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<4xTS
If input is set to General input, execution
depends on program. Typical execution time: ≅
0.5 msec.
High-speed
inputs – 5 & 6
minimum pulse
width, in high-
speed mode
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
