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 unit is operational.
Motors powered by this drive may develop extremely high torque. Be sure to disconnect power to this
drive before doing any mechanical work.
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 this SLO-SYN SS2000-DP4 Translator/Drive is installed and
operated before you attempt to use it. We strongly recommend that you read this manual completely
before proceeding with the installation of this unit.
This manual is an installation and operating guide to the SLO-SYN SS2000-DP4 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 easily referenced information concerning electrical,
mechanical and environmental 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, Troubleshooting, gives procedures to follow if the Translator/Drive fails to operate properly.
Appendix A provides procedures for troubleshooting electrical interference problems.
1.2 PRODUCT FEATURES
The SLO-SYN SS2000-DP4 Dual Packaged drive system includes two independent stepper motor drives
and their motor power supply in a single packaged unit. Each drive is a bipolar, adjustable speed,
two-phase PWM circuit which uses hybrid power devices. It can be set to operate a step motor in
microstep mode at up to 20,000 microsteps per revolution. 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
•Choice of either Pulse/Direction or CW / CCW input capability
•Full short circuit protection (phase-to-phase and phase-to-ground)
•Undervoltage and transient overvoltage protection
•Overtemperature Protection
•Efficient thermal design
•Optically isolated inputs
•Windings Off capability
•Automatic Current Reduction (In –MM models)
•Switch selectable step resolution
•Compact size
•Sturdy cabinet with integral mounting flanges

SECTION 2: EXPRESS START UP PROCEDURE
The following instructions define the minimum steps necessary to make your Drive operational.
CAUTION:
Always disconnect the power to the unit before connecting or disconnecting the
motor leads. FAILURE TO DO THIS WILL RESULT IN A SHOCK HAZARD AND MAY
DAMAGE THE DRIVE.
Always operate the unit with the Motor and the Drive 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. 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.
3. Select the appropriate step resolution and set the switches as described in Section 4.7.
4. Wire the motor and I/O per the "Motor Connections" description in Section 3.3.
Connect the power source to the AC input terminal strip. Be sure to follow the instructions for connecting
the jumpers for 115 VAC or 230 VAC as described in Section 3.3, under Power Input.
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 GENERAL WIRING GUIDELINES
SLO-SYN 2000 drives use modern solid-state electronics to provide the features needed for advanced
motion control applications. In some cases, these applications produce electromagnetic interference
(EMI, or electrical "noise") that may cause inappropriate operation of the digital logic used in the drive, or
in any other computer-type equipment in the user's system.
In general, any equipment that causes arcs or sparks or that switches voltage or current at high
frequencies can cause interference. In addition, ac utility lines are often "polluted" with electrical noise
from sources outside a user's control (such as equipment in the factory next door). Some of the more
common causes of electrical interference are:
•power from the utility ac line
•relays, contactors and solenoids
•light dimmers
•arc welders
•motors and motor starters
•induction heaters
•radio controls or transmitters
•switch-mode power supplies
•computer-based equipment
•high frequency lighting equipment
•dc servo and stepper motors and drives
The following wiring practices should be used to reduce noise interference.
Solid grounding of the system is essential. Be sure that there is a solid connection to the ac system
earth ground. Bond the drive case to the system enclosure. Use a single-point grounding system for all
related components of a system (a "hub and spokes" arrangement). Keep the ground connection short
and direct.
Keep signal and power wiring well separated. If possible, use separate conduit or ducts for each. If
the wires must cross, they should do so at right angles to minimize coupling.
Note: Power wiring includes ac wiring, motor wiring, etc. and signal wiring includes inputs and outputs
(I/O), serial communications (RS232 lines), etc.
Use shielded, twisted-pair cables for Indexer I/O lines. BE SURE TO GROUND SHIELDS ONLY AT
ONE END, THE INDEXER/DRIVE END FOR OUTPUTS AND THE SWITCH OR SENSOR END FOR
INPUTS.
Suppress all relays to prevent noise generation. Typical suppressors are capacitors or MOV’s. (See
manufacturer’s literature for complete information). Whenever possible, use solid-state relays instead of
mechanical contact types to minimize noise generation.
If you are experiencing problems with drive operation which might be related to EMI, refer to Section 6.0
for Troubleshooting pointers.

3.2 MOUNTING
The SLO-SYN Drive is mounted by fastening its mounting brackets to a flat surface as shown in Figure
3.1.
Figure 3.1, Mounting Diagram
NOTE: The unit should be mounted upright so that air flow will not be obstructed. 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 electrical noise sources. If possible, locate the
drive unit in a 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.

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 to the motor should be done with a shielded, twisted pair cable. As a guideline, the
wires for each motor phase should be twisted about six times per foot. Terminate the cable shield to the
"MOTOR SHIELD" terminal on the DP4 unit case. The recommended maximum cable length is 75 feet.
Superior Electric offers the following motor cable configurations. These cables have unterminated leads
on both ends.
