Description of devices
3.9.2 Inputs, Outputs X, Y
Inputs and outputs are devices designed to transfer data between the inverter and
external devices.
Inputs provide ON/OFF data given to the corresponding control input terminals from
outside the inverter. In a program, they are used as contacts (normally open, normally
closed contacts) and the source data of basic instructions. Outputs are used when the
operation results of a program are output from the control output terminals to outside
the inverter.
