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...

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...

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 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...

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...
