1. Introductions and Features
1.1 Introductions
The ISC02/04/08 is a microprocessor embedded, voltage control, miniature stepper motor controller. It is
integrally designed to fit onto stepper motors, and is simple to control. With ISC02/04/08, the motor speed can
be controlled by an analog voltage. It is simple, stable and low cost. ISC02 can provide 0 - 2A adjustable phase
current through 10 ~ 28VDC input voltage. ISC04 can provide 1. 5 - 4A adjustable phase current through 12 ~
40VDC input voltage. ISC08 can provide 3 - 8A adjustable phase current through 12 ~ 40VDC input voltage.
The microprocessor of the ISC02/04/08 is capable to ramp up the current speed to the desired speed. It is
possible to jump to 1250 rpm in 0. 3 seconds. This feature makes the sudden increase of the desired speed
become possible. With the ISC02/04/08, the motor speed can be controlled by an external potentiometer.
ISC02/04/08 driver can run the motor without user control device. At the same time, with the high-speed current
compensation function, ISC02/04/08 can compensate the effects caused by counter electromotive force, which
is produced in high- speed motor turning.
ISC02/04/08 can be mounted onto NEMA 17 / 23 series stepper motor seamlessly through adapting flanges. The
enclosure is made of die-cast aluminum which provides a rugged durable protection and improves the heat
dissipation.
