Delta AS Series Programming Manual page 784

When the counter type is linear, the value in Comp 1 and Comp 2 should satisfy the following condition: the smallest
8.
counter value < Comp < the largest counter value. If you are using SSI (serial synchronous interface) encoder and
the setting of counter mode is in Absolute Position. The value in Comp 1 and Comp 2 should satisfy the following
condition: 0< Comp<2 (MT+ST Length)
9. The timing to be considered reaching the set value varies according to different settings on input interfaces in
HWCONFIG, for example pulse input and SSI input.
Ex. Comp = 5
Comp

Counted Value
0 1
Pulse Input -
Timing to consider as reaching the target
SSI Input -
Timing to consider as reaching the target
If the input interface is pulse input, the timing to be considered to meet the set value is before the counting leaving
the set value. Take Comp = 5 as an example, when the counting goes from 5 to 6 or from 5 to 4, the timing here is
considered the set value reached.
If the input interface is SSI input, the timing to be considered reaching the set value is right before the counting
touching the set value. Take Comp = 5 as an example, when the counting goes from 4 to 5 or from 6 to 5, the timing
here is considered the set value reached.
10. If the counter value of ChNo met the set value, its corresponding flag Match 1 / Match2 will be ON. The appointed
output point by Yno1 and Yno2 reacts according to the settings for Actions: Action 1 (for the appointed output point
by Yno1) and Action 2 (for the appointed output point by Yno2).
