Mask of Signal Output
The general output signals can be masked for each component.
If any of the components is judged as D, ON signal is output from the
general output which is set as “Alarm signal” of the file. This signal is
output continuously, so the signal to inform the replacement time of the
component cannot output newly. Therefore, the signal of the replacement
time for other components can be output by masking the signal output of
the component which is already judged as D and turning OFF the general
output signal temporarily.
Even if the masking is performed, D remains to be displayed for the
component judged that it should be replaced.
8.21.6.3 Replacement of Component
Record of Replacement Date of Component
When the component is replaced, the replacement date (year, month,
day) can be recorded. It can be used for the reference for the next
replacement time or for the estimation of the failure mode by the failure
time.
Life Span Setting at Replacement of Component
A new component or an used one, whichever it is replaced with, the life
span setting can be performed.
For the used component, after recording the replacement date, the value
1 - 100% can be set as the leftover life.
Display of the Numbers of Motor Revolution and Reverse Revolution
The accumulated values are displayed regarding the number of each
motor revolution and the number of reverse revolution of positive and
negative revolution. They can be used as the reference for the
replacement time of the speed reducer or motor.
