Description
CI240 Miniature Stepper Motor Controller is a series of miniature, high performance stepper motor controller.
They can be mounted onto H42 / H57 / H86 / H110 (NEMA17, NEMA23, NEMA34, NEMA42) series stepper
motor seamlessly through corresponding flanges. The thickness of these controllers is less than 14 mm.
CI240-2A is capable to provide 0-2A adjustable current, 10~35VDC
CI240-4A is capable for 1.6-4A adjustable current output , 12~40VDC
CI240-8A is capable for 2A-8A adjustable current, 12~40VDC
Their mixed-decay current control reduces the back-EMF effect under high motor speed and improves the
performance. The cover is made of die-cast aluminum which provides a rugged durable protection and
improves the heat dissipation
Optically Isolated Input Interface
CI240xx controllers’ logic control inputs are all optically isolated. All opto-couplers share one common anode
(Vcc) as shown in above schematic diagram. Typically, Vcc is 5V. However, 3.3V or voltages higher than 5V are
also acceptable, so long as the current through the opto-coupler’s emitter is between 5~20mA
Should a voltage higher than 5V be applied to Vcc, an additional resistor is needed for every terminal to ensure
that the current through each emitter does not exceed 20mA
