F unct i on
(1) When the execution command is ON, the following processing is executed.
• Shifts from the value specified for n1 to the value specified for n2 in the number of times
specified for n3.
• For n3, specify the number of scans (number of shifts) required for shift from n1 to n2.
No processing is performed when n3 = 0.
• The system uses [1] to store the number of times the instruction has been executed.
• The value of one variation (one scan) is obtained by the expression below.
RAMP
indicates the following instruction.
