Digital Input
Schematic
Input current
for all inputs Iin = 2.4 mA @ 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 > 360 μsec
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 the 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 the
same value as the digital filter (EF) of the main
encoder.
• Highest speed is achieved when turning on the
optocouplers.
