[2] Warnings
Types of warnings
Warnings detected by the Simple Motion module include system warnings, axis
warnings and warnings detected by servo amplifier.
(1) Simple Motion module detection system warnings
The types of system warnings are shown below.

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.
(2) Simple Motion module detection axis warnings

Axis warnings occur due to setting warnings from operations such as
positioning operations, JOG operations or manual pulse generator operations.
 Axis warnings occur due to system warnings.
The axis operation status does not change even if an axis warning occurs.
(3) Servo amplifier detection warnings
These are warning that occur at the hardware error such as servo amplifier
and servomotor or the inapplicable servo parameters.
Error or normality operation can't be executed by waning when warning is left
as it is though servo off isn't executed.
When the warning cause is removed, warning is automatically released in
servo amplifier. However, the state of generating warning is continued in
Simple Motion module.
Reset it if necessary.
