Chapter 5 Inverter Use
Description
5.1.3 Cautions for Operation
All the inverter functions are determined by set parameters. The
parameters of inverter ZVF200 series consist of the function codes
P00~P157, see the detail in Chapter 6 of this manual. The displayed
parameter value of each function code is the factory default value of the
inverter before EX factory, which can be modified by the user according
to his needs. It is noteworthy that a user shall change the relative function
parameters when he amends a parameter because some of the parameters
are inter-related . It is not recommended to modify the set parameter value
if there is no special requirement, for the factory default setting has been
done properly. Otherwise, this may cause damage to the inverter or
equipment due to error parameter.
In case there is an error alternation of the parameter, please initialize
the parameter with reference to the operation method in the clause 4.1.4
Parameter Initializing Restoring Factory Default Settings .
