PowerFlex 527 Drive Status Indicators
The fault status indicator is located between the LCD display and keypad. There
are also four status indicators located at the bottom right of the drive and can be
seen through the front cover of the control module.
NODE FLT 06 – LOST CTRL CONN Lost Controller Connection Fault Communication with the controller has been
lost. • Check Ethernet connection.
• Check controller and Ethernet switch
operation.
NODE FLT 07 – CLOCK SYNC Clock Sync Fault Drive's local clock has lost synchronization
with controller's clock and was not able to
resynchronize within allotted time. • Check Ethernet connection.
• Check controller and Ethernet switch
operation.
NODE FLT 09 – DUPLICATE IP ADDRESS Duplicate IP Address Fault Several consecutive updates from the
controller have been lost. Select an IP address not already in use on
the network.

NODE ALARM 01 – LATE CTRL UPDATE Control Connection Update Alarm Updates from the controller have been late. • Remove unnecessary network devices
from the motion network.
• Change network topology so that fewer
devices share common paths.
• Use high performance network
equipment.
• Use shielded cables.
• Separate signal wiring from power
wiring.
NODE ALARM 03 – CLOCK JITTER Clock Jitter Alarm The sync variance has exceeded the sync
threshold while the device is running in sync
mode. • Check the Ethernet connection.
• Check controller and Ethernet switch
operation.
NODE ALARM 04 – CLOCK SKEW ALARM Clock Skew Alarm The controller time and the drive's system
time are not the same. • Check the Ethernet connection.
• Check controller and Ethernet switch
operation.
NODE ALARM 05 – CLOCK SYNC ALARM Clock Sync Alarm Drive's local clock has lost synchronization
with controller's clock for a short time
during synchronous operation. • Check the Ethernet connection.
• Check controller and Ethernet switch
operation.
