When setting the multi-function terminal to the 2nd command source (2nd Source) and
input (On) the signal, operation state is changed because the frequency setting and the
Operation command will be changed to the 2nd command. Before shifting input to the multi-
function terminal, ensure that the 2nd command is correctly set. Note that if the deceleration
time is too short or inertia of the load is too high, an overvoltage fault trip may occur.

Depending on the parameter settings, the inverter may stop operating when you switch the
command modes.
