Mitsubishi FR - S500 instruction manual Voltage input 10, 2, Basic

1.7.2 Connection of frequency setting potentiometer and output frequency meter (10, 2, 5, 4, AU)

The analog frequency setting input signals that may be entered are voltage and current signals.

For the relationships between the frequency setting input voltages (currents) and output frequencies, refer to the following diagram. The frequency setting input signals are proportional to the output frequencies. Note that when the input signal is less than the starting frequency, the output frequency of the inverter is 0Hz.

If the input signal of 5VDC (or 10V, 20mA) or higher is entered, the output frequency does not exceed the maximum output frequency.

Relationships between Frequency Setting Inputs and Output Frequencies

	REMARKS
	For the way to calibrate the output frequency meter, refer to the instruction manual						1
	(basic).
(1) Voltage input (10, 2, 5)
Enter the frequency setting input signal of 0 to 5VDC (or 0 to 10VDC) across the
frequency setting input terminals 2-5. The maximum output frequency is reached
when 5V (10V) is input across terminals 2-5.
The power supply used may either be the inverter's built-in power supply or an
external power supply. For the built-in power supply, terminals 10-5 provide 5VDC
output.
