(The value automatically turns to "0" after 
completion of a counter reset.) 
Set "1" in the "counter reset 
request" of the buffer memory to 
reset the accumulating count 
value. (This error is cleared when 
the error reset request (Y8 to YF) 
turns ON but requires the counter 
to be reset to perform count 
operation.)
