Servo Motor Description

Torque Plus motors feature a specially engineered housing that reduces motor length and increases continuous torque ratings. 

These high performance, three-phase, brushless, AC, synchronous servo motors are designed by Allen-Bradley to meet the stringent

requirements of high performance motion systems. This series of 460V, AC servo motors is intended to be used with the Allen-Bradley

1394 Motion Control System.

Connection Solutions

Several accessories are available with 460 volt 1326 cables. This

section highlights the most common application used with each

accessory, including:

• Right-angle connection.

• CE-compliant in-line connection.

• Remote in-line connection.

• Harsh environment connection.

• Double-ended bulkhead in-line connection.

Right-Angle Connection

This solution provides a low-profile right-angle connection at the motor

Linear-flex is defined as flex in one direction. The flex-rated cable is

not rated for twist-flex, which is flex in two directions. Power track

(linear-flex) cabling must not be used in twist applications.

Standard Allen-Bradley cables—1326-CCU-xxx for commutation and

1326-CPB1-xxx or 1326-CPC1-xxx for power—are tray-rated

(stationary) and should only be used for one-time flex applications.

• Power track cabling is required for applications where dynamic

linear flexing occurs. Use the following cables for these applications:

• 1326-CCUT-xxx (commutation for all motors)

• 1326-CPB1T-xxx (power for 1326AS-B3xxx and 1326AS-B4xxx motors)

• 1326-CPC1T-xxx (power for 1326AS-B6xxx and 1326AS-B8xxx motors)

Servomotor Cable

Series B Power cables (catalog number 1326-CPB1 and 1326-CPC1)

and commutation cables (catalog number 1326-CCU and 1326-

CECU) are available in lengths up to 90 m (295 ft) for standard, one

time flex applications. (PLTC 90° C 300V, AWM 90° C 300V for

1326-CCU and 1326-CECU, type TC 90° C 600V for 1326-CPB1

and 1326-CPC1.) Each cable features:

• UL Listed (file #E88699) cable assemblies.

• A braided cable shield for superior electromagnetic noise immunity.

• Molded push/pull connectors at the motor end for easy installation and maintenance.

Cable systems for 1394 Motion Control System:

• Standard single-connector cables.

• Right-angle connector cables.

• In-line system that uses bulkhead and double-ended cables.

• Harsh environment cables.

• High-resolution feedback cables.

Servomotor Options

Options available for the 1326AB include (option code designation or

catalog number in parenthesis):

• Integral spring-set holding brakes with 90V DC coils (-A4, -A5, -A7) or

24V DC coils (-K4, -K5, -K7).

• Brake Power Supply (1326-MOD-BPS) converts 115V AC to the

voltage needed for 90V DC brakes (-A4, -A5 and -A7).

• Shaft Oil Seal kits (1326AB-MOD-SSV-xx) for field installation of

Viton shaft seals. Motor disassembly is not required.

• NEMA Inch (-11) or IEC metric flange mount (-21) with metric shafts.

• Resolver Feedback Packages (1326AB-MOD-Vxxxx) provide 4.25”

(108 mm) transducers which offer absolute/vernier or single brushless

resolver feedback for use with Allen-Bradley 8600GP, IMC rack and S Class motion controllers.

• Junction Box Kit (1326AB-MOD-RJxx) available with axially mounted

connectors. Connector version allows the motor connectors to be

brought out axially to the motor (rather than radially) without further wiring.

• Secondary Feedback Mounting Kits (1326AB-MOD-Mx) for field

installation of an Allen-Bradley Encoder (845H) or resolver. Using a

1326AB motor with a 1391B-ES (or 1391-DES) with A Quad B

feedback (up to 2048 ppr) eliminates the need for encoder mounting.

• Blower Cooling Kit (1326AB-MOD-G3, G4) provides air over cooling

for up to 35% more torque output on most 1326AB “C” frame motors.

The kit can be field mounted on the rear of 1326AB-Cxx motors (in

cluding motors with brakes). For motors using secondary motor

mounted feedback (1326AB-MOD-M60), use option “G4.”

• Cables for power (1326-CPxx . .) and feedback (1326-CFx . . – com

mutation, 1326-CEx . . – encoders) are available in lengths up to 100 ft

.(30 m) for standard and high flex applications Power (1326ES-CPxx . .)

and commutation (1326ES-CFx . .) cables over 100 ft. (30 m), up to 300

ft. (90 m) are available when using 1391B-ES or 1391-DES drives only.

Basic Servomotor Description

The 1326AB Servomotors are a family of high performance, three-phase,

brushless AC synchronous motors designed by Allen-Bradley to meet the

stringent requirements of servo system applications. This series of standard

AC servomotors can be used with 1391 AC Servo Controllers. The perfor

mance parameters of these motors with selected amplifiers are listed on

page 8. The typical speed-torque curves (see page 9) depict the opera

tional envelope of these motor and controller combinations.

Each motor has the following standard features:

• Permanent magnet rotor for increased servo response.

• Three-phase sinusoidal wound stator field for direct transfer of heat to

ambient, and smooth operation at low speeds.

• Brushless resolver supplies position, commutation & velocity feedback

information. This also provides durability in harsh environments by not

having on-board electronics in the motor. 1391 A Quad B (optional)

encoder output (up to 2048 ppr) is generated via resolver feedback.

In thumbwheel test mode, the 56AMXN/B initially displays “Thumb Test Mode”

on the 4-character display, displays the switch settings for 5 seconds, then resumes

displaying “Thumb Test Mode”

For DCS slave operation, if the drop number and drop depth are individually valid

but the combination results in invalid drop numbers (for example, drop number 55,

drop depth 2), the module displays an error message on the 4-character display but

does not enter Thumbwheel test mode.

Prepare the Chassis for Module Installation

Before you install the 56AMXN/B module, you must install and connect a

ControlLogix chassis and power supply.

Determine Module Slot Location

The figure below shows chassis slot numbering in a 4-slot chassis. 

Slot 0 is the first slot and is always the leftmost slot in the rack (the first slot to the right of the power supply). 

You can use any size ControlLogix chassis and install the module in any slot.

You can also install multiple 56AMXN/B modules in the same chassis. 

You can install as many modules as your power supply can accommodate (i.e., number for which the power supply is rated).

Identify Module Features

Refer to the following figure to identify the hardware components of the 56AMXN/B module.

The module has:

• A label to indicate that it is a scanner for AutoMax

DCSNet and remote I/O

• A 4-character scrolling display (XXXX)

• 3 LEDs, labelled NET, CLX, and OK, to indicate the

status of the network, the connection to the ControlLogix processor, and its own internal state

• a 9-pin D-shell connector to connect to the DCS or remote I/O network

• switches at the top of the module to set the mode of operation and the drop number and drop depth

Set the Network Type and Node Address Switches

Before you install the module, you must set the network type, drop number and drop

depth using the switches at the top of the module.

The two switches at the left set the drop depth, the two at the right set the drop number.

The following table shows how to set the switches for each mode of operation.

For example, to configure the 56AMXN/B as a DCS slave with drop number 17,

drop depth 5, set the switches to 0, 5, 1, and 7 from left to right.

Any other settings are invalid and result in the module going into “Thumbwheel

test” mode. In thumbwheel test mode, the display shows the current switch settings.

It doesn’t go out of thumbwheel test mode until you cycle power.
