Kinetix 350 Drive Connector Data
Chapter 3
Control Signal Specifications
This section provides a description of the Kinetix 350 drive I/O (IOD),
communication, shunt resistor and DC bus (BC), and back-up power (BP)
connectors.
Digital Inputs
Five fixed inputs are available for the machine interface on the Kinetic 350
drive.
The five digital inputs (IOD-27…IOD-30 and IOD-39) have fixed pin
assignments.

IMPORTANT
To improve registration input EMC performance, refer to the System Design
for Control of Electrical Noise Reference Manual, publication
.
IMPORTANT
Over-travel limit input devices must be normally closed.

ENABLE
Optically isolated, single-ended active high signal. Current loading is nominally 9 mA. A 24V
DC input is applied to this terminal to enable the axis.

IOD-30
HOME
Optically isolated, single-ended active high signal. Current loading is nominally 9 mA. Home
switch (normally open contact) inputs axis require 24V DC (nominal).

IOD-39
REG
Optically isolated, single-ended active high signal. Current loading is nominally 9 mA.
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).
