Chapter 1 Replacement Considerations
Kinetix 350 Drives
The Kinetix 350 drive has five digital inputs. The five digital inputs
(IOD-27…IOD-30 and IOD-39) have fixed pin assignments. See
for
input assignments. Each input can be assigned an individual debounce time
via the Studio 5000 Logix Designer® application.
The inputs are separated into three groups: A, B, and C. Each group has four
inputs and share one common: IN_A_COM, IN_B_COM, and IN_C_COM,
respectively. Travel limit switches, the inhibit/enable input, and registration
input have dedicated inputs.

REG
Optically isolated, single-ended active high signal. Current

A 24V DC input is applied or removed from this terminal to
trigger registration event. Fast registration inputs are
required to ensure the motor interface can capture the
positional information with less than 5 µs uncertainty.

Overtravel detection is available as an optically isolated,
single-ended active high signal. Current loading is nominally
9 mA per input. The positive/negative limit switch (normally
closed contact) inputs for axis require 24V DC (nominal).
