The PMX-4EX-SA model is manufactured by Arcus Technology, and is a 4-axis controller which has a USB 2.0 and RS-485 communication. It has a 6M maximum pulse rate with available acceleration in either trapezoidal or s-curve.
There is a continuous linear coordinated buffered XYZ move, which has a XY circular and arc coordinated motion. It has a single-ended or differential quadrature encoder inputs per axis with in-built joystick control for XYZU axis. It also utilizes BASIC-like standalone programming language, which is supported by multi-task programming with stepnloop shuttered loop algorithm.
