High-speed Counter Inputs
Using IR 00000 to IR 00002 as High-speed Counter Inputs
In these examples, Encoders with an external 24-VDC open-collector output
are connected.
Note *CW is clockwise and CCW is counter-clockwise.
Using IR 00003 to IR 00006 as Interrupt Inputs (Counter Mode)
In these examples, an Encoder with an external 24-VDC open-collector out-
put is connected.
