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)
O2-L terminal: -10 to 10 V (voltage input)
Also set an output frequency for the FREQ adjuster on the Digital Operator.
Adjusting the O2-L and OI-L Terminals
•To input voltage ranging from 0 to 5 V on the OI-L terminal, set A014 to 50%.
