Addendum - Models Containing the BLD32
#L010148
Driver Pack models DPS32001, DPS32PG1 and DPS32PS1 containing the BLD32 style driver now contain a new printed
circuit board (AA3840B). This change has been made primarily to reduce manufacturing costs, so that we can continue to
pass on savings to our customers. An additional change has been implemented to improve the fault detection circuitry which
will affect the way the fault LED blinks. There is also the addition of a Fault Output (pin 10) on the terminal block (formally was
a no connect) and the ability to accept 24VDC inputs.
Open (Two Blinks)
This indicates that there is an “open” or intermittent connection in one of the motor wires. Check the motor and the wiring for
opens. Another condition that may cause this type of fault, is when a large motor is ramped down too quickly and it loses its
position (stalls).
Low Voltage Too Low (Four Blinks)
This indicates that there is an excess amount of current being pulled from the driver or the input voltage to the transformer is
too low to provide the amount of current needed by the low voltage winding. Check the input voltage of the transformer to see
if the voltage is within the specified range.
Over Temperature (Five Blinks)
This is caused by the heat sink reaching a temperature of 80ºC. Make sure proper ventilation or an additional heat sink is
provided so the temperature does not reach this level. High Voltage Too High (Three Blinks)
This indicates that the input voltage of the transformer is too high. Check the input voltage of the transformer to see if it is
within the specified range. If a fault occurs, reset the fault by applying a logic “0” to the Reset Fault Input (pin 4) for at least 100ms or by cycling power off
for at least 15 seconds. After resetting, try to run the motor again. If the driver continues to fault, check the conditions listed
below. New Fault Protection (The Section on Fault Protection Inside the User’s Guide is No Longer Valid)
There are now five new types of fault detection. When a fault is detected, the driver turns off the motor current, the red fault
LED indicates which type of fault occurred and the Fault Output pin goes low. This output is able to stand off 50V and sink
50mA. Refer to the table below for LED fault indications.

Short (One Blink)
This indicates that the driver or motor has a phase shorted or there is a “short” in the motor cable or wiring. Check the motor
and the physical wiring for shorts. If the driver continues to sense shorts after the motor and wiring are determined to be
accurate, then the output transistors should be checked using a multimeter as follows:
1. Set the multimeter to diode test.
2. Place the 
red lead on ground (pin 7).
3. Touch the 
black lead to each phase (pins 1, 2, 12, and 13).
4. This should give readings between 0.450V and 0.550V.
5. If any readings are significantly less than 0.450V, then the unit has been damaged.
