Page 4: Overview
Application Guide This guide is designed to assist the customer with the integration of Glentek’s Amplifiers and Motors to their systems, utilizing high response micro stepping servos instead of low resolu- tion stepper motors. The difference between stepper motors and servo motors with high resolution encoders will be pointed out and examples will be given. -
Page 5: Servo Motor Versus Stepper Motor
Servo Motor Versus Stepper Motor Stepper motor versus servo motor is a question that has been asked by many people with projects where they could incorporate either motor. There are many benefits that the servo system has over the stepper system. Servo motors and servo amplifiers are designed to maximize efficiency between the motor and amplifier. - Page 6 Application Guide The Glentek Nema 34 and Nema 42 servo motors are supplied with 5000 line encoders. This high resolution (20,0000 counts per revolution) provides a smoother higher bandwidth velocity loop for fine machining finishes. To take full advantage of this high step resolution capability, the pulse data required from the Artsoft software would have to be as shown in the following example: A milling machine with a 5 pitch ball screw traveling at 400 inches per minute would require the follow- ing calculated data rate:...

Page 7: Selecting A Glentek Servo Motor To Replace A Stepper Motor
Selecting a Glentek Servo Motor to Replace a Stepper Motor This section provides the specifications of various stepper motors so they can be compared to equivalent servo motors. This should help in clearing up some of the confusion involved in choosing a servo motor to replace a stepper. -
Page 8: How To Choose The Correct Amplifier
Application Guide How to Choose the Correct Amplifier Glentek produces a wide range of amplifiers. Some amplifiers have built in DC power supplies, referred to as “Stand Alone”, while others are referred to as a module that requires customers to furnish DC power supply. -
Page 9: Sound Logic Breakout Board
Sound Logic Breakout Board The Sound Logic breakout board can be used with a Glentek motor and drive combination. The Sound Logic board enables a customer to use their computer to send pulses to this board. This board then sends these pulse and direction signals to the amplifier. The board connects directly to the parallel printer port on a standard computer. -
Page 10: Artsoft Controls Software
Application Guide Artsoft Controls software enables a computer to turn a manual milling machine into a computer con- trolled machine. This software was used in conjunction with the Sound Logic breakout board to effec- tively evaluate the needs of the CNC community. This software is complex for the novice user. How- ever, Artsoft has many forums where help can be found and Artsoft also offers phone technical service. -
Page 11: Advantages Of Using Glentek Microstepping Servo Amplifiers
Advantages of using Glentek Microstepping Servo Amplifiers Glentek Omega series digital PWM servo amplifiers offer the latest in high performance DSP control of both brushless and brush type motors. With extensive utilization of surface mount technology and spe- cial heat transfer techniques, the Omega series offers one of the world’s most powerful products for a given form factor. -
Page 12: Brushless Versus Brush-Type Comparison
Application Guide Brushless versus Brush-type Comparison There are two basic types of motor design that are used for high-performance motion control systems: Brush-Type PM (permanent magnet), and Brushless-Type PM. As you can see in the figure, a brush- type motor has windings on the rotor (shaft) and magnets in the stator (frame). In a brushless-type mo- tor, the magnets are on the rotor and the windings are in the stator. - Page 13 Glentek Inc. 208 Standard Street, El Segundo, California 90245, U.S.A. (310) 322-3026...
