General Precautions In addition to the precautions listed throughout this manual, the following

statements which are general to the controller must be read and understood.

ATTENTION: Only personnel familiar with the 1391B-ES

Servo Controller and associated machinery should plan or

implement the installation, start-up and subsequent maintenance

of the controller. Failure to comply may result in personal injury

and/or equipment damage.

ATTENTION: An incorrectly applied or installed controller

can result in component damage or a reduction in product life.

Wiring or application errors, such as, undersizing the motor,

incorrect or inadequate AC supply, or excessive ambient

temperatures may result in malfunction of the controller.

ATTENTION: This controller contains ESD (Electrostatic

Discharge) sensitive parts and assemblies. Static control

precautions are required when installing, testing, servicing or

repairing this assembly. Component damage may result if ESD

control procedures are not followed. If you are not familiar with

static control procedures, reference Allen-Bradley publication

8000-4.5.2, Guarding Against Electrostatic Damage or any

other applicable ESD Protection Handbook.

Important: In order to maintain UL listing on Allen-Bradley 1391B-ES

Servo Controllers, the user must

provide power from a 1391 Isolation

Transformer. Use of any other transformer voids the UL listing.

The user is responsible for providing motor overload protection in

accordance with the National Electrical Code (NEC), and any other local

codes that may apply.

Controller Description The 1391B-ES Pulse Width Modulated Servo Controller is a dedicated,

single axis, AC servo controller. It has been packaged to require a

minimum amount of panel space while containing, as standard, a number

of features required by the machine tool and automated equipment

industries.

The 1391B-ES allows the user to achieve higher operating speeds with

purchased motors or from motors already in use. Depending on the motor,

the 1391B-ES can produce up to 30% more speed without loss of torque.

This can help achieve greater precision, a finer finished product and

increased production from existing machinery.
