General Description
The TM4500 driver is a low cost, unipolar step motor driver designed for 4 phase step motors. The TM4500 
is a track mount driver, meaning that it can be quickly mounted on easy to use snaptrack (sold separatel\
y). 
The TM4500 allows the option of using full-step or half-step operation, giving the user the ability to step in 
either 1.8° or 0.9° increments. The driver can be powered by an AC or DC voltage. For AC operation, the 
driver may be purchased with a recommended step down transformer. A single transformer may be used 
to power up several drivers based on power consumption. A major advantage that  the TM4500 has over 
chopper drivers, is that the TM4500 is designed to use bilevel technology. This means that it has replaced 
the need for high frequency switching techniques, consequently it does not create the EMI, RFI, and motor 
heating problems that are associated with chopper drivers. This technique makes the TM4500 suitable for 
applications where low noise requirements are a must. It is especially useful for medical equipment, test 
instruments, positioning systems, and any other application where noise \
may be a problem.

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 neces-
sary 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 choppe\
r drivers do. Consequently, they 
do not create the EMI, RFI, and motor heating problems that are associat\
ed with chopper drivers.
Motor Connection
Refer to the hookup diagram for typical driver applications. Wiring connected to inputs must be separated 
from motor connections and all other possible sources of interference. 
Note: When connecting the driver to the step motor, consult the factory if more than 25 feet of cable will 
be used to extend between the motor and driver.
Phase Inputs
The TM4500 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.

Motor On/Off
The  motor  On/Off  feature  allows  the  de-energizing  of  a  motor  without  disturbing  the  positioning  logic. 
After reenergizing the motor, a routine can continue. This reduces motor heating and conserves power, 
especially in applications where motors are stopped for long periods.
Half Step/Full Step
The TM4500 has full-step or half-step operation. Full-step operation occurs by energizing two phases at 
a time, rotating a typical motor 1.8 degrees per step. Half-step 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.
Clock, CCW, and Direction
Pulses applied to the clock input cause the motor to move in the clockwise direction if the direction control 
input is a logic “1” (no connection), or in the counterclockwise direction if the direction control input is logic 
“0”. Pulses applied to the CCW input cause the motor to move in the counter clockwise direction. Either 
positive or negative going pulses may be used by setting jumpers in the appropriate position. To deter-
mine which setting to use, first consider the type of clock pulse output on the pulse generator or indexer 
(controller). If the clock output on the controller is open-collector type (sinking), then use the negative go-
ing jumper setting. If the clock output on the controller is a pnp or p-channel (sourcing) type, then use the 
positive going jumper setting. If the clock output on the controller is a TTL/CMOS type (totem pole), then 
either setting will work; but the jumper setting should be chosen based on the level of the clock output 
when the controller is not pulsing. If the clock is low when not pulsing, then use the positive going jumper 
setting. If the clock is high when not pulsing, then use the negative go\
ing jumper setting.

Power Requirements
The TM4500 can be powered by an AC or DC voltage (see specifications). For AC operation, the driver 
may be purchased with a recommended step down transformer. A single transformer may be used to 
power up several drivers based on power consumption.

Heating Considerations
The temperature of the heat sink should never be allowed to rise above 60 degrees Celsius. If necessary, 
air should be blown across the heat sink to maintain suitable temperatur\
es.
Low Voltage Adjust (VLV ADJ.)
The jumper JP4 is used to set the motor low voltage (VLV) supply which furnishes the current necessary 
for holding (standstill) torque and low speed running torque. The potentiometer R9 and JP4 setting will 
produce a standstill current that is 70% of the rated current. Refer to the Anaheim Automation website for 
motor current ratings. The charts below are a guide when selecting a motor and the jumper JP4 s\
etting.

Current Adjust Setting (CUR. ADJ.)
The potentiometer R9 is used to set the motor current. The pot should be set according to the motor’s rated 
current. This will produce a kick current of 1.4 times the rated motor current. (Refer to Wiring Diagram for 
location of current adjust potentiometer R9)
Fault Protection
There are 2 types of fault detection. When a fault is detected, the driv\
er turns off the motor current and 
the  LED indicates which type of fault has occurred. The LED is solid red during normal operation.
LED # of Blinks Description
1Open wire in the motor or cable.
2 Shorted wire in the motor or cable.
Note: If the driver goes into a fault condition, the fault may be reset by turning the power off for at least 
20 seconds. Refer to the Troubleshooting section for further details.

Troubleshooting
If a fault occurs, reset the fault by cycling power OFF for at least 20 seconds. After resetting, try to run the 
motor again. If the driver faults again then check the conditions listed\
 below.
Is the LED blinking twice?
This indicates that the motor has a phase shorted or there is a short in the motor cable or wiring. Check 
the motor and the wiring for shorts. If the driver continues to sense “shorts” after the motor and wiring \
are 
determined to be accurate, then the output transistor should be checked \
(see below).
Is the LED blinking once?
This indicates that there is an open or intermittent connection in one of the motor wires. Check the mo-
tor and the wiring for opens. Another condition that may cause this type of fault, is when a large motor is 
ramped down too quickly so that it loses it’s positioning.
Checking Output Transistors
 1. Set the multimeter to “diode test”.
  2. Place the red meter lead on ground (TB2 Pin 7).
  3. Touch the black meter lead to each phase (TB1, Pins 1,2,5 and 6).
  4. Readings should be between 0.450 VDC and 0.550 VDC.
  5. If any readings are significantly less than 0.450 VDC, then the unit has been damaged.
