6.3 Error and warning of output axis
The detection processing and reset method for error and warning of output axis are similar to
normal positioning control.
Error and warning of output axis
(1) Error detection
(2) Warning detection
(3) Resetting errors and warnings

The error detection signal turns ON, and the output axis error number is stored in
" [Md.23] Axis error No.".
"b9: Axis warning detection" of " [Md.31] Status" turns ON, and the output axis warning
number is stored in " [Md.24] Axis warning No.".
Remove the cause of error or warning following the actions described in Section 6.3.1
and 6.3.2, before canceling an error or warning state through resetting the error.
An error or warning state is canceled after the following processing is carried out by
setting "1" in " [Cd.5] Axis error reset" for target axis.
• Axis error detection signal is turned OFF
• " [Md.23] Axis error No." is cleared
• " [Md.24] Axis warning No." is cleared
• Changing of " [Md.26] Axis operation status" from "Error" to "Standby".
• "Axis warning detection ( [Md.31] Status: b9)" is turned OFF
Error
• Setting value of the synchronous
parameter " [Pr.400] Main input axis No."
is outside the setting range.
• The same servo input axis No. as the
output axis is set in the synchronous
parameter " [Pr.400] Main input axis
No.".
• Setting value of the synchronous
parameter " [Pr.401] Sub input axis No."
is outside the setting range.
• The same servo input axis No. as the
output axis is set in the synchronous
parameter " [Pr.401] Sub input axis No.".
The synchronous parameter " [Pr.404]
Main shaft gear: Denominator" is set to 0
or lower.
Overflow (sign reversion) occurred in
input values, because the main shaft gear
ratio is too large.

Corrective action
• Set within the range.
• Do not set up the same servo input axis
number as the output axis.
Set a value within the range of 1 to
2147483647.
• Set a smaller absolute value for the
synchronous parameter " [Pr.403] Main
shaft gear: Numerator".
• Set a larger value for the synchronous
parameter " [Pr.404] Main shaft gear:
Denominator".
• Decrease the input axis speed.
