Description
LS-182SE is a single-axis motion controller with
integrated servo amplifier designed for applications
using brushless (AC) or brush-commutated (DC)
motors, equipped with differential or single ended
encoder, up to 1 HP. Trapezoidal brushless motor
commutation is performed automatically if hall
sensors are connected to the unit.
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-182SE is equipped with various safety features
such as short circuit protection for the motor and
controller, over travel limit switch inputs, emergency
stop input, over and under voltage shutdown. The
maximum motor output current and overload time
can be set.
