LS-146 is a single-axis intelligent microstepping controller with integrated amplifier designed for applications using two-phase stepper motors. The drive is a member of Logosol’s distributed motion control network. Up to 31 intelligent microstepping drives can be controlled over a multi-drop full duplex RS-485 network. Standard RJ-45 connectors and commercially available cables are used to connect modules into a network. LS-146 is equipped with various safety features such as short circuit protection for the motor and amplifier, over travel limit switch inputs, stop and home inputs. The maximum motor running/holding current can be programmed in the range of 0.5 to 7A using commands from the host computer.
