6.2 Error and warning of input axis

The detection processing and reset method for error and warning of input axis are different in
the servo input axis and synchronous encoder axis.
Error and warning of servo input axis
(1) Error detection
(2) Warning detection
(3) Resetting errors and warnings
Error and warning of synchronous encoder axis
(1) Error detection
(2) Warning detection
(3) Resetting errors and warnings
The error detection signal for target axis turns ON, and the input axis error number is
stored in " [Md.23] Axis error No.".
"b9: Axis warning detection" of " [Md.31] Status" turns ON, and the input axis warning
number is stored in " [Md.24] Axis warning No.".
Remove the cause of error or warning following the actions described in Section 6.2.1
and 6.2.2, 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
"b4: Error detection flag" of " [Md.325] Synchronous encoder axis status" for target axis
turns ON, and the input axis error number is stored in " [Md.326] Synchronous encoder
axis error No.".
"b5: Warning detection flag" of " [Md.325] Synchronous encoder axis status" for target
axis turns ON, and the input axis warning number is stored in " [Md.327] Synchronous
encoder axis warning No.".
Remove the cause of error or warning following the actions described in Section 6.2.1
and 6.2.2, 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.323] Synchronous encoder axis error reset" for target axis.
• " b4: Error detection flag" of " [Md.325] Synchronous encoder axis status" is turned
OFF.
• " [Md.326] Synchronous encoder axis error No." is cleared.
• " b5: Warning detection flag" of " [Md.325] Synchronous encoder axis status" is
turned OFF.
• " [Md.327] Synchronous encoder axis warning No." is cleared.
