Description:

The 5560 step motor driver is a microstepping drive from 200 to 12,800 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 from 16 levels by a DIP switch. Microstepping resolution is also selected by DIP switch.
