Troubleshooting the Drive
The MD65 constantly monitors its status and provides the following
ways to determine the status of the drive and to troubleshoot
problems that may occur:
•
LEDs on the drive (refer to figure 8.1 and table 8.1 for a
description of the LEDs)
•
Fault codes
10.1 Fault Codes
Faults codes indicate conditions within the drive that require
immediate attention. The drive responds to a fault by initiating a
coast-to-stop sequence and turning off output power to the motor.
The integral keypad provides visual notification of a fault condition
by displaying the following:
•
Flashing fault number (code) on the display. (See table 10.1 for
the fault code descriptions.)
•
Flashing FAULT LED
In addition, parameters d007-d009 act as a fault log. See the
parameter descriptions in chapter 9 for more information.

ATTENTION: The drive contains high voltage capacitors that
take time to discharge after removal of mains supply. Before
working on the drive, ensure isolation of mains supply from
line inputs [R, S, T (L1, L2, L3)]. Wait three (3) minutes for
capacitors to discharge to safe voltage levels. Darkened
display LEDs is not an indication that capacitors have
discharged to safe voltage levels. Failure to observe this
precaution could result in severe bodily injury or loss of life.
ATTENTION: Only qualified electrical personnel familiar with
the construction and operation of this equipment and the
hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other
applicable manuals in their entirety before proceeding. Failure
to observe this precaution could result in severe bodily injury
or loss of life.
