Digital Input Interfaces

Feature

Details

Type of input

Optically isolated

Input current
for all inputs

Rin=3.43K, Iin = 1.2 mA @ Vin = 5 V
Rin=3.43K, Iin = 6.7 mA @ Vin = 24 V

High-level input voltage

5 V < Vin < 24 V

Low-level input voltage

0 V < Vin < 1 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 TS
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.
