the function.

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 (8 speed), the inverter
operates at the frequency set in Pr.6.
 Input compensation of multi-speed setting (Pr.28)
• Speed (frequency) can be compensated for the multi-speed setting and the remote setting by inputting the frequency
setting compensation signal (terminals 1, 2).
NOTE
• The priority of the frequency commands given by the external signals are as follows: 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
• 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.
• When performing analog input compensation, set Pr.28 Multi-speed input compensation selection to "1".
• Select the terminals (terminals 1, 2) to use for compensation input voltage (0 to ± 5 V, 0 to ± 10 V) at Pr.73 Analog input
selection.
• When using terminal 1 for compensation input, set Pr.868 Terminal 1 function assignment = "0 (initial value)".
• 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.
