Functions
External Frequency (Voltage/Current) Adjustment
External Analog Input (Frequency Reference)
O-L terminal: 0 to 10 V (voltage input)
OI-L terminal: 4 to 20 mA (current input)
Also set an output frequency for the FREQ adjuster on the Digital Operator.
•To input voltage ranging from 0 to 5 V on the O-L terminal, set A014 to 50%.
O/OI Adjustment
•You can adjust the O/OI frequency input.
•Use this to change the full scale of input.
•The set frequency becomes 0 Hz with 0.0% set.
