Functions
Analog Input Adjustment
The analog input gain can be changed. Use this function to fine-tune analog input signals.
Use "External Frequency Start/End" on page 5-40 to set for scale conversion from 0 to 10 V,
to 0 to 5 V, for example.
External Frequency Start/End
External Analog Input (Frequency Reference)
FV-SC terminal : 0 to 10 V
FI-SC terminal : 4 to 20 mA
VR : Volume on the external Digital Operator 3G3AX-OP01.
Note 1: To input current between 4 and 20 mA, set A103 to 20%. (Default value: 20% = 20 mA
×
20% = 4 mA)
Note 2: To input voltage between 0 and 5 V, set A014 to 50%.
