3.3.3 X3/X4/X5/X6 Digital Input
While the STEP and DIR inputs are designed for high-speed digital input operation, the X3/X4/
X5/X6 input are designed for low speed digital input operation between 5 and 24 volts optically
Isolated Single-ended input.
What is COM?
“Common” is an electronics term for an electrical connection to a common voltage. Sometimes
“common” means the same thing as “ground”, but not always. In the case of the TSM17 drives, if
you are using sourcing (PNP) input signals, then you will want to connect COM to ground (power
supply -). If you are using sinking (NPN) signals, then COM must connect to power supply +.
Note: If current is flowing into or out of an input, the logic state of that input is low or
closed. If no current is flowing, or the input is not connected, the logic state is high or
open.
The diagrams below show how to connect X3/X4/X5/X6 input to various commonly used devices.
