4.11.1 Multi-speed setting operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write

(1) Multi-speed setting (Pr. 4 to Pr. 6)
⋅
Operation is performed at the frequency set in Pr. 4 when the RH
signal turns on, Pr. 5 when the RM signal turns on, and Pr. 6 when the
RL signal turns on.
(2) Multi-speed setting higher than speed 4 (Pr. 24 to Pr. 27,
Pr. 232 to Pr. 239)
⋅
Frequency from speed 4 to speed 15 can be set according to the
combination of the RH, RM, RL and REX signals. Set the running
frequencies in
Pr. 24 to Pr. 27, Pr. 232 to Pr. 239 . (In the initial value
setting, speed 4 to speed 15 are unavailable.).
⋅
For the terminal used for REX signal input, set "8" in any of Pr. 178 to
Pr. 189 (input terminal function selection) to assign the function.
* When
"
9999
"
is set in Pr. 232 Multi-speed setting (speed 8) , operation is performed at
frequency set in Pr. 6 when RH, RM and RL are turned off and REX is turned on .

REMARKS
⋅
In the initial setting, if two or three speeds are simultaneously
selected, priority is given to the set frequency of the lower signal. For
example, when the RH and RM signals turn on, the RM signal
(Pr. 5)
has a higher priority.
⋅
The RH, RM, RL signals are assigned to the terminal RH, RM, RL in
the initial setting.
By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of
Pr.178 to Pr.189 (input
terminal function assignment) , the signals can be assigned to other
terminals.
