset/Gain setting value range error occurs when the following condition is not satisfied: (Error code:
1B9H)
• Voltage output: 1000Gain setting value-Offset setting value10000
• Current output: 3000Gain setting value-Offset setting value30000
The table below shows the reference value and initial value of the offset/gain setting value.
