Frequency setting by analog input (terminals 1, 2 and 4)
Perform operation by analog input voltage
The frequency setting signal inputs 0 to 5V DC (or 0 to 10V DC) to across the terminals 2-5. The
5V (10V) input is the maximum output frequency. The maximum output frequency is reached
when 5V (10V) is input.
The power supply 5V (10V) can be input by either using the internal power supply or preparing
an external power supply. The internal power supply outputs 5V DC across terminals 10-5, or
10V across terminals 10E-5.
