Digital Input
Schematic
Input current
for all inputs
Iin = 2.4 mA @ Vin = 5 V
High-level
input voltage
2.5 V < Vin < 10 V, 5 V typical
Low-level
input voltage
0 V < Vin < 1 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: 0If 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.
The Default Digital Input Level is 5 V. 24 V Level is also available.
