+To be able to write certain groups of parameters, you must "unlock" them either from the servo drive keypad using <code>AF_unL</code>, or by changing parameter <code>P10-22</code>, which cannot be navigated to by the keypad. You must instead do it over RS-485 or RS-232 via the PC software. The software has an unlock dialog that requires the passwords: the "Primary authority" password is <code>jmc</code> and the "Super authority" password is <code>jmc2018</code>, which allow you to access the <code>P10-xx</code> parameters.
