2.8 Adjusting parameters
Some parameters have a profound effect on the operation of the Drive.
They must not be altered without careful consideration of the impact on
the controlled system. Measures must be taken to prevent unwanted
changes due to error or tampering.
2.9 Safety of personnel
The Stop and Start controls or electrical inputs of the Drive should not be
relied upon to ensure safety of personnel. If a safety hazard could exist
from unexpected starting of the Drive, an interlock that electrically isolates
the Drive from the AC supply should be installed to prevent the motor being
inadvertently started.
The DC bus will remain energized if a voltage is applied to the output
terminals of the Drive.
Under certain conditions, the Drive can suddenly discontinue control of the
motor. If the load on the motor could cause the motor speed to be
increased, a separate method of braking and stopping the motor should be
used (eg. a mechanical brake).
Before connecting the
AC supply to the Drive, it is important that you
understand the operating controls and their operation. If in doubt, do not
adjust the Drive. Damage may occur, or lives put at risk. Carefully follow
the instructions in this User Guide.
Before making adjustments to the Drive, ensure all personnel in the area are
warned. Make notes of all adjustments that are made.
Never work on a variable speed drive on your own: ensure that a suitably
qualified person is present to assist in an emergency.
