Chapter 5 Preventative Maintenance and Component Replacement
Inspect the bus bars and cable connections. Check for any signs of overheating /
discoloration and tighten the bus connections to the required torque
specifications. Clean all cables and bus bars that exhibit dust build-up. Check for
corrosion, excessive temperature, or contamination.
Inspect Power Module Input and Output Power Connections
Verify that all Power Module input line cables and output bus connections are
properly torqued. Verify the output cables, VSB Cables and star connection
cables are properly torqued. Apply torque sealer if required. Check for corrosion,
excessive temperature, or contamination.
General Review Firmware and Hardware
Verify the firmware version on the HMI. Contact Rockwell Automation to
determine whether there are any enhancements or changes made to the Drive
Hardware and Control that would be valuable to the application.
Verify that the HMI is operational. Check the status indicators on the Control
Unit in the LV Control Cabinet register as normal.
Remove any dirt or foreign material. Wipe components with an anti-static cloth,
where applicable.
Inspect/Review Spare Parts
Check for signs of damage, dirt, or foreign material. See Spare Parts on page 127 .
ATTENTION: Ensure there is no power to the drive and wear an anti-static
wristband.
ATTENTION: Some circuit boards can be destroyed by static charges. Use of
damaged circuit boards may also damage related components. Use a grounding
wrist strap when handling sensitive circuit boards.
