A-13
A.7 I/Os
A.7.1 Digital Input Interface – 6 Digital Inputs
Feature Details Connector Location
Type of input
 Optically isolated
 All six inputs share one signal return line
Input current
for all inputs
Iin = 6.5 mA @ Vin = 24 V
Input voltage
level
24 V
Note: 5V level is also available
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.
