MID-7604/7602 Power Drive
For maximum flexibility, you can connect 8-wire stepper motors in either a
series or parallel configuration. Connecting the windings in series as shown
in Figure 18 produces the most torque per amp, but has the disadvantage of
higher inductance and poorer high-speed performance.
series or parallel configuration. Connecting the windings in series as shown
in Figure 18 produces the most torque per amp, but has the disadvantage of
higher inductance and poorer high-speed performance.

Alternatively, you can wire 8-wire stepper motors in parallel as shown in
Figure 19. This configuration produces better high-speed performance but
requires more current to produce rated torque.

requires more current to produce rated torque.
