High-level input voltage 12 V < V
in
< 30 V, 24 V typical
Low-level input voltage 0 V < V
in
< 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.
High-speed inputs - minimum
pulse width, in high-speed mode
(IN5 - IN6)
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.
