Parameter; Simple Mode Parameters - Mitsubishi Electric FR-A800 Series Beginner's Manual

Parameter

6 Parameter
For optimum operation you need to configure your frequency inverter for the specific requirements
and specifications of the connected drive system and your application. All the necessary settings are
stored in numbered parameters in the inverter's memory – you only have to set them once because
this memory is not cleared when the power is switched off. All the parameters are preset to default val-
ues when the inverter leaves the factory so that the unit can be used at once.
There are two main classes of parameters, simple mode parameters and extended parameters. The
simple mode parameters should always be checked and configured before using the inverter but
many of the extended parameters are only needed for special or complex applications.
CAUTION:
E
Incorrect parameter settings can damage or (in extreme cases) even destroy the connected
motor. Take great care when you are setting the parameters and double-check the electrical
and mechanical specifications of the motor, your entire drive system and the connected ma-
chine before proceeding.
