( 4 ) Turning ON the Power for a Finite Length Axis
The Zero Point Return (Setting) Completed bit (IB
0C5) will turn OFF when the power supply to
the MP2300 is turned OFF and ON, the communication are interrupted by the power OFF to the
SERVOPACK, or communication are interrupted in any other reason after the zero point has been
set. The Zero Point Return (Setting) Completed bit must therefore be turned back ON when the
power supply is restored.
Use the following procedure.
1. Turn ON the power supply to the MP2300 (or clear alarms to restart communication).
2. Confirm that communication have been synchronized by checking to see if the Motion
Controller RUN Ready bit (SVCRDY) (IB
000) is ON.
3. Set the Zero Point Offset (OL
48) to the same value as it was the last time the zero
point was set. This will establish a machine coordinate system for the MP2300.
4. Execute the Zero Point Setting (ZSET) motion command by setting OW
08 to 9.
This is done only to turn ON the Zero Point Return (Setting) Completed bit
(IB
0C5). It will not cause the coordinate system to be reset by executing the ZSET
command.
