1.0. Introduction As the complexity and specification requirements of today's optical systems increase, so does the need for high performance, high accuracy, and compact mirror positioning systems. The MicroMax™ Series 670 system was designed for applications that require high performance specifications. The Series 670 Single axis Board-Level Mirror Positioning System consists of a single-channel servo amplifler on a 2.50" x 4.00" board and a high performance scanner.
2.0. Servo/Amplifier Specifications MicroMax 670XX Board Level Drive Electronics All angles are in mechanical degree. All specifications apply after a 1 minute warm up period. Analog Input Impedance: 200K + 1% ohms (Differential) lOOK + 1% ohms (Single Ended) Position Output Impedance: IK + 1 % ohms (For all observation outputs) Position Input Scale Factor: 0.
3.0. Description of Operation 3.1. Overview The 670 system's servo electronics are contained on a compact 2.5" x 4.0" multi-layer printed circuit board. Each servo board has been tuned to the customer's particular mirror inertia so that no adjustments are necessary unless the mirror inertia is changed. For those experienced in servo electronics, there is a tuning section included in section 6.0. Also included is a complete set of schematic and assembly drawings.
During system integration, ensure that there is sufficient clearance around and under the board to keep the circuits firom being shorted out, and that all of the connectors, adjustment potentiometers, and test points are accessible. 3.3. Input Power Refer to the 670 Schematic located in section 6.0. for details on this section. Input DC power is fed onto the board via the 4-pin male Molex connector, J3.
attained the proper level. Proper gauging of wire and power supply sizing should be considered during the design integration ofthe system. **Note: If the power supply cannot support the amount of current drawn by the servo board, the servo board will automatically shut down. This is part of the normal "turn-off' circuitry of the board. Do not use power supplies that "fold-back" in voltage when too much current is drawn.
be partially eliminated by the R77 trim on the 670 board. This trim is adjusted so that the AGC signal changes minimally through a full angular shaft rotation. This signal should not need adjusting during the normal lifetime ofthe scanner. This adjustment should only be made when retuning the original scanner or when matching a new scanner to the servo board. Refer to section 6.0 for details on this procedure. 3.6. Command Input 3.6.
3.6.4. Command Input Scale Factor Calculation The Command Input scale factor is defmed as the nimiber of volts required at the input of the servo board to cause the scanner's output shaft to rotate one mechanical degree. For some applications, fine control of this scale factor is critical. Also, since the input voltage is limited to +/-10V, this also sets the maximum contiollable angle or Input Range ofthe system. This Input Range is also referred to as the "fieldsize" ofthe system.
and the desired Command Input Scale Factor = 2:1 or 1.0V/° mechanical Thus, R30 = (Command Input Scale Factor * R29) / (Position Output Scale Factor x Slew Rate Limiter Voltage (jain x Command Input Scale Adjustment) or R30 = (l.OV/^ mechanical • lOKohm) / (0.5Vr mechanical x 1.074 x 0.9311) R30 = 20Kohm (Use a high quality metal film resistor, RN55C, for best thermal drift characteristics.
The command input offset adjustment potentiometer, Rl, confrols a DC input signal that is added to the normal input signal. RIO confrols the contribution of this input. The following equation can be used to determines the value of RIO for a desired Command Offset Range: RIO = (((+Vr) - (-Vr)) x R89 x (R29/R30)) / (Position Output Scale Factor x Command Offset Range) if Vr = 5V R89 = lOKohms R29 = lOKohms R30 = 20Kohms Position Output Scale Factor = 0.5V f mechanical Command Offset Range = 0.
exceed the capability of the power supply or the board's output amplifier, noise and even instability can result. By controlling the maximum slew rate of the input signal, the system's output amplifier can be kept from saturating. This is always advantageous for accurate positioning of the scanner. For some applications, fast large-angle positioning is not needed.
3.7.1. Class 1 Our class 1 servo consists of the following circuits: position differentiator, position amplifier, error integrator, current integrator, and summing amplifier. The ttansfer fimction can be characterized by the following differential equation: V(t) = Al • d rVpos(t)) + A2 • Vpos(t) + A3 • jError(t)dt + A4 • Jl(t)dt dt where: V(t) = output of summing amplifier Al - A4 = coefficients that are adjusted with the tuning pots R25, R28, R31, and R59 respectively.
The summing amplifier algebraically sums all four of these signals to obtain a composite signal that is sent to the output stage. During startup, a FET, Ql is tumed on slowly so that the servo has time to stabilize in a contiolled manner. Also, when an ertor condition is sensed, an analog switch, U15C, is shorted across this amplifier, thereby opening the loop and shorting the signal being sent to the output stage to ground.
used as another source of velocity information, hence damping. The advantage of this form of damping is its inherent low noise. Its bandwidth can be set high without degrading its signal to noise ratio. The overall bandwidth of the system can be extended much ftuther than with position differentiation alone. The current integrator is considered the high frequency damping source and is adjusted with R59.
3.8.2. Output Stage Disable The output amplifier is disabled during the power up sequence and recovery from a fault condition. See sections 3.11 and 3.13 for details. The output amp can also be manually disabled by grounding the TP4 "MUTE" test-point, or the Remote Shutdown input on J4.6. Grounding the Remote Shutdown input will disable the output amp by initiating a continuous fault recovery sequence, but grounding TP4 will not.

3.13. Protection Circuits The 670 board has various protection features, some of wiiich have been mentioned above. The primary purpose of this circuitry is to allow the servo to stabilize in a contiolled fashion during startup, and to shut down the scanner in a confrolled maimer should it detect any error conditions that could damage the scanner. The 670 system has two output signals that allow the user to monitor system status. One is the "FAULT OUT" signal available on the J4.
After 2 additional seconds (3 seconds from tum-on), the second stage of U8 resets and the following actions occur: 1. The error integrator is enabled via U15D. 2. The "position in" signal is enabled. 3. The scanner will begin to follow the input signal. 4. The "fault out" signal de-activates and the LED tums green. 3.13.2. Error Shutdown There are several error states that the protection circuitiy is designed to detect and guard against. They are: 1.
Do not operate the system under these condition or damage to the scanner may occur. See section 3.2. "Input Power" for a more detailed discussion on this. 3.12. Mirror Alignment Mode The mirror alignment mode shunt is W5. It allows the user to loosen the mirtor screws, align the mirrors, and retighten the mirror screws, without the system going unstable. It does this by lowering the loop gain of the system. When W5 is shorting pins 2 and 3, the system is in the normal operating mode.
4.0. Operating Instructions 4.1. Precautions and Warnings As a standard practice, keep the servo channel, scanner, and mirror together as a matched set. At Cambridge Technology, we have matched all three components and tested them as a system. Mixing and matching systems invalidates all of the calibrations that have been done. If mixing the systems is unavoidable, please follow the entire tuning procedure in section 6.0. to verify proper operation.
4.2. First Time Startup 1. Using the connector kit provided with your system, make the connectors for Jl and J3 as appropriate. Do not attach them to the 670 board at this time. After constracting the cables, double-check the wiring to ensure that everything is correct. Applying voltages to the wrong inputs would probably damage the scanner and the servo board which would void the warranty. Check the input power section, 3.3. 2.
11. For digital signals, input a 30 Hz square wave that spans about 5% ofthe field. For analog inputs, put in a square wave of about IV p-p at about 30Hz. For very large scanner/mirror systems, 30Hz may be too fast. For those systems, set thefrequencyto ~5Hz. 12. The scanner should immediately start moving in response to this input. Check the position out signal or look at the scanner itself and observe that it responds appropriately to the input signal. 13.
5.0. Limited Warranty CTI warrants that its products will be free of defects in material and workmanship for a period of one year from the date of shipment. CTI will repair or replace at its expense defective products retumed by the Customer under a Retum Authorization number issued by CTI. This warranty is void if the product is damaged by "misuse" or "mishandling" by any party not under the contiol of CTI. Misuse or mishandling will be determined by CTI.
6.0. Appendices 6.1. Tnne-up procedure 6.1.1. Precautions Read the following procedure completely before attempting to retune the system. Serious damage to the scanner could result if the servo were improperly adjusted! **Caution!! Shut the system down immediately if a resonance occurs. A resonating scanner will make a load noise that sounds like a buzzer or possibly like a highfrequencywhine. Do not confuse this with the normal sound the scanner makes while operating.
Once the scanner is tuned up, there is a procedure in section 6.1.9 that explains how to match the responses of two servo axis channels. For best X-Y scanner performance for most applications, the responses of both channels should be matched. 6.1.3. Required Tools and Materials 1. 2. 3. 4. 5. Dual tiace oscilloscope. Function generator - needs to have a sine and square wave output. Digital voltmeter Hand tools -jeweler's screwdriver flat-tip Clip lead with "micrograbber" ends. 6.1.4.
6.1.5. Adjusting the Position Output Scale Factor and the AGC Linearity The Position Output Scale Factor is precisely adjusted at Cambridge Technology and under normal circumstances never needs adjusting by the customer for the life of the servo board or scanner. If however the customer has changed the scanner originally sent with the servo board, (remember they are matched sets) use the following procedure to verify/adjust this signal.
2. Tum on the power. 3. The system should perform its normal tum-on process as described in section 4.2. above. 4. Adjust the Command Input Offset Adjustment trimpot, Rl to 0.000 volts as measured on R1.2 (wiper). Use TP2 or W7.2 as the ground reference. Center the scanner by inputting a signal into the Command Input so that Position Output voltage reads 0.000 volts as measured at TPl. 5. Reflect a laser beam onto the mirror of the scanner being adjusted.
13. Repeat steps 4. - 12. above until the desired Position Output Scale Factor and Linearity are obtained simultaneously. This is an iterative process and could take a few cycles through the procedure. 14. Again, it is recommended that the tuning procedure be followed to ensure the system's closed loop response it still properly adjusted. 6.1.5.2.
8. Measure the distancefromP2 to P3. Call this distance L2. 9. The Position Output Scale Factor, POSF, is obtained with the following formula: POSF = (VP2 - VPl) / ((arctangent(L2 / Ll / 2)) / 2) 10. Use R13 to set the POSF to 0.500 volts/° mechanical. Setting it to anything else can damage the scanner. 11. Ensure that the ACJC voltage on TP7 does not exceed +11V. If it does, the AGC amplifier may saturate as the scanner ages or temperatures change.
4. Apply a stable voltage into the Command Input. For digital input systems, send a 16384io output word to the digital input option, and set up W4 for DI non-inverting. For analog systems use the -VREF signal as a command input by connecting W7.3 as a single ended non-inverting input on W4. For both types, measure this voltage at W4 and record it. Call tiiis VINl. 5. Measure the voltage at Ul A. 1 or the input side of R30 and record it. Call it VIN2 6.
6.1.7. Closing the Servo Loop The following steps will close the servo loop and make all ofthe servo circuitry active. Again, it is stiessed that the following steps be read and understood thoroughly before proceeding! The purpose of this procedure is to adjust the servo loop trimpots so that the scanner/mirror system yields the fastest critically damped step response to a square wave input. Once this is obtained, the system will yield the best overall performance for any given input waveform.
5. Apply power to the system. The system should perform its normal tum-on sequence and both scanners should center themselves. Check the voltages at TPl to ensure that the scanners are somewhat near the center of the field. (Within ~1 voh.) If the scanners have not yet centered, tum R25 and R28 CW a little more while carefully watching the oscilloscope for any erratic behavior. Ensure that the servo loop is slightiy "stiff' by attempting to move the mirtor.

6.1.7.1.2. Fine Tuning The purpose of this section is to adjust more carefully the "shoulder" ofthe step response. 1. Setup the system by performing steps 1,4, and 6 from section 6.1.7.1.1. above. 2. Tum on the system power. 3. Adjust the input signal amplitude and offset so that the scanner now steps from -2.0° to 0.0° in a square wave fashion and at the same frequency as before. 4. Adjust the oscilloscope channel monitoring Vp to lOmV/div. The system should now look like Figure 8.
7. Tum R59 CW to eliminate the second overshoot. See Figure 11. This will make the first overshoot much larger. This will be corrected by R28 in the next step. : ['"• : . + T T r : Cn1=PosiDon Out ; CH2=Position In (;H2=Position In : [ 4- CHI- [ T i ^~-, T • : • / . 1 1• - Ol-ll mPnolinn rWrt: • j... p..l.;....i....i....^...:..., • CH1 : j • • • • ..:....: t • • • T • • • I . : . i . . . + ; fcH2 • ; ; .

6.1.7.1.3. Slew Rate Limiter Speed Adjustment Now that the small angle step response is set, the Slew Rate Limiter Speed Adjustment can be set to contiol the large angle response. The purpose of this adjustment is to keep the output stage ofthe servo from saturating for the largest and fastest possible move to be performed in the application. This is usually a full-field square wave. **Caution!! Ensure the scanner is properly heatsinked or damage to the scanner will result. 1.
6. As needed, adjust the Slew Rate Limiter Adjustment trimpot, R78, CW to slow the maximum slew rate of this large angle square wave as needed to keep the +Motor voltage from "squaring off' or saturating at the top of the first peak. Figure 16 shows this squaring off phenomenon. Slowing down the input signal will increase the large-angle step response time. However, the best setding performance will by achieved when the output amplifier is not allowed to saturate.
6.1.7.2 Class 0 The object of this procedure is to bring the servo gain up slowly while maintaining contiol ofthe scanners at alltimes.Move all the trimpots in small increments until experience with this system is obtained. If at any time during this procedure the scanners start to move erratically and make a loud buzzing noise, shut off the input power immediately and check the procedure to see if all steps were followed properly. 6.1.7.2.1. Coarse Tuning 1. Perform steps 1 - 7 in section 4.2. above. 2.
7. The scanner should now be responding to the input waveform, but should look very underdamped. Continue to turn R28 CW until the oscillations just die out before the next half cycle ofthe input signal. See figure 19. 8. Turn R25 CW to minimize the first overshoot and to minimize the oscillations. See figure 20. HfD 20omV % (inz 200mV ^M 5msfext/io/ 1.58V Figure 19.

6.1.8. Aligning the Mirror This procedure describes how to align the scanner mirror (load) while the servo is still active. Since the servo normally interprets someone holding or touching the mirror as a change in the inertia ofthe mirror, the system usually goes unstable. The Mirror Alignment Mode jumper, W5, when activated, lowers the loop gain, allowing the user to loosen the mirrors while the servo is still active, but without it going unstable.
Note: There may be a small offset in position from Mirror Alignment Mode to Normal Mode. This is due to any friction and/or spring in the scanner and because ofthe reduced loop gain. To account for this, offset the mirror the same amount but in the opposite direction of the original offset. This can be done because this offset is most often very repeatable.
6.1.9. Matching Two Servo (X and Y) Channels The purpose of this section is to match the dynamic performances of a dual axis X and Y system over all angles and frequencies. This system would consist of two 670 boards and two scanners. If the two channels are not closely matched, the system will not make sfraight lines when both channels are moved simultaneously. They also will not retrace a pattem when the beam is traveling in the opposite direction.

7. Input a full-field signal. See figure 34. While monitoring both channels, slow the faster channel's slew rate limiter trimpot, R78 to make the signals are equally fast. When done, the system should look like Figure and 35. 8. Repeat steps 6 and 7 until both conditions can be met and the outputs look like figures 32, 33, and 35.

6.2. 6740-XX Notch FUter Module 6.2.1 Background Theorv All mechanical systems are subject to vibrations via extemal excitation forces. The degrees of freedom of a vibrating mechanical system are defined by the number of independent coordinates required to identify its displacement during vibration. If we have a Cartesian coordinate system witii X, y, and z axis, then for a freely vibrating body, we can have six degrees offreedom.
6.2.2 Notch Filter Tuning Procedure The 6740-XX Notch Filter Module (NFM) is designed to be inserted into J5 of the 670 servo amp. The selection ofthe proper NFM is described below, along with tuning information.
e) Adjust the signal generator for about 200mV peak on current. This is a ballpark > figure. The main concern is that the current through the coil be large enough to view with good S/N ratio, but small enough to avoid excessive coil heating and mechanical vibration ofthe scanner while performing this test. Maintain the position signal near 0 volts by adjusting the DC offset control ofthe function generator accordingly. f) Slowly sweepfrequencyup while observing position and current on scope.
load combination,ringingmay still occur when tuning the scanner. This is especially true for high Q scanner torsional resonances. The viscous damping coefficient increases as the scanner RMS current (acceleration) increases, shifting the resonant frequency downward slightly with higher tuning speeds. This tends to de-stabilize the system when a fixed frequency, high Q notch filter is used. Lower Q notch filters can counteract this.
