Starting Contact Signal
The inverter gives out the starting contact signal (FR) while it is receiving an
operational command. The FR signal is given out, regardless the setting of the run
command source setting (
). If the forward operation (FW) and reverse operation
(RV) are given at the same time, the inverter stops the motor operation.
