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

www.ICHmo.com www.ICHmotion.com Page 6 of 18 CI-REV-I Function Description Supply Voltage CI240 controllers accept a wide range input voltage from 12 to 40VDC. (CI240-2A accepts 10~35VDC) In general, higher supply voltage improves motor performance under high speed situation, but also increases the power loss and temperature raise. Adjust Output Current CI240-2A / CI240-4A / CI240-8A are capable of providing 2A / 4A / 8A per phase maximum output current respectively. In specific application, the peak output current needs to be adjusted to meet the rated motor current. A trimmer...
