Safety Warnings
• The symbol shown at left indicates an important safety consideration. Please read
this manual carefully before performing any of the procedures contained herein.
Failure to follow these instructions may result in equipment damage, fire, severe
injury, or fatality.
• Have a qualified electrical maintenance technician install, adjust and service this
equipment. Follow the National Electrical Code and all other applicable electrical and
safety codes, including the provisions of the Occupational Safety and Health Act
(OSHA), when installing equipment.
• The symbol shown at left indicates additional information, shortcuts, or tips that do
not affect the safe operation of the drive.
• Reduce the chance of an electrical fire, shock, or explosion by proper grounding,
over-current protection, thermal protection, and enclosure. Follow sound maintenance
procedures.
• It is possible for a drive to run at full speed as a result of a component failure. Please
ensure that a master switch has been placed in the AC line to stop the drive in an
emergency.
WARNING!
Hazard of electrical shock! Circuit potentials are at 115 VAC or 230 VAC above earth
ground. Avoid direct contact with the printed circuit board or with circuit elements to
prevent the risk of serious injury or fatality. Disconnect incoming power and wait 60
seconds before servicing drive. Capacitors retain charge after power is removed.

General Information
The SimpleServo family of servo amplifiers is an economical solution to today's complex motion-
control needs. The SimpleServo combines a Digital Signal Processor (DSP), controller, heat sink and
power supply in one standalone, DIN-rail mountable or panel-mounted unit. The SimpleServo can be
operated as a stand-alone unit or as a digital amplifier.
The SimpleServo controls brushless motors with a high switching (carrier) frequency for virtually silent
operation. Most servomotors used today require high precision control and a smooth, sinusoidally
commutated signal. An on-board DSP provides commutation by generating the three-phase sine wave,
using feedback information from an optical encoder.
The servo will accept feedback from an encoder that includes Hall sensor feedback information. It
accepts commands from a variety of sources, including analog voltage, PWM and internal reference
signals. The control will operate in current mode (torque), velocity mode, or position mode (step and
direction). Upon initial start up, the motor is commutated using the hall sensors-for the first two or three
mechanical degrees of motor rotation-to map the encoder; the Hall-effect information is unnecessary
thereafter.
The SimpleServo's built-in RS-232 serial communications port and servo control program,
MotionView™, make programming extremely simple. In fact, you could be up and running in less
than thirty minutes! Each SimpleServo unit is an amplifier, power supply, controller and heat sink
integrated into a single standalone package. The SimpleServo will only accept an encoder with Hall or an
encoder with hall-commutation tracks encoded on the feedback device.

Installation
WARNING!
Hazard of electrical shock! Circuit potentials are at 115 VAC or 230 VAC above earth
ground. Avoid direct contact with the printed circuit board or with circuit elements to
prevent the risk of serious injury or fatality. Disconnect incoming power and wait 60
seconds before servicing drive. Capacitors retain charge after power is removed.
• The SimpleServo must be mounted vertically for safe operation at the maximum
current rating.
• Printed circuit board components are sensitive to electrostatic fields. Avoid contact
with the printed circuit board directly. Hold the SimpleServo by the case only.
• Protect the control from dirt, filings, airborne particles, moisture, and accidental
contact. Provide sufficient room for access to the terminal block.
• Mount the control away from other heat sources. Operate within the specified
ambient operating temperature range. Additional cooling with an external fan may be
recommended in certain applications.
• Avoid excessive vibration to prevent intermittent connections.
• DO NOT connect incoming power to the output motor terminals (U, V, W)! Severe
damage to the SimpleServo will result.
• Do not disconnect any of the motor leads from the SimpleServo unless power is
removed or the control is disabled. Opening any one motor lead may cause failure.
