The AIS-42MA is an advanced stepper motor module manufactured by Autonics. It is a two-phase, bipolar, servo drive with an integrated encoder. The module comes equipped with a maximum output of 60 watts, allowing for high torque and accuracy. Additionally, it features automatic current control, dynamic torque control for higher speed operation, and velocity feed forward control for improved response. Furthermore, the module comes with adjustable microstepping resolutions of up to 512 steps per revolution and the ability to run continuous or one-revolution-per-turn motions. With its high resolution encoders, this module offers excellent feedback to ensure precise positioning and speed without missing any steps.
