[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
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, warning is automatically released in the
servo amplifier. However, the state that the warning occurs is continued in the
Simple Motion module.
Reset it if necessary.
