THINGS TO KNOW BEFORE USING THIS
EQUIPMENT
•
Only qualified personnel should install or perform servicing procedures
on this equipment.
•
Before performing any wink on the unit, allow at least five minutes for
the capacitors to discharge fully.
•
Voltage is present on unprotected pbs when unit is operational.
•
Motors powered by this drive may develop (*Immo* high torque. Be
mire to disconnect power to this drive before doing any mechanical
wink.
CAUTION:
This unit Is designed for 24 to 40 Vdc input only bee Section 4.2,
Bectrical Specification& Pege 7).
WARRANTY INFORMATION
Reconfiguration of the circuit in any fashion not shown in this manual will
void the Warranty.
Failure b 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 SS2000MD4
Translator/Drive is installed and operated before you attempt to use it. We
strongly recommend that you read this manual *caplet* before pro-
eeedkle with the instelletion of this unit.
This manual is an installation and operating guide to the SLO-SYN
SSZ000MD4 Translator/Drive. Section 1 Om an overview of the Drive and
its features. Section 2 descrbes the steps necessary b 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, Med in Section 4, provide easily referenced infor-
mation concerning electrical, mechanical and environmental specification&
The procedure for seeing the motor current level is also covered in this
section.
• Toque versus speed characteristics with all appropriate SLO-SYN
Stepper Motors we given in Section 5. Section 6, Troubleshooting, gives
procedures to follow if the Transistor/Drive fails to operate woody.
Appendix A provides procedures br troubleshooting electrical interference
problems.
1.2 PRODUCT FEATURES
The SLO-SYN SS2000M04 Translator/Drive is a bipolar, adjustable speed,
two-phase PWAA drive which 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 capabilily
• Switch selectable lsep resolution
• Compact size
• Sturdy all-aluminum mounting bees

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 is a good
guideline.
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 switches as
described in Section 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.
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 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
NOTE: Case temperature must not exceed +70° C (+158° F).
When selecting a mounting location, it is important to leave at least two
inches (51 mm) 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.

NOTE: Motor phase A Is M1 and M3 and motor phase B Is M4 and
MS. The motor frame must be grounded.
Cabling from the drive 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.
Superior Electric offers the following motor cable configurations. These
cables have unterminated leads on both ends.
