Error code classification
Error storage
When an error occurs, the error detection signal turns ON, and the error code corresponding to the error details is stored in
"[Md.23] Axis error No.". Note that there is a delay of up to operation cycle after the error detection signal turns ON until the
error code is stored.
When an alarm occurs on servo amplifier, the alarm No. displayed in LED of servo amplifier is stored in "[Md.114] Servo
alarm". Check the error details and remedies with "[Md.114] Servo alarm".
*1
A new error code is stored in "[Md.23] Axis error No." every time an error occurs.
When any error that is independent of an axis is detected, it is stored in the axis error No. of axis 1.
(These errors are stored in the axis error No. of axis 1 for the system which does not use the axis 1.)
For the synchronous encoder axis, "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.".
