Digital Input Interfaces
Feature
Details
Type of input
•
Optically isolated
•
All four inputs share one signal return line
Input current for 5 V DI level
R
in
=1.43K, I
in
= 2.8 mA @ V
in
= 5 V
Input current for 24 V DI level
R
in
=10.52k, I
in
= 2.2 mA @ V
in
= 24 V
High-level input voltage
5 V < V
in
< 24 V
Low-level input voltage
0 V < V
in
< 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: 0
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.
