• The signal changes only when Element 2 of the PMRPTSCR parameter is "1"
(output).
• If the predictive maintenance function is disabled, the output is always OFF.
• For parts for each joint axis, if even one of the axes exceeds the warning
occurrence detection level, the signal becomes ON.
Function
−
Maintenance warning of
(reduction gear abnormality detection)
Outputs the effect that the score of the reduction
gear exceeded the detection level.
* The detection level is specified by the
PMWNGDRV parameter.
−
Maintenance warning of
(encoder data abnormality detection)
Outputs the effect that the score of the encoder data
abnormality exceeded the detection level.
* The detection level is specified by the
PMWNGEN1 parameter.
−
Maintenance warning of
(encoder communication abnormality detection)
Outputs the effect that the score of the encoder
communication abnormality exceeded the detection
level.
* The detection level is specified by the
PMWNGEN2 parameter.
Function
Status information reset of the abnormality detection
of predictive maintenance.(encoder)
Resets the abnormality detection status information
of the encoder.
* The axis bit pattern is specified by the IODATA or
DIODATA parameter.
Outputs the reset completion.
