Prohibiting Overwriting of Parameters
If A1-01 is set to 0, all parameters except A1-01 and A1-04 are write protected, U1- †† , U2- †† and
U3- †† will be displayed. If A1-01 is set to 1, only the parameters A1-01, A1-04 and A2- †† can be read or
written, U1- †† , U2- †† and U3- †† will be displayed. All other parameters will not be displayed.
If you set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selection) to 1B
(write parameters permitted), parameters can be written from the digital operator when the terminal that has
been set is ON. When the set terminal is OFF, writing parameters other than the frequency reference is prohib-
ited. However, the parameters can be read.
