Setting examples of customizable logic
Setting example 1: Use one switch to change multiple signals
If you use one switch to change the frequency setting 2/frequency setting 1 and torque limit 2/torque limit 1
simultaneously, replace an external circuit that is conventionally needed with a customizable logic reducing the
general-purpose input terminals used to a single terminal.
To configure this customizable logic, set the function codes as follows. (Timer selection) and (Timer setting) do not
need to be modified if no change is made.
