Setting the Interrupt Input to Use
A specified combination of pulse output and interrupt input must be used for the IFEED(892) instruc-
tion. You cannot change the combinations. The pulse output and interrupt input are specified with
operand P (port specifier) of the IFEED(892) instruction.

Precautions for Correct Use Precautions for Correct Use
• Before executing the IFEED(892) instruction, use the MSKS(690) instruction to disable the
specified interrupt if it is currently not masked. An instruction error will occur if the IFEED(892)
instruction is executed when the interrupt is not masked.
• Interrupt inputs 0, 1, 4, and 5 are used with the IFEED(892) instruction. The terminals used for
interrupt inputs 0 and 1 are also used for the origin and origin proximity inputs for pulse output
0. The terminals used for interrupt inputs 4 and 5 are also used for the origin and origin prox-
imity inputs for pulse output 2. If the IFEED(892) instruction is used for pulse output 0 or 2, do
not use the origin search function.
