Introduction

This manual describes how to use the SP200 demo unit.

For complete product information, refer to Installing and
Operating the SP200 AC Drive (D2-3408).

1.1 What Is a Variable-Speed Drive?

A variable-speed drive is an electronic device that controls
the speed, torque, horsepower, and direction of an AC or DC
motor.

Variable-speed drives offer:

• Improved process control by enabling you to control
virtually any process variable and to control your process
remotely with electrical interfaces.

• Reduced operating costs by enabling you to match the
motor speed to the load requirements.

• Reduced maintenance by providing a “soft-start” capability
that limits inrush current to reduce stress on mechanical
parts.

1.2 About the SP200 Drive

Typical applications for the SP200 AC drive include fans,
pumps, conveyors, and other small machines where inside
panel or inside machine mounting is available.

The SP200 drive is best suited for applications with these
requirements:

• A three-phase 1/2 to 2 HP AC induction motor is used.

• Single-phase input ratings (up to 1.5 HP) operate on 115
V or 230 V and produce 230 V, three-phase output in both
cases.

Introduction

1-1

• Three-phase ratings available in both 230 V and 460 V.

• Operator control options include local keypad or remote

keypad. A CopyCat keypad is available for applications
where quick editing and transfer of settings to multiple
drives is desired.

The SP200 drive comes in three different control models to
match specific needs:

• Model A: Single Channel Analog - for control from one
analog signal or a speed pot.

• Model B: Preset Speed - for up to eight specific speeds
controlled by three on/off digital inputs.

• Model C: Dual Channel Analog - for applications that can
take advantage of an operation between two analog
signals. Choose from PI, add, or multiply functions.

2.2 Connecting Power to the Demo Unit

The SP200 AC drive demo unit is powered by a grounded
115 VAC input. Follow these steps to connect the power cord
to the demo unit.

Step 1. Stand the demo unit on a flat surface with the

handle and cover latches facing you.

Step 2. Open both latches and lift the cover. Then slide the

cover to the right to remove.

Step 3. The power cord is stored in the cover of the demo

unit. Press down on the spring-loaded fasteners
inside the cover to access the power cord.

Step 4. Turn the demo unit around and stand it on its feet so

that it faces you.

Step 5. Plug the power cord into the receptacle on the left

side of the demo unit.

Step 6. Plug the power cord into a grounded 115 VAC

outlet.

Step 7. Use the on/off switch located next to the power cord

to apply power to the unit, if necessary.
