The ON/OFF timing and conditions of the input signals are shown below.
ON: READY
• When the PLC READY signal [Y0] turns from OFF to ON, the parameter setting
OFF: Not READY/
range is checked. If no error is found, this signal turns ON.
Watch dog
• When the PLC READY signal [Y0] turns OFF, this signal turns OFF.
timer error
• When watch dog timer error occurs, this signal turns OFF.
• This signal is used for interlock in a PLC program, etc.
OFF: Module
• After the PLC is turned ON or the CPU module is reset, this signal turns ON if the

• With using continuous path control for the positioning operation, the positioning will
continue even when this signal does not turn OFF. However, a warning will occur.

• When the PLC READY signal [Y0] turns OFF, the M code ON signal will also turn
OFF.
• If operation is started while the M code is ON, an error will occur.
OFF: No error • This signal turns ON when an error listed in Section 15.1 occurs, and turns OFF
