(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
invalid.).
 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
 The priorities of the frequency commands by the external signals are "jog operation > multi-speed operation > terminal 4
analog input > pulse train input > terminal 2 analog input". (Refer to page 299 for the frequency command by analog input)
 Valid in External operation mode or PU/External combined operation mode (Pr. 79 = "3" or "4").
 Multi-speed parameters can also be set in the PU or External operation mode.
 Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settings have no priority between them.
 When a value other than "0" is set in Pr. 59 Remote function selection, the RH, RM and RL signals are used as the remote setting
signals and the multi-speed setting becomes invalid.
 When making analog input compensation, set "1" in Pr. 28 Multi-speed input compensation selection.
CAUTION
 Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
