Built-in Inputs
Section 6-1
Restrictions on Quick-response Inputs
• Quick-response inputs 0 to 3 cannot be used when built-in inputs IN0 to
IN3 are being used as general-purpose inputs or high-speed counter
inputs.
• Quick-response input 3 cannot be used when high-speed counter input 0
is being used.
Quick-response input 2 cannot be used when high-speed counter input 1
is being used.
• Quick-response inputs 0 and 1 cannot be used when the origin search
function is enabled for pulse output 0 (enabled in the PLC Setup).
Quick-response inputs 2 and 3 cannot be used when the origin search
function is enabled for pulse output 1 (enabled in the PLC Setup).
