4.8. I/Os
4.8.1. Digital Input Interface – 4/6 Digital Inputs
Feature Details
Type of input Optically isolated
All inputs share one signal return line
Input current for all inputs Iin = 7.35 mA @ Vin = 24 V
Input voltage level 24 V
Note: 5 V 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.
