Warning type

Warnings detected by the Simple Motion module include system warnings, axis warnings and warnings detected by servo
amplifier.
Simple Motion module detection system warnings
• System control data setting warnings: An axis warning for axis 1 will occur.
• Positioning data setting warnings: An axis warning for each axis will occur. Note that a warning will occur for the reference
axis when an interpolation designation or axis setting warning occurs.
Simple Motion module detection axis warnings
• Axis warnings that occur at operation start or during operation such as the positioning operation, JOG operation or manual
pulse generator operation.
• Axis warnings that occur due to system warnings: The axis operation status does not change even though an axis warning
occurs.
Servo amplifier detection warnings
The warnings that occur when the hardware error of the servo amplifier or servo motor occurs or the servo parameter is
inapplicable.
The servo may not be turned off depending on the warning. However, an error occurs or the operation cannot be executed
normally if the warning is remained.
When the warning cause is removed, the warning is automatically released in the servo amplifier. However, the state that the
warning occurs is continued in the Simple Motion module.
Reset it as necessary.

Warning storage

When an axis warning occurs, the warning code corresponding to the warning details is stored in "[Md.24] Axis warning No.".
When an axis warning occurs in a positioning operation, etc., axis warning detection ([Md.31] Status: b9) for axis status
storage turns ON.
When a warning occurs on servo amplifier, the warning No. displayed in LED of servo amplifier is stored in "[Md.114] Servo
alarm". Check the warning details and remedies with "[Md.114] Servo alarm".
Warning detection signal
[Md.31] Status: b9
*1 A new warning code is stored in "[Md.24] Axis warning No." every time a warning occurs.
For the synchronous encoder axis, "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.".
