Each item on the screen represents the following description.
=NG COUNT (IN A ROW)
Shows the number of the variation days, which is higher than the value of
the torque variation “HIGH”. The warning output signal, which is set by
“=ACCEPT RATE HIGH”, is turned ON when the number of the day above is
more than the number of the consecutive accept NG days.
ཱ =NG COUNT (ACCUM.)
Shows the total number of the variation days, which is higher than the
value of the torque variation “HIGH”. The number of “=NG COUNT (IN A
ROW)” is reset as “0”, when a day does not exceed the torque variation.
However, this “=NG COUNT (ACCM.)” will not be reset.
ི =MEASURED DATE
Shows the date of the measurement or the updated speed reducer
diagnosis database.
ཱི =MEAS.
Shows the measured torque average.
ུ =AVE.
Shows the arithmetic mean of the average period (certain number of the
days, which is calculated in the past, based on the MEASURED DATE).
However, the measured values excepted in the =ERROR DELETE
FILTER are not included.
ཱུ =VARIATION (The Determining Value)
Shows the difference value between the latest value and the average
value. When this value exceeds the value, which is set at the torque
variation, it is determined as accept NG.
ྲྀ =LATEST
Shows the arithmetic mean of the latest period (certain number of the
days included the measured day).
ཷ =WARNING
Select this item to invalidate the warning output signal. [Invalid] and [Valid]
will alternate each time when press the [Select].
ླྀ =RESET
Select this item after replacement of the speed reducer. The warning
output signal will be turned OFF, and the old data will not be used for the
lifetime diagnosis.
