Main Circuit Periodic Inspection
General
• Inspect equipment for discoloration
from overheating or deterioration.
• Inspect for damaged or deformed parts.
• Replace damaged components as
required.
• The drive has few serviceable parts
and may require complete drive
replacement.
• Inspect for dirt, foreign particles, or dust
collection on components.
• Inspect enclosure door seal if present.
Replace components if cleaning is not
possible.
•
Use dry air to clear away foreign
matter. Use a pressure of:
39.2 x 10
4
to 58.8 x 10
4
Pa (4 - 6 kg
•cm
2
).
Conductors and
Wiring
• Inspect wiring and connections for
discoloration, damage, or heat stress.
• Inspect wire insulation and shielding for
wear.
• Repair or replace damaged wiring.
Terminals
• Inspect terminals for stripped, damaged,
or loose connections.
• Tighten loose screws and replace
damaged screws or terminals.
Relays and
Contactors
• Inspect contactors and relays for
excessive noise during operation.
• Inspect coils for signs of overheating
such as melted or cracked insulation.
• Check coil voltage for over or under
voltage conditions.
• Replace damaged removable relays
contactors or circuit board.
Braking
Resistors
• Inspect for discoloration of heat stress on
or around resistors.
• Minor discoloration may be
acceptable.
• If discoloration exists check for loose
connections.
Electrolytic (bus)
Capacitors
• Inspect for leakage, discoloration, or
cracks.
• Inspect the relief valve for swelling,
rupture, or leakage.
• The drive has few serviceable parts
and may require complete drive
replacement.
Diodes and
IGBTs
• Inspect for accumulation of dust or other
foreign particles on components.
• Use dry air to clear away foreign
matter.
• Use a pressure of:
39.2 x 10
4
to 58.8 x 10

Control Circuit Periodic Inspection
General
• Inspect terminals for stripped, damaged
or loose connections.
•
Check for tightness.
• Tighten loose screws and replace
damaged screws or terminals.
•
If terminals are integral to a circuit
board then board or drive
replacement may be required.
Printed Circuit
Boards
• Inspect for unusual discoloration,
burning or strange odor, noticeable rust
or corrosion, proper seating of
connectors, dust, oil, or other
contamination.
• Re-seat loose connectors.
•
Replace PCBs if wiping or
vacuuming with anti-static vacuum
cannot clean the PCB.
•
Do not use solvents on PCBs.
•
Use dry air to clear away foreign
matter. Use a pressure of:
