Introduction to MICROMASTER system parameters

The parameters can only be changed by using the BOP, the Advance
Operator Panel (AOP) or the Serial Interface.
Parameters can be changed and set using the BOP to adjust the desired
properties of the inverter, such as ramp times, minimum and maximum frequencies
etc. The parameter numbers selected and the setting of the parameter values are
indicated on the optional five-digit LCD display.
rxxxx indicates a display parameter, Pxxxx a setting parameter.
P0010 initiates "quick commissioning".
The inverter will not run unless P0010 is set to 0 after it has been accessed.
This function is automatically perform if P3900 > 0.
P0004 acts as a filter, allowing access to parameters according to their
functionality.
If an attempt is made to change a parameter that cannot be changed in this
status, for example, cannot be changed whilst running or can only be changed
in quick commissioning, then
Busy Message
In some cases - when changing parameter values - the display on the BOP
shows
with tasks of higher priority.
5.1.1 Level
There are four levels of user access, Standard, Extended, Expert and Service
selectable by parameter P0003. For most applications, Standard (P0003 = 1) or
Extended parameters (P0003 = 2) are sufficient.
The number of parameters that appear within each functional group depends on
the access level set in parameter P0003. For further details regarding parameters,
see the Parameter List on the Documentation CD-ROM.
