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. Important Note: When the wiring
from the driver to the step motor extends beyond 25 feet, consult the factory.
Current Adjust Setting (CUR. ADJ.)
The potentiometer R7 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...

Low Voltage Adjust (VLV ADJ.)
The potentiometer R26 is used to set the motor low voltage (VLV) supply which furnishes the current
necessary for holding (standstill) torque and low-speed running torque. Higher values for the low voltage
will produce more holding and low-speed torque. A proper VLV will produce a standstill current that is 65
to 100% of the rated motor current (i.e. for a motor rated at 1 Amp, VLV should be set so that the standstill
current is 0.65 to 1 Amps.

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.

Fault Protection
There are 3 types of fault detection. When a fault is detected, the driver turns off the motor current and the
dual LED indicates which type of fault occured. The upper LED is green during normal operation.

Troubleshooting
If a fault occurs, reset the fault by applying a logic “0” to the reset input (TB1 pin 3) for at least 10 msec (or
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 lower LED red?
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”...
