6.35.3 Calibration of analog outputs
H : FM voltage/current output switching
H , H : FM output gradient characteristic and bias adjustment
H , H : AM output gradient characteristic and bias adjustment
•Function
Output signals from FM/AM terminals are analog voltage signals. Their standard setting range is from 0 to
10Vdc.
The output current from terminal FM can be changed to 0 to 20mAdc (or 4 to 20mAdc) by changing the settings
of terminal SW2 and a parameter.

+ The analog output inclination can be adjusted using the parameter HO
+ For code data 50 to 64, negative inclination is invalid.
