10.3.4 Turning ON the Power after Setting the Zero Point of Machine Coordinate
System
The Zero Point Return (Setting) Completed bit (IW 0C, bit 5) will turn OFF when the power supply to the Machine
Controller is turned OFF and ON or the communication is interrupted by turning OFF and ON the power supply to the
SERVOPACK after the zero point has been set. The Zero Point Return (Setting) Completed bit must therefore be
turned ON when the power supply is restored.
Use the following procedure.
1.
Turn ON the power supply to the Machine Controller.
The offset saved in the M register is stored to OL 48.
2. Check the Motion Controller Operation Ready (SVCRDY) bit.
Check to see if the Motion Controller Operation Ready (SVCRDY) bit (IW 00, bit 0) is ON.
3. Execute the Zero Point Setting (ZSET) motion command by setting OW 08 to 9.
Use this procedure only to turn ON the Zero Point Return (Setting) Completed bit (IW 0C, bit 5). It cannot be
used to set the zero point of the machine coordinate system (OL 48).
