Digital Input Interfaces
Feature
Details
Type of input
•
Optically isolated
•
All six inputs share one signal return line
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: 0
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.
