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 the servo amplifier, the alarm No. displayed in the LED of the servo amplifier is stored in "[Md.114]
Servo alarm" and "[Md.115] Servo alarm detail number". Check the error details and remedies with "[Md.114] Servo alarm"
and "[Md.115] Servo alarm detail number".
Error detection signal
[Md.31] Status: b13
*1 A new error code is stored in "[Md.23] Axis error No." every time an error occurs.
The following table shows the specifications of the alarm on the drive unit.
[Md.23] Axis error No.
1ED0H
The following table shows the specifications of communication errors on the drive unit detected by the Motion module.
Error status
WDT error
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 No. is stored in "[Md.326] Synchronous encoder axis error No.".
