LS-173AF is a single-axis 14-bit analog feedback motion controller with integrated servo amplifier designed for applications using brushless or brush-commutated motors up to 1 HP. Trapezoidal brushless motor commutation is performed. Up to 31 intelligent servo drives can be controlled over a multi-drop full duplex RS-485 network in a distributed motion control environment. Standard RJ-45 connectors and commercially available cables are used for daisy chaining of the modules. LS-173AF is equipped with various safety features for the motor and amplifier such as short circuit protection, over travel limit, hardware stop input, over and under voltage shutdown. The maximum motor output current can be limited by setting of dipswitches or by software.
