Troubleshooting

ATTENTION: This 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. Wait ten (10) minutes for capacitors to discharge to safe voltage levels. Failure to observe this precaution could result in severe bodily injury or loss of life.

ATTENTION: Only qualified electical 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.

The VS1MD 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

•Fault Codes displayed on seven segment display

•Drive monitor and status parameters

•Entries in the fault queue

9.1Verifying that DC Bus Capacitors are Discharged Before Servicing the Drive

ATTENTION: DC Bus capacitors retain hazardous voltages after input power has been disconnected. After disconnectiong input power, wait ten

!(10) minutes for the DC Bus capacitors to discharge and then check the voltage with a voltmeter to ensure the DC bus capacitors are discharged before touching any internal components. Failure to observe this precaution could result in severe bodily injury or loss of life.

The drive’s DC bus capacitors retain hazardous voltages after input power has been disconnected. Perform the following steps before touching any internal components:

Step 1. Turn off and lock out input power. Wait 10 minutes after drive’s 7-segment display goes blank.

Step 2. Open the drive’s cover.

Step 3. Verify that there is no voltage at the drive’s input power terminals.

Step 4. Once the drive has been serviced, reattach the drive’s cover.

Step 5. Reapply input power to the drive.
