2 Product Overview
2 Product Overview
◆About This Product
Installation of the Analog Input Option AI-A3 allows the user to input a high precision, high
resolution analog signal reference to the drive. The option terminals can be set either as
separate functions for each terminal to use the multi-function analog input terminals on the
option for a higher resolution signal, or as a combined input where the drive adds the input
of all signals to the option to build the frequency reference.
The option has an input signal of -10 to 10 Vdc (20 kΩ) or 4 to 20 mA (250 Ω) with three
input channels, DIP switches to select voltage/current input, 13-bit signed (1/8192) input
voltage resolution, and 1/4096 current input resolution.
◆Applicable Models
The option can be used with the drive models in Table 1.

◆Installing the Option
Refer to the instructions below to install the option.
1. Shut off power to the drive, wait the appropriate amount of time for voltage to
dissipate, then remove the digital operator (D), front cover (C), and terminal cover
(E). Cover removal varies depending on drive size. Refer to the Quick Start Guide
packaged with the drive for directions on removing the covers.
DANGER! Electrical Shock Hazard. Disconnect all power to the drive and wait at least the amount of time
specified on the drive front cover safety label. After all indicators are off, measure the DC bus voltage to
confirm safe level, and check for unsafe voltages before servicing to prevent electric shock. The internal
capacitor remains charged even after the power supply is turned off.
NOTICE: Damage to Equipment. Observe proper electrostatic discharge procedures (ESD) when handling
the option, drive, and circuit boards. Failure to comply may result in ESD damage to circuitry.

remaining ground terminal and installation hole on the option (B) using the last
remaining provided screw (G).
Figure 5
Figure 5 Connect the Ground Wire
Note: 1. The option package includes three ground wires. Use the longest wire when plugging the option into
connector CN5-C on the drive side. Use the next longest wire when plugging the option into connector
CN5-B. Use the shortest wire when plugging the option into connector CN5-A. Refer to Option
Package Contents on page 8 for more information.
2. There are two screw holes on the drive for use as ground terminals (J). When connecting three options,
two ground wires will need to share the same drive ground terminal.
4. Set DIP switches S1, S2, and S3 on the option for current or voltage input on
terminals V1, V2, and V3. The default configuration is set to voltage input for all
terminals.

5. Prepare and connect the wire ends as shown in Figure 7 and Figure 8. Refer to
Wire Gauges and Tightening Torques on page 20 to confirm that the proper
tightening torque is applied to each terminal. Take particular precaution to ensure
that each wire is properly connected and wire insulation is not accidentally pinched
into electrical terminals.
WARNING! Fire Hazard. Tighten all terminal screws according to the specified tightening torque. Loose
electrical connections could result in death or serious injury by fire due to overheating electrical connections.
Tightening screws beyond the specified tightening torque may cause erroneous operation, damage the
terminal block, or cause a fire.
NOTICE: Heat shrink tubing or electrical tape may be required to ensure that cable shielding does not
contact other wiring. Insufficient insulation may cause a short circuit and damage the option or drive.

7. Route the option wiring.
Depending on the drive model, some drives may require routing the wiring through
the side of the front cover to the outside. In these cases, cut out the perforated
openings on the left side of the drive front cover as shown in Figure 10-A and leave
no sharp edges to damage wiring.
Route the wiring inside the enclosure as shown in Figure 10-B for drives that do not
require routing through the front cover.
Refer to the Peripheral Devices & Options section of the drive Technical Manual for
more information.
