Use the following flowchart to troubleshoot the unit.
!
ATTENTION: Only qualified personnel familiar with the construction and
operation of this equipment and the hazards involved should install,
adjust, operate, and/or service this equipment. Read and understand
this instruction manual in its entirety before proceeding. Failure to
observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: After disconnecting input power, wait five minutes and
check with a voltmeter to insure that DC bus capacitors are discharged.
The voltmeter should read zero volts. Failure to observe these
precautions could result in severe bodily injury or loss of life.
ATTENTION: If a megohmmeter (megger) is used, make certain that all
leads are disconnected between the motor and the drive. This will prevent
damage to electronic circuitry due to high voltage generated by the
megger. Use three wires to megger to ground. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
