This section provides a description of suggested maintenance
activities and an in-depth troubleshooting chart.
Maintenance
The ULTRA 100 Series drive is designed to function with minimum
maintenance.
Periodic Maintenance
Normally the only maintenance required is removal of superficial dust
and dirt from the drive and a quick check of cabling insulation and
connections.
Cleaning
To clean the drive, use an OSHA approved nozzle that provides
compressed air under low pressure <20 kPa (30 psi) to blow the
exterior surface and the vents clean.
Cable Inspection
Inspect the cables, particularly the power connections, to verify the
connection.
●
All power connections should be torqued to 1.2 Nm (11 lb-in).
●
D-shell connectors can be inspected for proper seating and signal
continuity.
●
Visually inspect all cables for abrasion.
Data Transfer
After you have configured the drive and tuned the drive, the data
stored in the EEPROM personality module should be saved off-line.
Saving the parameters off line will allow you to clone several
machines with the same mechanics and provides an emergency
backup of the drive data.

Intro
ATTENTION: DC bus capacitors may retain hazardous
voltages after input power has been removed, but will nor-
mally discharge in several seconds. Before working on the
drive, measure the DC bus voltage to verify it has reached
a safe level or wait the full time interval listed on the warn-
ing on the front of the drive. Failure to observe this
precaution could result in severe bodily injury or loss of
life.
