Using Multi-step Speed Reference
Allocate one of the Multi-function Input S1 to S7 Selection (C001 to C007) to 02 to 05 or 32 to 38
(Multi-step speed) and turn ON that terminal. This enables the inverter to perform multi-step speed
operation, independent of Frequency Reference Selection (A001/A201) settings.
The frequency depends on the value set in the Multi-step Speed Reference 1 to 15 (A021 to A035).
However, at the 0th speed where multi-step input signals are all OFF, the frequency depends on the
1st/2nd Frequency Reference Selection (A001/A002) setting.

*1. Only the frequency reference at the 0th speed depends on the 1st/2nd Frequency Reference Selection
(A001/A002) setting.
*2. To enable the switching to the 2nd control, allocate one of the Multi-function Input Terminal S1 to S7 Selection
(C001 to C007) to 08 (SET) and turn ON that terminal.
