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.

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.
