General Description
The TM4500-80 driver is a unipolar step motor driver designed for 4 phase step motors. The TM4500-80 is
specifically designed to dynamically enhance driver performance while circumventing the effects of input
voltage variations. The TM4500-80 allows the option of using full-step or half-step operation, giving the user
the...

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...

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,...

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 R11 and JP4 setting will
produce a standstill current that is 70% of the rated current. Refer to the Anaheim Automation website or
catalog for motor current ratings. The charts below are a guide when selecting a motor and the jumper JP4
setting. (Refer to Jumper Functions for...

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...
