NSK EDD Megatorque Motor - Function of Control Input

8. More Advanced Function
— 8-2 —
8.1.1. Function of Control Input
 You may set function, port polarity and filter to each control input port. This function permits you to
change the preset input port function to other function, or to switch to one of extended functions.
 When you assign the same function to multiple input ports, the logical addition of each input
shall be the input to the Driver Unit.
(If one of the ports is activated, its function becomes effective.)
 When setting an input function that is not included in the shipping set, you must interchange it
with a preset function. For example, you may set it to one of the inputs of PRG0 to PRG7 if you
do not use all of 256 program channels.
