(a) This signal notifies the simple motion module that
the CPU module is normal.
• It is turned ON/OFF with the program.
(b) When the data (parameter, etc.) are changed, this
signal is turned OFF depending on the parameter.
(c)The following processes are carried out when this
signal turns from OFF to ON.
• The parameter setting range is checked.
• The READY signal [X0] turns ON.
(d) The following processes are carried out when this
signal turns from ON to OFF. In these cases, the
OFF time should be set to 100 ms or more.
• The READY signal [X0] turns OFF.
• The operating axis stops.
• The M code ON signal ([Md.31] Status: b12) for
each axis turns OFF, and "0" is stored in
"[Md.25] Valid M code".
(e) When parameters or positioning data (No.1 to 600)
are written from the GX Works3 or CPU module to
the flash ROM, this signal will turn OFF.
• All the servo amplifiers connected to the simple
motion module are turned ON or OFF.
• Home position return operation or positioning
operation is started.
• The positioning start signal is valid at the rising edge,
and the operation is started.
• When this signal turns ON during BUSY, the warning
"Start during operation" (warning code: 0900H) will
occur.
