7.4 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.
