• A connection diagram of the emergency drive (commercial mode) is as follows.
Emergency drive execution
*1
Be careful of the capacity of the sequence output terminals.
The applied terminals differ by the settings of Pr.190 to Pr.196 (Output terminal function selection).
Output terminal capacity
Open collector output of inverter
(RUN, SU, IPF, OL, FU)

When connecting a DC power supply, insert a protective diode.
When connecting an AC power supply, use relay output terminals of the inverter or contact output terminals of the relay output option
(FR-A8AR).
*3
The applied terminals differ by the settings of Pr.180 to Pr.189 (Input terminal function selection)
*4
The applied terminals differ by the settings of Pr.190 to Pr.196 (Output terminal function selection).
