PARAMETERS

4.2.35 Parameter write inhibit selection (Pr. 77)

Pr. 77 "parameter write disable selection" Related parameters

Pr. 79 "operation mode selection"

You can select between write-enable and disable for parameters. This function is used to prevent parameter values from being rewritten by accident.

Pr. 77 Setting Function

0Write enabled during a stop only.

Parameter values may only be written during a stop in the PU operation mode. (Note 1)

1Write disabled.

Values of Pr. 22, Pr. 75, Pr. 77 and Pr. 79 "operation mode selection" can be written.

2Write enabled even during operation.

Note: 1. The values of the parameters half-tone screened in "4.1.1 Parameter list" can be set at any time. (Pr. 72 and Pr. 240 values cannot be set during external operation.)

2.If Pr. 77 = "2", the values of the following parameters cannot be written during operation. Stop operation when changing their parameter settings.
