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.
