MOTOR DRIVING PHASE SEQUENCES
The L297’s translatorgeneratesphase sequences
for normal drive, wave drive and half step modes.
The state sequences and output waveforms for
these three modes are shown below. In all cases
the translator advanceson the low to high transis-
tion of CLOCK.
Clockwise rotation is indicate;for anticlockwise ro-
tation the sequences are simply reversed RESET
restores the translator to state 1, where ABCD =
0101.
HALF STEP MODE
Half step mode is selectedbya high level on the HALF/FULL input.
NORMALDRIVE MODE
Normal drive mode (also called ”two-phase-on” drive) is selected by a low level on the HALF/FULL input
when the translator is at an odd numbered state (1, 3, 5 or 7). In this mode the INH1 and INH2 outputs
remain high throughout.
