Maximum frequency

When I tried to change the maximum frequency (Pr.1), "Er4" occurred and the value could not be changed.

If you try to change a parameter in other than the PU operation mode, the mode specification error "Er4" may occur.

Set the parameters in the PU operation mode or set Pr.77 (Parameter write selection) to "2" to set the parameter in any operation mode.
