Isolated Analog Input Option Card
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.

d) If any of the control signal input terminals (TC1-TC3) are NOT used, jumper them to 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) Connect the option card ground wire (G1) to the drive’s ground terminal TB3 (12 for G5).
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.
7. Adjustment. There are no adjustments to be made on the AI-040 option; however, the drive will have to be programmed
for the input requirement(s) of the remote 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.

Figure 4. AI-040 Block Diagram
Figure 4 shows two possible modes of operation for the AI-040 option board when installed in the drive. These modes are
selected by drive parameter F2-01 (Input Selection). When F2-01 is set to “ 0 “, 3-channel individual mode is selected. In this
mode, the AI-040 option replaces the analog inputs on the drive’s main control board. See Table 3.
When F2-01 is set to “ 1 “, 3-channel addition mode is selected. In this mode, the AI-040 option adds the three channels
together as shown above. This composite signal becomes the primary speed reference when the reference source parameter
is set to “Option PCB” (b1-01 = 3).

When using the 3-Channel Individual Mode,
Channel 1 (TC1) becomes the primary speed reference.
Channel 2 (TC2) can be configured using parameter H3-09.
Channel 3 (TC3) can be configured using parameter H3-05.

To use the 3-Channel Addition Mode, parameter b1-01 (Reference Source) must be set to “ 3 “ (Option PCB)
Frequency Reference = TC1 + TC2

Warning: If the application requires that reverse motor rotation be prohibited, Parameter b1-04 must be set to “1” so
the motor will stop whenever the polarity of the input signal becomes negative.
