When driving three or more motors, use the plug-in option (FR-A8AR).
Always provide mechanical interlocks for the MC.
The applied output signal terminals differ by the settings of Pr. 190 to Pr. 196 (output terminal
function selection).
The applied input signal terminals differ by the settings of Pr. 178 to Pr. 189 (input terminal function
selection).
"
The applied output signal terminals differ by the settings of Pr. 320 to Pr. 322 (RA output selection).
!
There is no need to input AU signal.
Prepare the commercial power supply in accordance with the power supply specifications of the
detector.
