High-level input

voltage

Low-level input

voltage

0 V < Vin < 6.5 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 < T < 4 x T
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.
