Analog Input Option Card
AI-14B
Figure 2. Voltage/Current Selection Jumpers
Part Number: AI-14B.
Applicability: F7, G7, GPD515/G5, G5 HHP.
Note: If used in a GPD503/G3 or VCD703/VG3, refer to
Instruction Sheet 02Y00025-0296.
Introduction: The AI-14B analog input option board is
mounted on the drive’s control board and enables the user to
interface three separate high-resolution analog input signals,
each of which may be either voltage or current (13-bit + sign).
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-14B 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-14B 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-14B board. Set
selection jumpers accordingly. See Figure 2.
b) Keep the AI-14B (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 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.
7. 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.

Figure 4. AI-14B Block Diagram
Figure 4 shows two possible modes of operation for the AI-14B option card when installed in the drive. These modes are
selected by drive parameter F2-01 (AI-14B Input Selection). When F2-01 is set to “ 0 “, 3-channel individual mode is selected.
In this mode the AI-14B 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-14B option combines 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).

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

(4) 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.
