If input is set to one of the built-in functions —
Home, Inhibit, Hard Stop, Soft Stop, Hard and Soft
Stop, Forward Limit, Reverse Limit or Begin —
execution is immediate upon detection: 0 < T < 4 x
TS
If input is set to General input, execution depends
on program. Typical execution time: ≅ 0.5 msec.
T < 5 μsec
Notes:
Home mode is high-speed
mode and can be used for fast
capture and precise homing.
High speed input has a digital
filter set to same value as
digital filter (EF) of main
encoder.
Highest speed is achieved
when turning on optocouplers.
