 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 according to the combination of the RH, RM, RL, and REX signals.
Set the frequencies in Pr.24 to Pr.27, Pr.232 to Pr.239. (In the initial status, 4th to 15th speeds are invalid.)
• To input the REX signal, set "8" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function.

*1 When the RH, RM and RL signals are OFF and the REX signal is ON while "9999" is set to Pr.232 Multi-speed setting (speed 8), the inverter
operates at the frequency set in Pr.6.
NOTE
• The priority of the frequency commands given by the external signals are as follows: JOG operation > multi-speed operation
> terminal 4 analog input > terminal 2 analog input. (For details on frequency commands given by analog input, refer to
358.)
• The input compensation of multi-speed setting is enabled when the inverter is in the External operation mode or PU/External
combined operation mode (Pr.79 = "3 or 4").
• Multi-speed parameters can also be set during PU operation or External operation.
• The Pr.24 to Pr.27 and Pr.232 to Pr.239 settings have no priority among them.
• When Pr.59 Remote function selection ≠ "0", the multi-speed setting is invalid since the RH, RM, and RL signals are for
remote setting.
• 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.
