4.8.3.5 X9, X10, X11, X12 Inputs with common COM Port
The SV200 drives also have 4 single ended optically isolated inputs connected with a single common node named ‘COM’. These inputs
can be used with sourcing or sinking signals, 12-24V. This allows for connection to PLCs, sensors, relays and mechanical switches.
Because the input circuits are isolated, they require a source of power. If you are connecting to a PLC, you should be able to get power
from the PLC power supply. If you are using relays or mechanical switches, you will need a 12-24V power supply.
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. If you are using sinking (NPN) signals, then COM must connect to the power . If you are using
sourcing (PNP) input signals, then you will want to connect COM to ground (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.
