CHAPTER 2: THEORY OF OPERATION Chapter Two: Theory of Operation 2.1 Introduction: This chapter contains the basic control theory of how brush-type and brushless servo motors and amplifiers operate. It also compares and contrasts the advantages and disadvantages of brushless and brush type motors and amplifiers to help you select which is best suited for your application.
SMA8115, SMA8215, and SMA8315 MANUAL 2.3 Servo Loops: A basic velocity-mode servo-loop for a brush-type motor is shown in figure 2.2a. An external controller commands a given velocity (RPM). The velocity-loop summing-amplifier compares this command with the actual motor velocity, supplied by a DC tachometer on the motor shaft, and produces an error voltage proportional to the difference between the actual and commanded velocity.
CHAPTER 2: THEORY OF OPERATION 2.4 Brushed Motors vs Brushless Motors: 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 figure 2.3, a brush-type motor has windings on the rotor (shaft) and magnets in the stator (frame).
SMA8115, SMA8215, and SMA8315 MANUAL Brushless Motors/Amplifiers Brushed Motors/Amplifiers Advantages Disadvantages No scheduled maintenance and no brush dust Motor brushes must be checked periodically for is generated. wear and excess brush dust. Higher RPM limits. Approximately 3000RPM maximum. Lower inertia/torque ratio. Higher inertia to torque ratio.
CHAPTER 2: THEORY OF OPERATION 2.6 The Advantages and Disadvantages of a Trapezoidal Amplifier System: A trapezoidal motor has three stator windings and together with the rotor magnets are designed so that the magnetic flux coupling between them produce a constant torque. The torque of the motor is proportional to the three stator phase currents which are 120 out-of-phase to the other two.

CHAPTER 5: CONFIGURATION 5.4.3 Encoder Output Resolution Configuration: Refer to Appendix B drawing 8000-1430 and 8000-1431. There are nineteen standard resolutions. Up to four resolutions are contained in a single PLD. To configure the pre-amp for a given resolution, ensure that you have the correct PLD (U13) and then configure the dip-switches S1-1, S1-2, S3-7 and S3-8 as shown below.
SMA8115, SMA8215, and SMA8315 MANUAL 5.4.4 Motor Pole Configuration: Dip-switch S3-1, S3-2, S3-3 and S3-4 configures the pre-amp for the number of poles in the motor. They are also used to set up certain calibration modes. Refer to the chart below and set the dip switches for the correct number of poles.
CHAPTER 6: START UP AND CALIBRATION Chapter Six: Start up and Calibration 6.1 Introduction: This chapter contains the procedure required for initial start up and amplifier calibration. Both trapezoidal and sine/resolver modes can be configured to run in velocity mode and current mode operations.
SMA8115, SMA8215, and SMA8315 MANUAL 6.3.1 Trapezoidal Mode Amplifier Calibration Procedure - Velocity Mode and Simulated Velocity Mode: The amplifier, in this configuration, receives an analog, bi-polar input command which is proportional to the required motor velocity. The amplifier receives velocity feedback from a tachometer which is usually mounted to the rear of the motor.
CHAPTER 6: START UP AND CALIBRATION 8. Adjust the Compensation pot CCW until the waveform is critically damped or one hook overshoot. Then proceed to step 10. 9. If the desired waveform cannot be obtained by adjusting the Compensation pot, back off(CCW) the Tach Gain pot a few turns and repeat step 8.
SMA8115, SMA8215, and SMA8315 MANUAL 6.4 Sine/Resolver Mode Amplifier Calibration: The following pots will be set during calibration: Note: RV1 and RV8 are single turn pots; RV2-RV7 and RV9-RV14 are 12-turn pots. Note: RV9-RV14 are factory set and should not be adjusted. Adjusting these pots voids warranty.
CHAPTER 6: START UP AND CALIBRATION The purpose of the following procedure is to set the system bandwidth to obtain a critically-damped response with the maximum possible tach gain. There are many possible settings of Tach Gain and Compensation which will yield a critically damped waveform.
SMA8115, SMA8215, and SMA8315 MANUAL 4. Connect the oscilloscope to ABS I (J1-7), and the battery box to the Signal 2 Signal- ended Input (J1-3 and J1-4). The voltage on J1-7 is a function of motor current: 1V=10A. While pulsing a step input voltage, adjust the Current Limit for the desired peak current. If the desired peak current cannot be achieved with the pot full CW, increase the input voltage or increase the Signal 2 Gain (RV3).
CHAPTER 6: START UP AND CALIBRATION 6.5.2 Three Phase Input Current Mode Amplifier Calibration Procedure: 1. Turn the Current Limit (RV4) to mid position, phase R (RV1) full CCW, phase S (RV2) full CCW and phase T (RV3) full CCW. 2.
SMA8115, SMA8215, and SMA8315 MANUAL 6.6 Calibration Setup Record: It is good practice to keep a record of all pot settings. Doing so will facilitate calibration on future units and repair on this unit. Although not a substitute for the calibration procedure, it will at least get you "in the ballpark."...
CHAPTER 6: START UP AND CALIBRATION 6.7 Resolver Alignment: Note: Glentek motors with built-in resolvers are factory aligned. Consult a Glentek applications engineer prior to attempting a resolver realignment. Failure to do so may void the warranty. Note:Consult a Glentek applications engineer before aligning a non-Glentek motor/resolver. Some motor/resolvers require procedures other than that described here.

CHAPTER 7: MAINTENANCE, REPAIR, and WARRANTY Chapter Seven: Maintenance, Repair, and Warranty 7.1 Maintenance: Glentek amplifiers do not require any scheduled maintenance, although it is a good idea to occasionally check for dust build-up or other contamination. 7.2 Amplifier Faults: If an amplifier should cease to operate and one or more of the fault LED's are lit, review the sections which follow on the fault in question for information and possible causes.
SMA8115, SMA8215, and SMA8315 MANUAL 7.2.2 Under Voltage Fault: When the +15VDC is below +12VDC, a level that would cause unreliable operation, the Run LED will turn off, a Fault Output is generated, and the amplifier is inhibited. This is not a latched condition: that is, if the problem is resolved the amplifier will resume operation.
CHAPTER 7: MAINTENANCE, REPAIR, and WARRANTY 7.2.6 Over Temp Fault: When the heatsink and or motor temperature has reached a level that, if exceeded, would damage the output transistors or the motor, the Run LED will turn off, the OVER TEMP LED is latched on, a Fault Output is generated, and the amplifier is inhibited.
SMA8115, SMA8215, and SMA8315 MANUAL 7.4 Factory Repair: Should it become necessary to return an amplifier to Glentek for repair, please follow the procedure described below: 1. Reassemble the unit, if necessary, making certain that all the hardware is in place. 2.
