Analog Input Option Card
AI-14B
d) If any of the control signal input terminals (TC1-TC3) are NOT used, jumper them to the 0V terminal (TC4).
e) Route wires from the drive and connect to the peripheral device. Refer to the drive technical manual for further
information on use of shielded cable.
f)
Important:
Because the analog input is high-resolution, the voltage source accuracy of the analog input must be
considered. To ensure accuracy, use a high-precision power supply for the voltage source.

Adjustment
. There are no adjustments to be made on the AI-14B option; however, the drive will have to be programmed
for the input requirements of the peripheral device and the reversing or non-reversing requirement of the specific
application. Refer to Figures 4 and 5, and Table 3.
8. Reinstall and secure the drive’s front cover.
9. Place this instruction sheet with the drive’s technical manual.
