ProblemSuggested Things to Test
Red Fault LED on at Power Up Verify if Motor Halls, Power, and GND are not either disconnected or miswired.
Verify if Motor Phases are not either disconnected or miswired.
Verify that the Hall Sensor Spacing switch (SW1 - POS. 5) is properly s\
et for the motor 
used.
If a heavy load is present at power up, verify current limit setting is set appropriately 
and current latch (SW2 - POS. 2) is not set to the ON position.
Verify the Motor Hall Power is not overloaded.  This occurs when other external 
circuitry other than the motor halls is using this voltage reference for\
 power, i.e. motor 
encoder.
Verify the Freewheel input is not sinking or sourcing any current through\
 the opto-
diode.
Motor does not run Check if Red Fault LED is on.
Verify if Motor Halls, Power, and GND are not either disconnected or miswired.
Verify if Motor Phases are not either disconnected or miswired.
Verify the Run/Stop input is sinking or sourcing current through the opto-diode.
Verify the on-board/external speed setting is correct on SW1, pin 1 is co\
rrect.
Verify on-board or external speed adjustment not at 0VDC or 0%
If a Closed-Loop operation is required, verify the Closed-Loop settings are correct for 
the motor used.
Motor runs erratic, at high tem-
perature (above 70°C), or incorrect 
speed Verify if Motor Halls, Power, and GND are not either disconnected or miswired.
Verify Motor Phases are not either disconnected or miswired.
Verify the on-board/external speed setting is correct on SW1, pin 1 is co\
rrect.
Verify the Freewheel input is not intermittently sinking or sourcing any \
current through 
the opto-diode.
Verify the Run/Stop input is not intermittently losing any current sinking or sourcing 
through the opto-diode.
Verify that nothing is connected to the Direction inputs when the Auto Direction mode is 
selected.
If a Closed-Loop operation is required, verify the Closed-Loop settings are correct for 
the motor used.
Verify there are no large variations in the motor bus voltage by monitori\
ng the voltage 
input when open-loop operation is used.
Verify the motor is not damaged by trying another motor with the driver.
