LPKF SMCUII

The SMCU II is a motor controller for highly synchronous path control of two axes. DC, 2- and 3-phase servo, stepper and linear motors can be connected. Powerful algorithms and high sampling rates guarantee high quality control. The SMCU II can be expanded by up to three DAC1005 axis controllers on a local CAN bus so that up to five axes can be controlled on one path. The interfaces for limit switches, digital and analog inputs and outputs, and encoders (optional) are integrated. Communication with the Master PC is done via the serial port (RS232) using our VisualControl®-API. Installation and start up, and parameterization are done with the LPKF MotionTools.
