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 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.

Recommended motors for the 7080 drive:

Size 17

Size 23

Size 34
