The function parameters of the VFD are divided into groups by function. Among the function parameter groups, the P98 group is the analog input and output calibration group, while the P99 group contains the factory function parameters, which are user inaccessible. Each group includes several function codes (each function code identifies a function parameter). A three-level menu style is applied to function codes. For example, "P08.08" indicates the 8th function code in the P08 group.
The function group numbers correspond to the level-1 menus, the function codes correspond to the level-2 menus, and the function parameters correspond to the level-3 menus.
1. The content of the function code table is as follows:
Column 1 "Function code ": Code of the function group and parameter
Column 2 "Name": Full name of the function parameter
Column 3 "Description": Detailed description of the function parameter
Column 4 "Default": Initial value set in factory
Column 5 "Modify": Whether the function parameter can be modified, and conditions for the modification
"○" indicates that the value of the parameter can be modified when the VFD is in stopped or running state.
"◎" indicates that the value of the parameter cannot be modified when the VFD is in running state.
"●" indicates that the value of the parameter is detected and recorded, and cannot be modified.
(The VFD automatically checks and constrains the modification of parameters, which helps prevent incorrect modifications.)
2. The parameters adopt the decimal system (DEC). If the hexadecimal system is adopted, all bits are mutually independent on data during parameter editing, and the setting ranges at some bits can be hexadecimal (0–F).
3. "Default" indicates the factory setting of the function parameter. If the value of the parameter is detected or recorded, the value cannot be restored to the factory setting.
4. To better protect parameters, the VFD provides the password protection function. After a password is set (that is, P07.00 is set to a non-zero value), "0.0.0.0.0" is displayed when you press the PRG/ESC key to enter the function code editing interface. You need to enter the correct user password to enter the interface. For the factory parameters, you need to enter the correct factory password to enter the interface. (You are not advised to modify the factory parameters. Incorrect parameter setting may cause operation exceptions or even damage to the VFD.) If password protection is not in locked state, you can change the password any time. You can set P07.00 to 0 to cancel the user password. When P07.00 is set to a non-zero value during power-on, parameters are prevented from being modified by using the user password function. When you modify function parameters through serial communication, the user password protection function is also applicable and compliant with the same rule.
