Function and operation explanation
• The rotating speed (rpm) or present angle of the resolver connected to
the F2-32RM type programmable cam switch is read out to the PLC.
Whether the rotating speed or the present angle is determined by the
setting switch #4 of F
2-32RM, whether OFF or ON.
• The content of the device specified by , is determined by the
connection position of FX
2-24EI type special adapter.
• In the device specified by , the data of the rotating speed or the
present angle being read out is stored.
