  • Page 5: Things To Know Before Using This Equipment

    THINGS TO KNOW BEFORE USING THIS EQUIPMENT • Only qualified personnel should install or perform servicing procedures on this equipment. • Before performing any work on the unit, allow at least five minutes for the capacitors to discharge fully. • Voltage is present on unprotected pins when the Drive/Oscillator is o p- erational.

  • Page 6: Product Features

    Appendix A provides procedures for troubleshooting electrical interference problems. 1.2 - PRODUCT FEATURES The SLO-SYN SS2000MD4M-O Drive/Oscillator combines a bipolar, two-phase PWM drive which uses hybrid power devices and a con- trol/oscillator in one compact package. Micro-stepping at 1/32 step resolu- tion (6400 pulses/revolution) is used to ensure smooth low speed opera- tion.

  • Page 7: Section 2: Express Start Up Procedure

    SECTION 2: EXPRESS START UP PROCEDURE The following instructions define the minimum steps necessary to make your Drive/Oscillator operational. CAUTION: Always disconnect the power to the MD4M-O before connecting or dis- connecting the motor leads. FAILURE TO DO THIS WILL RESULT IN A SHOCK HAZARD AND MAY DAMAGE THE DRIVE.

  • Page 8: Section 3: Installation Guidelines

    SECTION 3: INSTALLATION GUIDELINES 3.1 - MOUNTING The MD4M-O is mounted by fastening its mounting brackets to a flat surface. Dimensions are shown in Figure 3.1. If the Drive/Oscillator assembly is mounted against a bulkhead, be sure to apply a thin coating of thermal com- pound (such as Dow Corning type 340 Silicone Heatsink Compound) be- tween the Drive/Oscillator and the mounting surface before fastening the unit in place.

  • Page 10: Motor Connections

    Cabling from the Drive/Oscillator to the motor should be done with a shielded, twisted-pair cable. The wires for each motor phase should be twisted together about six times per foot (0.3 m). Superior Electric offers the following motor cable configurations. These ca- bles have unterminated leads on both ends. Length...

    3.2.2 - POWER INPUT CONNECTIONS The dc input power is connected to terminals 5 and 6 of the 6-pin terminal strip (J2). 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.

Use this current level to obtain the torque shown. Switches 1 through 5 are used to select the current level. Select the desired operating current by setting the appropriate switch to position 1 (ON).

    4.5.5 Potentiometers On board potentiometers are provided for setting the following motion p a- rameters: Accel, Decel, Low Speed, and Run Speed. Run Speed can also be set via: a) external potentiometer, see Section 4.5.3. b) external voltage input 0-5V or 0-10V, see Section 4.5.4. This product is implemented using digital techniques.
