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.
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.
Input compensation of multi-speed setting (Pr.28)
• Speed (frequency) compensation can be applied 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 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 by analog input, refer to page
415.)
• Valid 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.
