High-level input

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.
