Description

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 amplifiers

and optoisolated circuits. The drive also includes

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.
