 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 running frequencies in

*1 When the RH, RM and RL signals are OFF and the REX signal is ON while Pr.232 Multi-speed setting (speed 8) = "9999", the inverter runs at
the frequency set in Pr.6.
NOTE
• The priority of the frequency commands given by the external signals are "JOG operation > multi-speed operation > terminal
4 analog input > pulse train input > terminal 2 analog input". (For details on frequency commands given by analog input, refer
to page 134.)
• The multi-speed setting for 4th speed or more is enabled in the External operation mode or PU/External combined operation
mode (when Pr.79 = "3 or 4").
• Multi-speed parameters can also be set during PU operation or External operation.
• The settings of Pr.24 to Pr.27, Pr.232 to Pr.239 are not prioritized.
• When Pr.59 Remote function selection ≠ "0", the multi-speed setting is disabled since the RH, RM, and RL signals are used
for remote setting.
• Use Pr.73 Analog input selection to select the characteristic of terminal 2 (terminal to input compensation voltage (0 to ±5 V
/ 0 to ±10 V)).
• 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.
