6 -154 Prohibiting Writing Constants from the Digital OperatorIf you set A1-01 to 0, you can refer to and set the A1 and A2 constant groups, and refer to drive mode, usingthe Digital Operator.If you set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selec-tion) to 1B (write constants permitted), you can write constants from the digital operator when the terminalthat has been set is ON. When the set terminal is OFF, writing constants other than the frequency reference isprohibited. You can, however, reference constants. Setting a PasswordWhen a password is set in A1-05, if the set values in A1-04 and A1-05 do not match, you cannot refer to orchange the settings of constants A1-01 to A1-03, or A2-01 to A2-32.You can prohibit the setting and referencing of all constants except A1-00 by using the password function incombination with setting A1-01 to 0 (Monitor only).Related ConstantsCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torA1-01 Constantaccess levelUsed to set the constant accesslevel (set/read.)0: Monitoring only(Monitoring drive mode andsetting A1-01 and A1-04.)1: Used to select user constant(Only constants set in A2-01to A2-32 can be read andset.)2: Advanced(Constants can be read andset in both quickprogramming mode andadvanced programming (A)mode.)0 to 2 2 Yes A A A A 101HCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torA1-01 Constantaccess levelUsed to set the constant accesslevel (set/read.)0: Monitoring only(Monitoring drive mode andsetting A1-01 and A1-04.)1: Used to select user constant(Only constants set in A2-01to A2-32 can be read andset.)2: Advanced(Constants can be read andset in both quickprogramming mode andadvanced programming (A)mode.)0 to 2 2 Yes A A A A 101H
