Figure 2 is a hookup diagram for typical
driver applications.  Wiring connected to
inputs must be separated from motor
connections and all other possible sources
of interference.
IMPORTANT NOTE:  When the wiring
from the driver to the step motor extends
beyond 25 feet, consult the factory.
CURRENT SETTING
The potentiometer on the driver is used to
set the motor current.  See Table 3.  The
pot should be set according to the motors
rated current.  This will produce a standstill
current of 70% of the rated current and a
kick current of 1.4x the rated motor current.
Example:  For a motor rated at 2.0 amps per
phase, the POT should be set between 50
and 60.
POWER REQUIREMENTS
The TM3000 can be powered up by an AC
or DC voltage (see specifications).  For AC
operation, the driver may be purchased
with  a transformer (see Table 1).  A single
transformer may be used to power up
several drivers.
HEATING CONSIDERATIONS
The temperature of the heatsink should
never be allowed to rise above 60 degrees
Celsius.  If necessary, air should be blown
across the heatsink to maintain suitable
temperatures.
TM3000-1
The TM3000 is available with a mounting
plate for those who do not use track
systems.  The model number for this driver
with the mounting plate is the TM3000-1.
Dimensions are shown in figure 3.
