Controls Motors from 1 to 50 Volts - Interfaces with Any IBM/clone parallel printer port for computer control. Up to 4 boards can be daisy-chained
for control from one printer port.
Higher efficiency than uni-polar controllers. This board provides both computer, and on-board control of 4, 6, and 8 wire stepping motors. It controls motors from 1 to 50 volts @2 amps continuous / 3 amps peak current. The bi-polar controller uses chopped current regulation and back-EMF protection. An on-board switch selects stand-alone or computer controlled operation. It provides CLOCKWISE, COUNTER CLOCKWISE, JOG, SPEED, AND STOP control.
This unit is a current regulating controller. Stepping motors perform most efficiently from operating voltages 2 to 3 times the coil’s rated voltage. The chopped current regulation maintains the manufacturere;s motor specs. (User must select an appropriate value current sensing resistor from an included table, and solder it onto PC board).
Includes BASIC software that demonstrates dual phase and half step control. Accepts CMOS, TTL, or mechanical switch input.Requires two power supplies (not included). A) 5V 200ma logic supply. B) up to 50 volts @ 3.5 amps for stepping motor coils. New.
