4.7.1 Operation by multi-speed 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 Extended function display selection = "0". (Refer to page 197)

Performing IPM parameter initialization changes the settings. (Refer to page 85)

 The inverter operates at frequencies set in Pr. 4 when RH signal is ON, Pr. 5 when RM signal is ON and Pr. 6 when RL
signal is ON.
 For the RL signal, set "0" in any of Pr.178 to Pr.182 (input terminal function selection) to assign the function to a terminal.

REMARKS

In the initial setting, if two or three of multi-speed settings 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 and RM signals are assigned to the terminals RH and RM in the initial setting. By setting "1 (RM)" or "2 (RH)" in any of
Pr. 178 to Pr. 182 (input terminal function selection) , you can assign the signals to other terminals.
