(1) When the "Frequency setting" contact is turned ON, the frequency reference data that is set in
D00000 is forwarded to the remote I/O output relay area (word n + 1).
(2) When the "Forward" contact is turned ON, "Forward/stop (word n bit 0)" of the remote I/O output
relay area turns ON and forward operation starts. During forward operation, "During forward
operation (word m bit 0)" of the remote I/O input relay area turns ON.
(3) When the "Forward" contact is turned OFF and after decelerating and stopping, "During forward
operation (word m bit 1)" of the remote I/O input relay area turns OFF.
(4) When the "Reverse" contact is turned ON, "Reverse/stop (word n bit 1)" of the remote I/O output
relay area turns ON and reverse operation starts. During reverse operation, "During reverse
operation (word m bit 1)" of the remote I/O input relay area turns ON.
(5) When the "Reverse" contact is turned OFF and after decelerating and stopping, "During reverse
operation (word m bit 1)" of the remote I/O input relay area turns OFF.
(6) When "Fault (word m bit 3)" of the remote I/O input relay area turns ON, "Fault occurred" turns ON.
(7) When the "Fault reset" contact is turned ON, "Fault reset (word n bit 7)" of the remote I/O output
relay area turns ON and the fault is cancelled.
