LS-180 is a single-axis motion control node with ±10V analog output, designed for applications using a standard servo amplifier. The unit can work in NETWORK or STEP/DIRECTION mode. Up to 31 motion control nodes 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-180 is equipped with various safety features such as an over travel limit switch inputs, emergency stop input, encoder presence control and motor current monitoring.
