Setting method Set "8" in Pr. 79 "operation mode selection".
External signal-based opera- The input signal RH is assigned as the external signal-based
tion mode switching signal operation mode switching signal. (When "8" is set in Pr. 79, RH
automatically operates as the external signal-based operation
mode switching signal.)
Functions
In the external signal-based operation mode switching mode,
the following functions are made valid:
Set
Value
I 1
t is connected

the external operation
I
1 8
Connection of RH and SD in the PU operation mode forces the
inverter to switch to the external operation mode. Disconnection
of RH and SD switches the inverter to the PU operation mode.
Note that this switching can be done only during an inverter stop

and cannot be done diring operation.

Note: 1. Setting "8" in Pr. 79 changes the function of terminal
RH (three-speed setting (high speed)) to the opera-
tion mode switching function. At this time, the function
of terminal RH (three-speed setting (high speed)) is
invalid.
2. This function is not available for the FR-PUO1 E para-
meter unit.
