4.5 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) and 9 (Speed-H) are recognized as binary
commands and work in combination with Fx or Rx run commands. The inverter operates
according to the frequencies set with BAS-50
–56 (multi-step frequency 1–7) and the binary
command combinations.
