5 System Parameters5.1 Introduction to MICROMASTER System Parameters
The parameters can only be changed by using the Operator Panel (OP) or the
Serial Interface.
Parameters can be changed and set using the OP to adjust the desired prop erties
of the inverter, such as ramp times, minimum and maximum frequencies etc. T he
parameter numbers selected and the setting of the parameter values are indicated
on the optional five-digit LCD display.
Ø rxxxx indicates a display parameter, Pxxxx a setting parameter.
Ø P0010 initiates “quick commissioning”.
Ø The inverter will not run unless P0010 is set to 0 after it has been ac cessed.
This function is automatically performed if P3900 > 0.
Ø P0004 acts as a filter, allowing access to parameters according to th eir
functionality.
Ø 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 cha nged
in quick commissioning, then will be displayed.
Ø Busy Message
In some cases - when changing parameter values - the display on the OP
shows for maximum of five seconds. This means the inverter is busy
with tasks of higher priority.
5.1.1 Access Levels
There are three access levels available to the user; Standard, Ex tended and
Expert. The level of access is set by parameter P0003. For most applic ations, the
Standard and Extended levels are sufficient.
The number of parameters that appear within each functional group (selected by
P0004) depends on the access level set in parameter P0003. For f urther details
regarding parameters, see the Parameter List.
