Isolated Analog Input Option Card
AI-040
Part Number: AI-040 Kit (UTC000015 Card) (formerly AI-14B2). 
 
Applicability: F7, G7, GPD515/G5. 
Note: If used in a GPD503/G3, refer to Instruction Sheet 
02Y00025-0431. 
 
Introduction: The AI-040 isolated analog input option board is 
mounted on the drive’s control board and enables the user to 
employ precision isolated analog signals to interface three 
separate high resolution analog input signals, each of which may 
be either current or voltage (13-bit + sign). These signals are 
isolated from ground and the drive, but NOT from each other. 
These signals can act as a direct replacement for the three 
existing analog inputs available on the drive (3-channel individual 
mode), or the signals can be added together and used as a 
single frequency reference (3-channel addition mode). Gain and 
bias are adjustable for both modes using drive parameters. The 
polarity (sign) of the analog input can be used to control items 
such as motor direction and torque direction. 
 
Receiving: All equipment is tested against defect at the factory. 
Report any damages or shortages evident when the equipment is 
received to the commercial carrier who transported the 
equipment. 
 
Warning:  Hazardous voltage can cause severe injury or death. 
Lock all power sources feeding the drive in the “OFF” position. 
 
Caution: This option card uses CMOS IC chips. Use proper 
electrostatic discharge (ESD) protective procedures when 
handling the card to prevent I.C. damage or erratic drive operation. 
 
Important: 
1. If this option is being installed in a drive with an encoder (PG) feedback option card, that card will need to be temporarily 
removed to allow access to connector 2CN on the drive’s control board and TC1 – TC4 on the AI-040 option card.
2. Before installing this option, a technically qualified individual, who is familiar with this type of equipment and the hazards
involved, should read this entire installation guide.
Installation and Wiring:  
1. Disconnect all electrical power to the drive. 
2. Remove the drive’s front cover. 
3. Check that the “CHARGE” indicator lamp inside the 
drive is off.
4. Use a voltmeter to verify that the voltage at the
incoming power terminals (L1, L2, L3) has been 
disconnected. 
5. Option Card Installation: See Figure 1. Position the option card
above the control board’s 2CN connector and gently press the card 
into place. 
6. Wiring: Refer to Figure 3 and Tables 1 & 2. Make wire
connections between the AI-040 card and the drive as well as all 
peripheral devices. Observe the following: 
a) Determine whether a voltage or current signal will be used for 
each of the channels of the AI-040 card. Set selection jumpers 
accordingly. See Figure 2. 
b) Keep the AI-040 (i.e. control circuit) wiring separate from main
circuit input/output wiring. A separate metallic grounded 
conduit with only the option card’s wiring running through it is 
preferred. 
c) To prevent erroneous operation caused by noise interference,
use shielded cable for control signal wiring. Limit the distance to 
10m (33 feet) or less.
