3. PARAMETERS AND SETTINGS
3.1 Parameter Lock (Loc) and Field Parameters
In order to protect important parameters from being modified by mistake, but also offer enough flexibility for field
control, parameter lock (Loc) and field parameters are introduced.
The parameters need to be displayed and modified in the work field are called Field Parameters. The set of field
parameters is a subset of the entire parameter set, and can be freely chosen by the user.
Loc can authorize different security right as below:
Loc=0, allowed to modify field parameters and setpoint, and execute auto tuning;
Loc=1, allowed to modify field parameters and setpoint, but can’t execute auto tuning;
Loc=2, allowed to modify field parameters, but can’t modify setpoint or execute auto tuning.
Loc=3

255: can only modify “Loc”
Setting Loc=PASd (Password, a number between 256 and 9999. The initial value is 808) and then pressing
to
confirm, can enter the whole parameter table and modify all parameters.
1 to 8 field parameters can be defined by parameters EP1to EP8. If the number of the field parameters is less than 8,
the first idle EP parameter should be set to “nonE”. The initial values of EPs and Loc are EP1=HIAL, EP2=LoAL,
EP3=HdAL, EP4=LdAL, EP5=nonE, EP6=nonE, EP7=nonE, EP8=nonE and Loc=0.
You can redefine field parameters and Loc to change operation style. For example, you can execute auto tuning
from field parameter instead of by pressing
in basic display status, and only take HIAL and HdAL as field
