High-level input
voltage 12 V < Vin < 30 V, 24 V typical
Low-level input
voltage 0 V < Vin < 6.5 V
Minimum pulse
width > 4 x TS, where TS is sampling time
Execution time
(all inputs):
the time from
application of
voltage on input
until execution
is complete 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.
