6.3 Changing the Displayed Units (Hz↔Rpm)
You can change the units used to display the operational speed of the inverter by setting DRV-
21 (Speed unit selection) to “0 (Hz Display)” or “1 (Rpm Display)”.

6.4 Setting Multi-Step Frequency
Multi-step operations can be carried out by assigning different speeds (or frequencies) to the
Px terminals. Step 0 uses the frequency reference source set at DRV-07. Px terminal parameter
values 7 (Speed-L), 8 (Speed-M), 9 (Speed-H), and 10 (Speed-X) are recognized as binary
commands and work in combination with Fx or Rx run commands. The inverter operates
according to the frequencies set at BAS-50–64 (multi-step frequency 1–15) and the binary
command combinations.
