(2) Error search output axis No. storage register (D1128+10n)
..................... Monitor device
(a) This register stores the axis No. of the output module in error by the error
search function in the virtual mode.
(b) If there are no errors at the synchronous encoder 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.
(c) Error search and error reset
1) 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.
2) 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.
(d) 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.
