MOTOR CONNECTIONS

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 motor's

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.
