*1 The BUSY signal, whose axis number exceeds the number of controlled axes, cannot be used.
The BUSY signal turns ON even when position control of movement amount 0 is executed. However, since
the ON time is short, the ON status may not to be detected in the program.

• When the PLC READY signal [Y0] turns from OFF to ON, the parameter setting range is
checked. If no error is found, this signal turns ON.
timer error • When the PLC READY signal [Y0] turns OFF, this signal turns OFF.
• When watch dog timer error occurs, this signal turns OFF.
• This signal is used for interlock in a program, etc.
PLC READY signal [Y0]
READY signal [X0]
• After the CPU module is turned ON or the CPU module is reset, this signal turns ON if the
disabled access from the CPU module to the Simple Motion module is possible.
• When "Asynchronous" is selected in the module synchronization setting of the CPU
enabled module, this signal can be used as interlock for the access from a program to the Simple
Motion module.
• This signal turns ON at the start of positioning, home position return or JOG operation. It
turns OFF when the "[Da.9] Dwell time/JUMP destination positioning data No." has
passed after positioning stops. (This signal remains ON during positioning.)
• This signal turns OFF when the positioning is stopped with step operation.
• During manual pulse generator operation, this signal turns ON while the "[Cd.21] Manual
pulse generator enable flag" is ON.
• This signal turns OFF at error completion or positioning stop.
