Parameters List
Explanations
Parameter Name and abbreviation
PNU The Parameter Number
Note: this is equivalent to the MODBus register number (modbus address + 1)
R/W R means read only. RW means it can be changed
Locked by
mainswitch
If the parameter is cong locked it means that the value can only be changed when the main switch is OFF
Default The default value of the parameter (factory setting)
Par min./Par max. Parameter minimum and Parameter maximum range.
Par. Scale This shows the scaling factor of the value
*1) means that there is no scaling
*10) means that the read value is 10 times larger than the actual value
Warning:
In modbus
Values are read / written as
16 bit integer values without
decimals. The values may need
to scale as shown on the table.
