*1. The BUSY signal, whose axis No. exceeds the number of controlled axes, cannot be used.
POINT
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.
• 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 access
from the CPU module to the simple motion module is
possible.
• When "Asynchronous" is selected in the module
synchronization setting of the CPU 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.
