Replacement time display
• Stepwise display of replacement time
For each component, a judgment from A to D is displayed, and it can be used as the
reference for the replacement time.
• Signal output of replacement time
If any of the components is judged as D, ON signal is output from the general purpose
output which is set as „Alarm signal“ of the file.
However, only one signal for this general purpose signal can be output for one controller.
•
Mask of signal output
The general purpose output signals can be masked for each component.
If any of the components is judged as D, ON signal is output from the general purpose
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 purpose
output signal temporarily.
Even if the masking is performed, D remains to be displayed for the component judged that
it should be replaced.
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.
Judgment display Status
A New - Used about half of its life span
B Used about half of its life span
C Used about half of its life span - Time to replace (reference)
D Time to replace (reference)
