SS2000MD4 6 400030-043 Rev G SECTION 1: INTRODUCTION 1.1 USING THIS MANUAL It is important that you understand how this SLO-SYN® 2000MD4 Translator/Drive is installed and operated before you attempt to use it. Read this manual completely before proceeding with the installation of this unit. This manual is an installation and operating guide to the SLO-SYN 2000MD4 Translator/Drive. Section 1 gives an overview of the Drive and its features. Section 2 describes the steps necessary to place the drive into operation. General wiring guidelines as well as the physical mounting of the unit and connections to the drive portion are covered in Section 3. Complete specifications, listed in Section 4, provide electrical, mechanical and performance specifications. The procedure for setting the motor current level is also covered in this section. Torque versus speed characteristics with all appropriate SLO-SYN Stepper Motors are given in Section 5. Section 6, System Checking, gives procedures to follow if the SLO- SYN 2000 drive fails to operate properly. Appendix A provides procedures for troubleshooting electrical interference problems. 1.2 PRODUCT FEATURES SLO-SYN 2000MD4 Translator/Drive is a bipolar, adjustable speed, two-phase PWM drive that uses hybrid power devices. It can be set to operate a step motor in full steps or half steps. The maximum running speed is 3,000 rpm. To reduce the chances of electrical noise problems, the control signals are optically isolated from the drive circuit. Features include: Switch selectable current levels of 0.5 through 3.5 amperes Full short circuit protection (phase-to-phase and phase-to-ground) Undervoltage and transient overvoltage protection Efficient thermal design Optically isolated inputs Windings Off capability Switch selectable step resolution Compact size Sturdy all-aluminum mounting base

SS2000MD4 7 400030-043 Rev G SECTION 2: EXPRESS START UP The following instructions define the minimum steps necessary to make your Drive operational. Always disconnect the AC power to the unit and be certain the "PWR ON" LED is OFF before connecting or disconnecting the motor leads. FAILURE TO DO THIS RESULTS IN A SHOCK HAZARD. Always operate the Motor and the Drive GROUNDED. Be sure to twist together the wires for each motor phase. Six twists per foot is a good guideline. 1. Check to see that the motor used is compatible with the drive. Refer to Section 4.4 for a list of compatible motors. 2. Set the correct current level for the motor being used per the instructions in Section 4.5. Heat sinking may be required to maintain case temperature below +70° C (+158° F). 3. Select the appropriate step resolution and set the front panel switches as described in Sec- tion 4.6. 4. Wire the motor per the "Motor Connections" description in Section 3.2. 5. Connect the power source to the DC input terminal strip. Be sure to follow the instructions for connecting the filter capacitor as described in Section 3.2, under Power Input. If the motor operates erratically, refer to Section 5, "Torque Versus Speed Characteristics". Clockwise and counter-clockwise directions are properly oriented when viewing the motor from the end opposite the mounting flange.

SS2000MD4 8 400030-043 Rev G Section 3: Installation Guidelines 3.1 MOUNTING The SLO-SYN Drive is mounted by fastening its mounting brackets to a flat surface as shown in Figure 3.1. If the drive assembly is mounted against a bulkhead, be sure to apply a thin coating of thermal compound between the drive and the mounting surface before fastening the unit in place. Do not use too much thermal compound. It is better to use too little than too much. Figure 3.1 Mounting Diagram Case temperature should not exceed +70° C (+158° F). Forced air cooling may be required to maintain temperature within the stated limits. When selecting a mounting location, it is important to leave at least two inches (51mm) of space around the top, bottom and sides of the unit to allow proper airflow for cooling. It is also important to keep the drive away from obvious noise sources. If possible, locate the drive in its own metal enclosure to shield it and its wiring from electrical noise sources. If this cannot be done, keep the drive at least three feet from any noise sources.

SS2000MD4 12 400030-043 Rev G 3.3.2 Power Input The DC input power is connected to terminals 5 and 6 of the terminal strip (J1). Terminal 5 [Vm(+)] is the power supply plus (+) connection and pin 6 [Vom(-)] is the power supply minus (-) connection. An unregulated supply similar to that shown in Figure 3.4 is preferable. If a regulated supply is used, it must be capable of operating with the added filter capacitor. A switching regulated supply may not be suitable for use with this drive. It is important that the capacitor (C1) be connected within three feet (0.9 meter) of the input terminals. The capacitor must be of the correct value and have the proper current and voltage parameters (see list of components). It is recommended that the power supply leads be twisted together (6 twists per foot). If the power supply is grounded, it must only be grounded on the negative side or the short circuit protection will not operate properly.

SS2000MD4 18 400030-043 Rev G SECTION 5: TORQUE VERSUS SPEED CHARACTERISTICS 5.1 MOTOR PERFORMANCE All stepper motors exhibit instability at their natural frequency and harmonics of that frequency. Typically, this instability occurs at speeds between 50 and 1000 full steps per second and, depending on the dynamic motor load parameters, cause excessive velocity modulation or improper positioning. This type of instability is represented by the open area at the low end of each Torque vs. Speed curve. There are also other instabilities that cause a loss of torque at stepping rates outside the range of natural resonance frequencies. One such instability is broadly defined as mid-range instability. Usually, the damping of the system and acceleration/deceleration through the resonance areas aid in reducing instability to a level that provides smooth shaft velocity and accurate positioning. If instability does cause unacceptable performance under actual operating conditions, use the following techniques to reduce velocity modulation. 1) Avoid constant speed operation at the motors unstable frequencies. Select a base speed above the motors resonant frequencies and adjust acceleration and deceleration to move the motor through unstable regions quickly. 2) The motor winding current can be reduced as discussed in Section 4.5. Lowering the current reduces torque proportionally. The reduced energy delivered to the motor can decrease velocity modulation. 3) Use the half-step mode of operation or use microstepping to provide smoother operation and reduce the effects of mid range instability. Microstepping reduces the shaft speed for a given pulse input rate.

SS2000MD4 35 400030-043 Rev G SECTION 6: SYSTEM CHECKING Motors connected to this drive can develop high torque and large amounts of mechanical energy. Keep clear of the motor shaft and all parts mechanically linked to the motor shaft. Turn off all power to the drive before performing work on parts mechanically coupled to the motor. If installation and operating instructions have been carefully followed, this unit should perform correctly. If the motor fails to step properly, the following checklist will be helpful in locating and correcting the problem. In General Check all installation wiring carefully for wiring errors or poor connections. Ensure that the proper voltage levels are being supplied to the unit. Be sure that the motor is a correct model for use with this unit. Specifically IF MOTOR DIRECTION (CW, CCW) IS REVERSED, Check For: Reversed connections to the Motor Connector. Reversing the phase A or the phase B connections reverses the direction of motor rotation. IF THE MOTOR MOTION IS ERRATIC, Check For: Supply voltage out of tolerance. Proper motion parameters (low speed, acceleration/deceleration, jog speed, home speed and feed rate). Set parameters on controller supplying pulse input to drive. Filter capacitor missing or too low in value. IF TORQUE IS LOW, Check For: All Windings Off active Correct current setting. Improper supply voltage. IF "FAULT" INDICATOR IS NOT LIT, Check For: Improper motor wiring. Grounded or shorted wiring to the motor or shorted motor. Improper motor type or incorrect Current Select switch setting If a malfunction occurs that cannot be corrected by making the preceding checks, contact Customer Support.

SS2000MD4 36 400030-043 Rev G APPENDIX A: TROUBLESHOOTING A.1 ELECTRICAL INTERFERENCE PROBLEMS Electrical interference problems are common with today’s computer-based controls. Such problems are often difficult to diagnose and cure. If such a problem occurs with your system, it is recommended that the following checks be made to locate the cause of the problem. 1. Check the quality of the AC line voltage using an oscilloscope and a line monitor. If line voltage problems exist, use appropriate line conditioning, such as line filters or isolation transformers. 2. Be certain all recommended wiring practices are followed for location, grounding, wiring and relay suppression (see Section 3.1). 3. Double-check the grounding connections to be sure they are good electrical connections and as short and direct as possible. 4. Try operating the drive with all suspected noise sources switched off. If the drive functions properly, switch the noise sources on again, one at a time, and try to isolate the one(s) causing the interference problems. When a noise source is located, try rerouting wiring, suppressing relays or other measures to eliminate the problem.
