6 Maintenance, Diagnostics, and Troubleshooting

6.1 Maintenance and Service

Under normal operating conditions and load profiles, the
drive system is maintenance-free throughout its designed
lifetime. To prevent breakdown, danger, and damage,
examine the drive system at regular intervals depending
on the operating conditions. Replace worn or damaged
parts with original spare parts or standard parts. For
service and support, refer to vlt-drives.danfoss.com/support/
service/.
Inspect the following items if the drive system is installed
in an aggressive environment.
•
Built-in filter mats, cooling fans, and the heat sink
require periodic cleaning. Determine the
frequency of service based on the system's
exposure to dust and contaminants.

6.2 Periodic Maintenance

Dust
When dust accumulates on electronic components, it acts
as a layer of insulation. This layer reduces the cooling
capacity of the components, and the components become
warmer. The resulting hotter environment decreases the
life of the electronic components. Keep the heat sink and
fans in the drive modules free from dust build-up.

6.3 Status Messages

When the drive system is in status mode, status messages
are generated automatically and appear in the bottom line
of the LCP display (see Illustration 6.1.) Status messages are
defined in Table 6.1 to Table 6.3.

The drive system does not react to any control
signal until [Auto On] or [Hand On] is pressed.
The start/stop commands are sent via the
control terminals and/or the serial communi-
cation.
The navigation keys on the LCP can be used
to control the drive system. Stop commands,
reset, reversing, DC brake, and other signals
applied to the control terminals can override
