Routine Maintenance of Electrical Drives
Major maintenance, troubleshooting and repair of drives should
be left to a qualified technician, following the drive manufacturer’s
recommendations. However, routine maintenance can help prevent
problems. Here are some tips:
• Periodically check the drive for loose connections or any other
unusual physical conditions such as corrosion.
• Vacuum or brush heatsink areas regularly.
• If the drive’s enclosure is NEMA 1, be sure vent slots are clear of
dust or debris.
• If the drive is mounted within a secondary enclosure, again be sure
vent openings area clear and that any ventilation fans are operating
properly.
• Unless it is otherwise necessary for major maintenance or repair, the
drive enclosure should not be opened.
