4.7. I/Os

The Hornet and Bee have:

• 6 Digital Inputs

• 2 Digital Outputs

• 1 Analog Input

4.7.1. Digital Input Interfaces

Feature Details

Type of input

• Optically isolated

• All six inputs share one signal return line

Input current

for all inputs

Iin = 2.4 mA @ Vin = 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 > 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<4xTS

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.
