Mitsumi electronic FR-F520-0.75K, 55K Devices and parts to be prepared for operation

3.1 Pre-Operation Information

OPERATION/CONTROL

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				Inverter
operation signals	(frequency	setting	potentiometer,	DU04
start switch, etc.)	connected	to the	terminal block.
				PU04
With input power on, switch on the start signal (STF,
STR) to start operation.
Preparation				Start switch
• Start signal		Switch, relay, etc.		Potentiometer

•Frequency setting signal ..............0 to 5V, 0 to 10V or 4 to 20mA DC signals or multiple speeds from a potentiometer or outside the inverter

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

DU04

PU04

•	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.
		FR-CB2 (option) or the following connector and cable available on the
		market:
		Connector: RJ45 connector
		Cable	: Cable conforming to EIA568 (e.g. 10BASE-T cable)

(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.
