Basic operation procedure (PU operation)
Setting the frequency with analog signals (voltage input)
Use the operation panel (FR-DU08) (FWD or REV key) to give a start command.
Use the potentiometer (frequency setting potentiometer) to give a frequency command (by con-
necting it across terminals 2 and 5 (voltage input)).
Set Pr. 79 "Operation mode selection" = "4" (External/PU combination operation mode 2).
(The inverter supplies 5 V power to the frequency setting potentiometer (terminal 10).)
Operation example: Operate at 60 Hz.

Changing the operation mode
Set "4" in Pr. 79. [PU] and [EXT] indicators are lit. (For setting value change, refer to page 4-6.)
Acceleration ➔ constant speed
Turn the potentiometer (frequency setting potentiometer) clockwise slowly to full. The frequency value on the
indication increases in Pr. 7 "Acceleration time", and "
Turn the potentiometer (frequency setting potentiometer) counterclockwise slowly to full. The frequency value on the
indication decreases in Pr. 8 "Deceleration time", and the motor stops rotating with "
