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.
