(b) Error search output axis No. storage register (D808+10n) ..... Data from SCPU
to PCPU
1) This register is designed to store the axis number of the output module in
error which was detected by the error search function in the virtual mode.
2) If there are no errors at the virtual servo motor axes of the main shaft and
auxiliary input axis, the error occurrence output axis No. is stored into the
error search output axis No. storage register of the corresponding drive
module No. when a minor or major error occurs at the connected output axis.
3) Error search and error reset
a) Searching the main shaft for error
The output axes connected to the main shaft are searched for an error in
order of lower to higher numbers. If either a minor or major error has
occurred, the corresponding output axis No. is stored into the error search
output axis No. storage register.
Resetting the error of the corresponding output axis stores the other error
occurrence output axis No. connected to the same main shaft.
b) Searching the auxiliary input axis for error
If either a minor or major error has occurred at the output axis connected
to the auxiliary input axis, the corresponding output axis No. is stored into
the error search output axis No. storage register.
However, when the differential gear (for virtual main shaft connection) is
used to provide auxiliary input to the main shaft, the output axis connected
to the auxiliary input axis is not searched for an error. Use the main shaft
side error search output axis No. storage register to confirm the error
occurrence output axis No.
4) When error occurs at the drive module axis
When an error occurs at the main shaft/auxiliary input axis to which the output
axis is connected, "0" (no error) is stored into the error search output axis No.
storage device if an error occurred at the output axis.
