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 op-
erational.
•Motors powered by the Drive/Oscillator may develop extremely high
torque. Be sure to disconnect power to the unit before doing any me-
chanical work.
CAUTION:
The SLO-SYN®SS2000MD4M-O is designed for 24 to 40 Vdc input only
(see Section 4.2, Electrical Specifications, Page 11).
WARRANTY INFORMATION
Reconfiguration of the circuit in any fashion not shown in this manual will
void the Warranty.
Failure to follow the installation guidelines as described in Section 3 will void
the Warranty.
SECTION 1: INTRODUCTION
1.1 - USING THIS MANUAL
It is important that you understand how the SLO-SYN®SS2000MD4M-O
Drive/Oscillator is installed and operated before you attempt to use it. We
strongly recommend that you read this manual completely before pro-
ceeding with the installation of this unit.

Page 4SS2000MD4M-O
This manual is an installation and operating guide to the SLO-SYN
SS2000MD4M-O Drive/Oscillator. Section 1 gives an overview of its fea-
tures. Section 2 describes the steps necessary to place the MD4M-O 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 easily referenced infor-
mation concerning electrical, mechanical and environmental specifications.
The procedure for setting the motor current level and connection of Oscillator
I/O are also covered in this section.
Torque versus speed characteristics with all appropriate SLO-SYN Stepper
Motors are given in Section 5. Section 6, Troubleshooting, gives procedures
to follow if the Drive/Oscillator fails to operate properly.
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. The maximum running speed is 3,000 rpm. Features include:
•Switch selectable motor current levels of 1.0 through 3.5 amperes
•Microprocessor-based Digital Oscillator for accurate speed control
•Built-in Potentiometers for Accel, Decel, Low Speed, and Run Speed
•Full short circuit protection (phase-to-phase and phase-to-ground)
•Undervoltage and transient overvoltage protection
•Efficient thermal design
•Windings Off capability
•User selectable Automatic Current Reduction at standstill
•Compact size
•Sturdy all-aluminum mounting base
•Run Speed Control from Built-in Potentiometer or External Voltage Input

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.
Always operate the Drive/Oscillator with the Motor and unit enclosure
GROUNDED. Be sure to twist together the wires for each motor phase
as well as those for the dc input. Six twists per foot (0.3 m) is a good
guideline.
1. Check to see that the motor used is compatible with the Drive/Oscillator.
Refer to Section 4.4 for a list of compatible motors.
2. Set the correct current level for the motor being used and set the switches
per the instructions in Section 4.5.1. Heat sinking may be required to
maintain case temperature below +70 C (+158 F).
3. Select the desired motor current at standstill (50% or 100%) and set
switch #6 as described in section 4.5.2.
4. Select the appropriate run speed source (on board trim pot or external
input) and set switch #7 as described in Section 4.5.3. If an external run
speed voltage source is to be used select the appropriate voltage range
(0-5V or 0-10V) and set switch #8 as described in Section 4.5.4.
5. Wire the motor per the "Motor Connections" description in Section 3.2.
6. 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.
7. Set the desired Accel rate, Decel rate, Low speed, and motor running
speed using the appropriate potentiometers as described in Section
4.5.5.
NOTES: If the motor operates erratically, refer to Section 5, "Torque Versus
Speed Characteristics".
Clockwise and counterclockwise directions are properly oriented when
viewing the motor from the end opposite the mounting flange.

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. Do not use too much thermal compound. It is better to use too little
than too much.
Figure 3.1, Mounting Diagram
NOTE: Case temperature must not exceed +70° C (+158° F).
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 MD4M-O away from obvious electrical noise
sources. If possible, locate the unit in its own metal enclosure to shield it and
its wiring from electrical noise sources. If this cannot be done, keep the unit
at least three feet (0.9 m) from any noise sources.

3.2.1 - MOTOR CONNECTIONS
All motor connections are made via the 6-pin terminal strip. Terminal as-
signments are given below. Motor connections are shown in Figure 3.3.
J2 Pin Assignment
1 M1 (Phase A+)
2 M3 (Phase A-)
3 M4 (Phase B+)
4 M5 (Phase B-)
NOTE: Motor phase A is M1 and M3 and motor phase B is M4 and M5.
The motor frame must be grounded.
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.
