Item Name Function Description
FX
Forward Run /Stop
Command
RX
Reverse Run/Stop
Command
z Forward/Reverse RUN Command is ON when closed to CM in NPN
input mode.
z Motor stops when FX/RX is ON or OFF at the same time.
BX Emergency Stop
z ON when closed to CM in NPN input mode, Free-run to Stop and
deceleration to stop. It does not trigger fault alarm signal.
RST Fault Reset Resets when fault condition is cancelled.
