Page 5: Overview
Overview Overview Introduction The stepper motor control SMCI35 is an extremely compact and cost-effective constant current power output stage with integrated Closed-Loop current control. Due to the great capacity and functions available, it offers designers and developers a rapid and simple method of resolving numerous drive requirements with less programming effort. - Page 6 Technical manual SMCI35 Overview With the integrated NanoJ programming language based on the Java standard, complete sequencing programs can be implemented that can be run autonomously without a superordinate controller. The programs can be created, compiled directly and written to the controller with the free NanoJEasy editor.

Page 14: Encoder Connection: Connector X2
Technical manual SMCI35 Connections and circuits Encoder connection: Connector X2 Optional encoder An optional encoder can be connected to the stepper motor control. By default, the closed-loop control for a three-channel encoder is set up with 500 pulses/revolution in a 1.8° stepper motor. With an 0.9° stepper motor, you should use an encoder with 1000 pulses/revolution to achieve the same control quality. -
