Operation Mode Setting
Apply two types of operation modes and switch between them as required. For both the first
and second command source, set the frequency after shifting operation commands to the
multi-function input terminal. Mode swiching can be used to stop remote control during an
operation using the communication option and to switch operation mode to operate via the
local panel, or to operate the inverter from another remote control location.
Select one of the multi-function terminals from codes In. 65–71 and set the parameter value
to 15 (2nd Source).

If signals are provided to the multi-function terminal set as the 2
nd
command source (2nd Source), the operation can be performed using
the set values from bA.04-05 instead of the set values from the drv and
Frq codes in the Operation group.
The 2nd command source settings cannot be changed while operating
with the 1
st
command source (Main Source).
• When setting the multi-function terminal to the 2
nd
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 2
nd
command. Before shifting input to the multi-function
terminal, ensure that the 2
nd
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.
