Chapter 3 Kinetix 7000 Connector Data
Analog Inputs (IOD Connector)
Two analog inputs are provided, with 14-bit resolution (13 data bits, plus sign).
The analog data streamed to RSLogix by these inputs is useful for managing
dynamic machine operations, for example tension transducers in an outer tension
control loop.
The input range of these inputs is ±10V, and overvoltage protection is ±12V.
Inputs are updated at the drive every 125 μs. Frequency response of the input is
up to 4 kHz, and input impedance is 12 kΩ.
Analog inputs are available as a real time attribute and Get System Value (GSV)
within RSLogix software.
The schematic below depicts the Analog Input circuits. It is provided as a
reference only.

RSLogix 5000 software, version 15, does not support analog input
utilization.
ATTENTION: Gain and offset attributes are not provided for the Analog Inputs
input signals, and no drive faults are issued.
