4.8. I/Os
The DC Trombone has:
• 6 Digital Inputs
• 4 Digital Outputs
• 1 Analog Input
4.8.1. 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.
