4.6 Frequency setting by external terminals
4.6.1 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 selection .
*
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
(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.

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)
, you can assign the signals to
other terminals.
