Chapter 9 Inverter Functions
9-12-3
9.12.3 Outputting a Signal When RUN Command Is Given
 How to detect that the inverter has received RUN commands and inform the system?
 Assigning "RUN command active [FR] (41)" to one of the output terminal functions
([C021]/[C022]/[C026]) enables the inverter to output a RUN command active signal.
 The [FR] signal is output while the inverter is receiving a RUN command.
 The [FR] output signal is output based on the RUN command reception status, even if the RUN
command input source is not the [FW]/[RV] input terminals.
 When the RUN command signal is assigned to an input terminal, if "Forward rotation [FW](00)"
and "Reverse rotation [RV](01)" RUN commands are received from the input terminal
simultaneously, a stop command will be issued as a result of the command inconsistency. In this
case, "RUN command active [FR] (41)" is not output.
 The [FR] signal is output even when the DC voltage is being output from the inverter to the
motor due to DC braking or other reasons.
