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.
