 Multi-speed setting for 4th speed or more (Pr.24 to Pr.27, Pr.232 to
Pr.239)
• The frequency from 4th speed to 15th speed can be set by 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 status, 4th to 15th speeds 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.

*1 When RH, RM and RL is set to OFF and REX is set to ON when "9999" is set to Pr.232 Multi-speed setting (speed 8), the inverter runs by the
frequency set to Pr.6.
 Direct multi-speed setting
• While the RLF or RLR signal is input, the operation is according to Pr.6 Multi-speed setting (low speed). The rotation is
forward while the RLF signal is input, and the rotation is reverse while the RLR signal is input.
Low-speed forward rotation command
Low-speed reverse rotation command
NOTE
• The Pr.6 setting should be equal to or higher than the Pr.13 Starting frequency setting.
• To assign the RLF and RLR signals to input terminals, set "128 (RLF)" and "129 (RLR)" in any two parameters from Pr.178
to Pr.189 (Input terminal function selection).
• The direct multi-speed operation is enabled when the inverter operates in External operation mode or External/PU
combined operation mode 1.
• When the RLR or STR signal is input while the RLF signal is input, the motor is decelerated to stop.
• When the RLF or STF signal is input while the RLR signal is input, the motor is decelerated to stop.
• When Pr.59 Remote function selection ≠ "0", the RLF signal is used as the STF signal, and the RLR signal is used as
the STR signal.
