7.2.5 Functions of AH02HC-5A/AH04HC-5A
Function Description
Enabling/Disabling a count
1. Users can enable or disable a channel.
2. If unnecessary channels are disabled, the internal
operation will become more efficient.
Accumulation
counter
Linear count
The number of accumulated pulses is in the range of
-999999999 to 999999999. If the number of accumulated
pulses is not within the range, the overflow flag will be
turned ON.
Circular
count
The number of accumulated pulses is in the range of
-999999999 to 0, or in the range of 0 to 999999999.
Comparison
If the number of accumulated pulses meets the comparison
condition set, the comparison flag will be turned ON, and a
signal will be output. Users can reset the comparison
condition.
Sampling
counter
Setting a
cycle
Users can change the cycle of updating the number of
sampled pulses or the cycle of updating the number of
accumulated pulses.
Averaging
the number
of sampled
pulses
The number of sampled pulses is divided by the number of
cycles set by users.
Prescaling
The number of input pulses is multiplied by a scale.
