5.1.4 Setting the frequency by analog input (voltage input/current input)
POINT
 Use the operation panel (
 Use the potentiometer (frequency setting potentiometer) (voltage input) or 4-to-20mA input (current input) to
give a frequency command.
 Set "4" (External/PU combined operation mode 2) in Pr. 79 Operation mode selection.

Assignment of the AU signal (current input) (Refer to the step 3 for voltage input.)
Set Pr. 160 to "0" to activate extended parameters.

[RUN] indicator is lit during forward rotation operation and blinks slowly during reverse rotation operation.
Deceleration
For voltage input, turn the potentiometer (frequency setting potentiometer) counterclockwise slowly to full.

REMARKS
 For voltage input, the frequency (maximum potentiometer setting) at the full right turn of the (frequency setting) potentiometer is
60Hz in the initial setting. (To change the setting, use Pr. 125.) (Refer to page 30.)
 To input 10VDC to terminal 2, set Pr. 73 Analog input selection = "0". The initial value is "1 (0 to 5V input)" (
of the Instruction Manual (Applied.)).
 For current input, the frequency at 20mA input is 60Hz in the initial setting. (To change the setting, use Pr. 126.) (
Chapter 4 of the Instruction Manual (Applied.))
 When terminal 10 is used, the maximum output frequency may fluctuate in a range of 2 to 3Hz due to fluctuations in the output
voltage (5V  0.2VDC). Use Pr. 125 or C4 to adjust the output frequency at the maximum analog input as required. (
Chapter 4 of the Instruction Manual (Applied).)
