This parameter offers several functions.
1) The user may reset all parameters to their original factory settings.
2) The user may disable the keypad function.
3) The user may lock the parameters and allow them to be read only.
4) The user may disable the drive from accepting frequency or torque command
changes.
Throughout this manual, there are parameters such as this one, which use a term called
Bit Setting. This is simply the ability to have one parameter conduct multiple functions.

Example 1: Assume the function of Pr. 00-02 is set for “Disable Frequency and Torque
Command changes.” By referring to the above chart, we know Bit 1 is equal to “2”,
because the hex to decimal conversion is (2 ^ the bit = the decimal value). Therefore
2
1
= 2, and the decimal “2”, should be set in Pr. 00-02 to disable the frequency and
torque commands.

Example 2: Assume Pr. 00-02 is set for “Disable Frequency and Torque Command
changes” + “Keypad Disabled”. If we follow what we have learned, “Disable
Frequency and Torque Command changes” must be set to decimal “2”; and “Keypad
Disable” must be set to decimal “4”. The summation of the two decimal numbers gives
us 6. By entering the number 6 in the parameter, both functions are enabled.

A setting of 1 enables the “Parameters are Read Only” feature, but Pr. 00-00~00-23,
continue to be accessed.

If users would like to reset the parameters to original factory-settings, simply set the Pr.
00-02 to “9” or “10”. If a password was entered, this must first be decoded to allow the
parameters to be reset.
