LS-131 is all digital single axis servo controller with integrated power amplifier designed for applications requiring sinusoidal control of Rotary or Linear brushless motors up to 1.5 HP. LS-131 supports coordinated motion of several motors. 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-131 is equipped with various safety features such as short circuit protection for the motor and amplifier, limit switch inputs, hardware stop input, over/under voltage shutdown and encoder presence control. The maximum motor output current and overload time can be limited by software.
