GENERAL DESCRIPTION
The ANAHEIM AUTOMATION TM3000
is a low cost, bilevel step motor driver to be
used with 4-phase step motors. The
TM3000 comes mounted on easy to use
snaptrack, available in lengths up to 6 feet.
BILEVEL DRIVE
The basic function of a step motor driver is
to control the motor winding currents.
Motor performance is determined by how
fast the driver can increase and decrease
the winding currents. A rapid rise in
winding current is achieved by applying a
high voltage directly to a motor winding.
This rapid rise of current is also referred to
as the "kick" or operating current. When a
desired current level is reached, the high
voltage is turned off and a low voltage is
applied to maintain a suitable holding
current level. When a motor winding is
turned off, a rapid decrease in winding
current is achieved by routing the energy
in the collapsing field back to the power
supply through a high voltage path. The
high voltage supply furnishes the energy
necessary to maintain motor output torque
at high step rates thus providing high
mechanical power output. The low voltage
supply provides much of the current
needed at low step rates and all of the
holding current.

Bilevel drivers do not use high frequency
switching techniques as chopper drivers
do. Consequently, they do not create the
EMI, RFI, and motor heating problems that
are associated with chopper drivers.
EXCITATION MODE SELECTION
Users have a choice of dual-phase, Fullstep operation or Half-step operation.
Dual-phase, Full-step operation occurs by
energizing two phases at a time, rotating a
typical motor 1.8 degrees per step. Halfstep operation occurs by alternately
energizing one, and then two, phases at a
time, rotating the motor 0.9 degrees per
step. Full-step operation is only for
applications that specifically require that
mode, such as when retrofitting existing
full-step systems.
MOTOR ON/OFF
The Motor On/Off feature allows deenergizing a motor without disturbing the
positioning logic. After re-energizing the
motor, a routine can continue. This
reduces motor heating and conserves

power, especially in applications where
motors are stopped for long periods.
CLOCK, CCW AND DIRECTION
Pulses applied to the CLOCK input cause
the motor to step in the clockwise direction
if the DIRECTION Control input is a logic
"1" (or No connection), and in the
counterclockwise
direction
if
the
DIRECTION Control input is a logic "0".
Pulses applied to the CCW input cause the
motor to step in the counterclockwise
direction. Positive or negative going
pulses may be used (see Table 2).
PHASE INPUTS
The TM3000 has the ability to accept
phase inputs to control each of the 4 motor
phases. For example, a microcontroller can
be used to control the motor phases.
Terminals 1,2, 3, and 4 of TB2 are used as
the inputs for Phase 1, Phase 2, Phase 3,
and Phase 4 respectively. Either Positive
True Phase Inputs or Negative True Phase
Inputs may be used (see Table 2 and
Figure 1).

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.
