Multi-speed setting for 4 or more speeds (Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
Frequency from 4 speed to 15 speed 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. 184 (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 > terminal 2 analog input".
(Refer to page 174 for the frequency command by analog input)
Valid in the 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 Pr. 59 Remote function selection ≠ "0", multi-speed setting is invalid as RH, RM and RL signals are remote setting signals.
NOTE
Changing the terminal assignment using Pr. 178 to Pr. 184 (input terminal function selection) may affect the other
functions. Make setting after confirming the function of each terminal.
