Epson LX-810 Technical Manual

REV.-A
In the case of 1-2 phase excitation:
Figure 2-30 shows the excitation signal input circuit. When the Td terminal is LOW, the SLA702M can
cut off the output current. By using this function, the unaltered 2-phase excitation signal can cause the
1-2 phase excitation to be on
3/8ths of the time, which is a suitable value.
Figure 2-31 shows the timing chart.
