2.8. I/Os
The Solo Guitar Absolute Feedback has: 5 Digital Inputs
4 Digital Outputs
1 Analog Input
2.8.1. Digital Input Interfaces
Feature Details
Type of input Optically isolated
Each input has its own return
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<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.
