Speed setting by external terminals
(2) Multi-speed setting for 4 or more speeds (Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
Speed from 4th speed to 15th speed can be set according to the combination of the RH, RM, RL and REX signals. Set the
running speeds in Pr. 24 to Pr. 27, Pr. 232 to Pr. 239 (In the initial value setting, 4th speed to 15th speed are invalid).
For the terminal used for REX signal input, set "8" in any of Pr. 178 to Pr. 182 (input terminal function selection) to assign the
function.

When "9999" is set in Pr. 232 Multi-speed setting (speed 8), operation is performed at
speed set in Pr. 6 when RH, RM and RL are turned OFF and REX is turned ON.
REMARKS
 The priorities of the speed commands by the external signals are "Jog operation > multi-speed operation > terminal 4 analog input
> terminal 2 analog input".
(Refer to page 152 for the speed 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. 182 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
