3.1 Pre-Operation Information

3.1.1

Devices and parts to be prepared for operation

The inverter can be operated in any of the "external operation mode", "PU operation mode", "combined
operation mode" and "communication operation mode". Prepare required instruments and parts according to
the operation mode.
(1) External operation mode (factory setting)
The inverter is operated under the control of external
operation signals (frequency setting potentiometer, start
switch, etc.) connected to the terminal block. With input
power on, switch on the start signal (STF, STR) to start
operation.
Preparation
• Start signal.................................. Switch, relay, etc.
• Frequency setting signal............. 0 to 5V, 0 to 10V or 4 to 20mADC signals or multiple speeds from a
Note: Both the start signal and frequency setting signal are required to run the inverter.
(2) PU operation mode
The inverter is operated from the keypad of the PU
(FR-DU04/FR-PU04).
This mode does not require the operation signals to
be connected and is useful for an immediate start of
operation.
Preparation
• Operation unit ............................. Operation panel (FR-DU04), parameter unit (FR-PU04)
• Connection cable........................ To be prepared for use of the operation unit away from the inverter.
(3) External/PU combined operation mode
The inverter is operated with the external operation and
PU operation modes combined in any of the following
ways:
1) The start signal is set with the external signal and the
frequency setting signal set from the PU.
2) The start signal is set with the run command key of
the PU (FR-DU04/FR-PU04) and the frequency
setting signal set with the external frequency setting
potentiometer.
