Starting the drive system
ABB recommends you have the following
documents at hand when starting the drive system
for the first time after commissioning:
• Appendix E - Wiring diagrams, located on the CD,
to identify the circuit breakers to be switched on
• Chapter CDP control panel for information on
functions and features of the CDP control panel
• Chapter Power electronics and cabinet features,
section Doors and door locks, for information on
the door safety switch
Checks before starting the drive system
When the drive system is put into service after it
has been commissioned or after it has been taken
out of service for a longer period:
• Check that no tools or foreign objects are left
inside the cabinet
• Check that all auxiliary power supplies from
external sources are switched on
• Check that all internal circuit breakers of the drive
are closed
• Check that all covers are mounted and the doors
are closed and locked
DANGER: Hazardous voltage!
DANGER
All covers must be screwed in place to prevent
unintentional contact with energized components.
WARNING
Check that the grounding switch is in ungrounded
position

Starting the drive system from remote
When the drive system is operated from remote
through a higher-level control system or an
operator control desk, follow the instructions
in the appropriate manuals.
Starting the drive system locally
Note: The motor is controlled by the INU of
the drive. For this reason, the CDP control
panel must be connected to the INU to be
able to start the drive system locally. The
CDP control panel is only connected to the
AFE if it is required to view status and fault
messages of the AFE.
When the drive system is running, the CDP control
panel can be connected intermittently without
interrupting the operation of the drive.
However, to stop the drive system, the CDP control
panel must be connected to the INU. Switching the
CDP control panel from the INU to the AFE and back
is done with the drive selection mode.
See section Drive selection mode for further
information.
