All signals will be ON with the rated speed reference set in C1-26 if the 12-bit binary setting is selected.
D
If the 3- or 2-digit BCD setting is selected, a rated speed reference of 999 or 99 will be set in C1-26
respectively.
The input signal circuit for digital speed references is the same as the sequence input signal circuit explained
in 3.4.4 Sequence Input Signal Circuit (for Stand-alone Drive).
