Origin return is performed according to the speed command value set in the
Axis Operating Output Memory Areas and started when the ORIGIN
RETURN Bit turns ON.
Execute ORIGIN RETURN when the Busy Flag for the corresponding axis is
OFF. If ORIGIN RETURN is executed while the axis's Busy Flag is ON, a Mul-
tistart Error (axis error code: 3050) will occur and ORIGIN RETURN will not
be executed. When starting ORIGIN RETURN, make sure that the ORIGIN
RETURN Bit will remain ON until the Busy Flag turns ON.
If the SERVO UNLOCK, DEVIATION COUNTER RESET, EMERGENCY
STOP, OR DECELERATION STOP command bit is turned ON, the ORIGIN
RETURN command will be ignored. Be sure that all of these command bits
are OFF before executing an origin return.
The target speed for an origin return operation can be changed while ORIGIN
RETURN is being executed by setting the new speed command value in the
Axis Operating Output Memory Area. (For details on changing the target
speed, which is the same as positioning operations, refer to
9-4-4 Changing
Target Speed
.)
Torque limit during operation is possible with origin return operations. For fur-
ther details on the torque limit function, refer to
10-4 Torque Limits
.
