(1) Linear accumulation:
If an accumulation register counts up, it counts from 0 to 999999999. If an accumulation
register counts down, it counts from 0 to -999999999.
If the value in an accumulation register is larger than the maximum value 999999999 or less
than the minimum value -999999999, the value in the accumulation register will be
999999999 or -999999999, and bit 1 in CR19/CR47/CR75/CR103 will be turned ON. Users
can read the error code 16#A0n1 in CR26/CR54/CR82/CR110. (n is a channel number. n:
0~3 (i.e. channel 0~channel 3))

If the linear accumulation is larger than the maximum value 999999999 or less than the
minimum value -999999999 in the count cycle, the value stored in the accumulation register
will be 999999999 or -999999999, bit 1 in CR19/CR47/CR75/CR103 will be turned ON.
Users can read the error code 16#A0n1 in CR26/CR54/CR82/CR110. (n is a channel
number. n: 0~3 (i.e. channel 0~channel 3)) If bit 1 in CR0/CR28/CR56/CR84 is turned ON,
the sampling register/accumulation register/pulse input register, and bit 1 in
CR19/CR47/CR75/CR103 will be reset. After the sampling register/accumulation
register/pulse input register, and bit 1 in CR19/CR47/CR75/CR103 is reset, bit 1 in
CR0/CR28/CR56/CR84 will be turned OFF automatically.
