This parameter is used to change the 4-digit user password for parameter locking.
B310: Parameter Lock
This is user programmable 4-digit password to prevent unintentional parameter change from the
digital operation panel. When programmed, it will not allow the user to change any parameter from
digital operation panel or serial link except Local Set Frequency A101 (or D201), Local Torque
Reference A107, PID Reference Setting C611 and terminal functions. The unit will be shipped
without any password protection. To lock the parameters, first enter your selected 4-digit password
in B309 (Change Password) and then enter any value other than your selected password to B310
(Parameter Lock). The parameters will be locked and cannot be changed (except the set frequency).
Now, to open the lock, enter the selected password to B310 (Parameter Lock). If you have entered
correct password, you will have the access of all parameters. Now you can change the parameters,
even the password. To lock the parameters again follow the same thing.
When someone tries to enter parameter in lock condition, below massage is displayed.

B311: Default value Load
Custom Parameter Save
When set to 111, current parameters will be saved to the non-volatile memory for the future use. This
feature is extremely useful for the custom default.
Custom Parameter Default
When set to 222, all the parameters will be set to custom saved parameters saved using 111.
Default Load as per US standard
When set to 333, default value will be loaded as per the US standard in all the parameters. However,
this will not change the factory setting parameters, user password, C211 to C218 and B202 to B211.
Following parameters will be different than the general default.
A101, A103, B104, D103, D201, D203 = 60.00Hz
B101, B102, D101 = 460V
B105, D104 = 1800rpm
General Default Load
When set to 444, default value will be loaded in all the parameters. However, this will not change the
factory setting parameters, user password, C211 to C218 and B202 to B211.
Fault History Clear
When set to 555, the fault history buffer is cleared. No previous fault code and parameter will be
available.
