8.2.3
Verify the power supply and motor connections:
• Verify that the power supply is connected to the board and is in working condition.
• Verify that the controller is in the correct socket; PIC18F on the “PIC” socket and
• Make sure the jumper settings are correct for the type of control selected.
• Verify that the motor connections on J9 are making proper contact.
• Check that the speed reference potentiometer (R14) has a sufficient level. Turn
• Check for overcurrent condition. If the motor has overloaded or the Fault detection

Try using a lower acceleration rate:
• If the motor still causes a Fault condition, check the motor power rating. It should
• Check the potentiometer R60 level. Set R60 for the correct current threshold level
• Check for correct socket selection and jumper selections for the type of control
• If using an alternative power supply for the motor, from the control power supply,

Check the motor power rating:
• The motor power rating should be within the board power rating specified.
• Check the potentiometer R60 level. Set R60 for the correct current threshold level
