3.1 Pre-Operation Information

3.1.1 Types of operation modes

The inverter can be operated in any of "PU operation mode", "external operation mode",

"combined operation mode" and "communication operation mode". Prepare required

instruments and parts according to the operation mode. For the way of changing the

operation mode, refer to page 52.

(1) External operation mode

(factory setting Pr. 79 "operation mode selection" = 0)

Pr. 79 "operation mode selection" is factory-set to 0 and the external operation mode is

selected at power-on.

The inverter is operated using an external start signal and an external frequency setting

signal.

(2) PU operation mode (Pr. 79 "operation mode selection" = 1)

• Operation unit...................Operation panel (FR-PA02-02) or parameter unit (FR-

PU04-MGI)

• Connection cable..............To be prepared for use of the operation panel (FR-PA02

-02)

away from the inverter or for use of the parameter unit (FR-

PU04-MGI).

FR-CB2 (option)

• FR-E5P (option) ...............To be prepared for use of the operation panel away from

the inverter. It is available as a set of operation panel cover

and connection cable junction adaptor.

• Start signal .......................Switch, relay, etc.

• 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: 1. Operation cannot be started by the start signal alone. Both the start signal

and frequency setting signal are required to run the inverter.

The inverter is operated using the optional operation panel or

parameter unit.
