Loader link function (Mode selection)
Function code to switch the links to the inverter supporting loader software (FRENIC Loader). Rewriting y99 with
the inverter supporting loader software (FRENIC Loader) enables the frequency command and operation
command from the inverter supporting loader software (FRENIC Loader). You do not need to use the keypad since
the data is rewritten from the inverter supporting loader.
If the operation command is configured to be given from the inverter supporting loader software, and if the
computer starts to go out of control during the operation and a stop command from the loader software is ignored,
remove the communication cable connected to the computer that runs the inverter supporting loader software, and
connect the keypad to set the y99 data to 0. By setting the y99 data to 0, the operation is isolated from the inverter
supporting loader software's commands, switching to the commands of inverter's own settings (such as function
code H30).
The y99 data is not saved in the inverter; the setting is lost and returned to 0 when powered off.
