High-level input
voltage
12 V < Vin < 30 V, 24 V typical
Low-level input
voltage
0 V < Vin < 6.5 V
Minimum pulse width > 4 x TS, where TS is sampling time
I/O inputs PLC level only
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 < 4 x
TS
If input is set to General input, execution depends
on program. Typical execution time: ≅ 0.5 msec.
High-speed inputs -
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.
