The 7080 step motor driver is a microstepping drive
from 200 to 50,800 steps per revolution, step phase
sequencer with MOSFET three state switching am-
plifiers and optoisolated circuits. The drive also in-
cludes an automatic feature to lower motor current
by 50% anytime the motor is left at rest for more
than one second. This feature can be disabled.
The amplifier regulates motor current by chopping
at a constant, inaudible frequency. Phase current is
selected by a DIP switch. Microstepping resolution
is also selected by DIP switch.
