Assume that related variables are assigned values as follows. When X10 = ON, the execution result is
shown in the following gure.

Usage:
• Before the ABSD instruction is executed, use the MOV instruction to assign values to variables of the related table.
• Even if the DABSD instruction uses a high-speed instruction, the comparison result D is affected by the scan delay
of the user program. The HSZ instruction for high-speed comparison can be used for applications that require
timely response.
INCD: Incremental cam control mode
◆
Overview
When driving conditions are met, the INCD instruction compares a data table from head address S1 with
the current value of a pair of selected counters (S2) to control the ON/OFF states of K bit elements from
head address D.
