Description
The 3540M step motor driver is a microstepping
drive from 400 to 12,800 steps per revolution, with
custom resolutions available upon request, step
phase sequencer with MOSFET three state switch-
ing 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 dis-
abled. Additional there is a switch selectable self-
test which rotates the motor 1
/2
revolution in each
direction at 100 steps/second.
The amplifier regulates motor current by chopping at
a constant, inaudible frequency. Phase current is se-
lected from 32 levels by a DIP switch. Microstepping
resolution is also selected by DIP switch.
