Signal name Details
Y0 PLC READY OFF: PLC READY OFF
ON: PLC READY ON
(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. (Page 542 Memory Configuration and Data Process)
(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 engineering tool
or CPU module to the flash ROM, this signal will turn OFF.
Y1 All axis servo ON OFF: Servo OFF
ON: Servo ON
• The servo for all the servo amplifiers connected to the Simple Motion module is 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.
