M_PMScrEnc2: Score (encoder communication abnormality)
[Function]
Returns the score of encoder communication error of the specified axis.
[Format]
Example) <Numeric variable> = M_PMScrEnc2(<Axis number>)
[Terminology]
<Numeric variable> Specify the numeric variable to assign.
<Axis number>
When omitted, 1 is used.
[Sample]
1 M1 = M_PMScrEnc2(1)
[Explanation]
(1) Returns the score of encoder communication abnormality of each joint axis of the robot body
(mechanical 1).
(2) This variable is read only.
(3) Returns "-1" when the predictive maintenance function is disabled.
(4) Returns "0" when a nonexistent axis is specified in <Axis number>.
(5) The score value is the worst value from the time of the previous maintenance.
The worst value is retained until maintenance reset (for the encoder) of the target axis is performed.
