• Start signal.................................. Switch, relay, etc. (for 1)
• Frequency setting signal............. 0 to 5V, 0 to 10V or 4 to 20mA DC signals from a potentiometer or
outside the inverter (for 2)
• 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) Combined operation mode

(4) Communication operation mode
Communication operation can be performed by connecting a personal computer and the PU connector with
the RS-485 communication cable.
