OPERATION/CONTROL
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
