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 with the Frq code in the Operation group.
The digital input terminals can be programmed to provide fixed speed inputs (multi-step
frequencies). Parameters in the Input Group, In.65 through In.71 can be assigned 7 (Speed-L), 8
(Speed-M) and 9 (Speed-H). The step frequencies are set using parameters St1 through St3 (multi-
step frequencies 1 through 3) in the Operations Group. The digital inputs are recognized as a 3 bit
binary input. Additional speeds are set with parameters bA.53–56 (multi-step frequencies 4–7).

EX: Using terminals P3, P4 and P5 set to Speed-L, Speed-M and Speed-H
respectively, the following multi-step operation will be available.
