Advanced Digital SimpleServo SS504 User Manual
                                  | |
4General InformationThe Advanced Digital SimpleServo family of servo amplifiers is an economical solution to today’scomplex 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 silentoperation. Most servomotors used today require high precision control and a smooth, sinusoidallycommutated signal. An on-board DSP provides commutation by generating the three-phase sinewave, using feedback information from an optical encoder.The servo will accept feedback from an encoder that includes Hall sensor feedback information. Itaccepts commands from a variety of sources, including analog voltage, PWM and internal referencesignals. The control will operate in current (torque) mode, velocity mode, or position (step anddirection) mode. Upon initial start up, the motor is commutated using the hall sensors—for the firsttwo or three mechanical degrees of motor rotation—to map the encoder; The hall-effect information isunnecessary 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 lessthan thirty minutes! Each SimpleServo unit is an amplifier, power supply, controller and heat sinkintegrated into a single standalone package. The SimpleServo will only accept an encoder with Hall oran encoder with hall-commutation tracks encoded on the feedback device. |
