Operation
■
1.When the Frequency Reference Input Bit turns ON, the rotational speed reference data specified
in D00000 is moved to remote I/O output word n + 1.
2.When the Forward Input Bit turns ON, remote I/O word n bit 0 (Forward/Stop) will turn ON, and
forward operation will start. During forward operation, remote I/O word m bit 2 (During Forward
Run) will be ON.
3.When the Forward Input Bit turns OFF, remote I/O word m bit 2 (During Forward Run) will turn OFF
after operation will decelerate to a stop.
4.When the Reverse Input Bit turns ON, remote I/O word n bit 1 (Reverse/Stop) will turn ON, and
reverse operation will start. During reverse operation, remote I/O word m bit 3 (During Reverse
Run) will be ON.
5.When the Reverse Input Bit turns OFF, remote I/O word m bit 3 (During Reverse Run) will turn
OFF after operation decelerates to a stop.
6.When the remote I/O Fault Bit (word m bit 0) turns ON, the Fault Flag will turn ON.
7.When the Fault Reset Input Bit turns ON, remote I/O word n bit 2 (Fault Reset Input Bit) will turn
ON, and the fault will be cleared. When the fault is reset, the Fault Flag will turn OFF simultaneous-
ly.
