ATTENTION: Only qualified personnel familiar with the
construction and operation of this equipment and the
hazards involved should install, adjust, operate, and/or
service this equipment. Read and understand this
document in its entirety before proceeding. Failure to
observe this precaution could result in severe bodily
injury or loss of life.
ATTENTION: After disconnecting input power, wait two
minutes to insure that DC bus capacitors are
discharged. Failure to observe this precaution could
result in severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming
with all applicable local and national codes. Failure to

CHAPTER 1
Introduction
This manual describes how to use the SP120 demo unit.
For complete product information, refer to the SP120 AC
Drive Installation and Operation Manual (D2-3456).
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 SP120 Drive
The SP120 drive is best suited for applications with these
requirements:
• A three-phase 1/4 to 5 HP AC induction motor is used
• 115 V, 230 V, or 460 V input is available
• On-board operator controls are desired

1-2
Using the SP120 AC Drive Demo Unit
The SP120 drive comes standard with four control selections
to meet specific application requirements:
•Speed potentiometer
•Single-channel analog input
•Preset speeds (up to 15)
•PID

2.2 Connecting Power to the Demo Unit
The SP120 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.

CHAPTER 3
Programming Basics
To program the drive for a specific application, you display
the appropriate parameter and adjust it as required. The
parameters are used to define characteristics of the drive.
3.1 Parameter Menu Structure
Note that the dand Fgroup parameters are displayed in
sequence, but the A, b, and C parameters are grouped. You
must select the group before you can view the parameters
within that group.

3.2 Parameter Types
There are three types of parameters:
•Tunable parameters can be adjusted or changed while the
drive is running or stopped.
•Configurable parameters can be adjusted or changed
only while the drive is stopped.
•Read-only parameters cannot be adjusted.
3.3 How To Display and Adjust Parameter
Values Using the Keypad
The keypad is located on the front panel of the drive. You
must open the cover to access the programming keys.
