Troubleshooting the Drive
The SP600 drive provides the following ways to determine the
status of the drive and to troubleshoot problems that may occur:
• Ready LED on the drive cover
• User-configurable and non-configurable alarms
• User-configurable and non-configurable faults
• Entries in the fault queue
• Drive status parameters
12.1 Verifying that DC Bus Capacitors are
Discharged Before Servicing the Drive
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 5 minutes.
Step 2. Open the drive’s cover.
Step 3. Verify that there is no voltage at the drive’s input power
terminals.
Step 4. Measure the DC bus potential with a voltmeter while
standing on a non-conductive surface and wearing
insulated gloves. Refer to figure 12.1.

!
ATTENTION: DC bus capacitors retain hazardous voltages
after input power has been disconnected. After disconnecting
input power, wait five (5) 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.
