Description
LS-173AP is a single-axis absolute positioning
motion controller with integrated servo amplifier
designed for applications using brushless (AC) or
brush-commutated (DC) motors up to 1 HP. No
jumpers or setup is required to switch between both
types of motors. Trapezoidal brushless motor
commutation is performed automatically if hall
sensors are connected to the unit.
Up to 32 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-173AP is equipped with various safety features
such as short circuit protection for the motor and
amplifier, emergency stop input, over and under
voltage shutdown. The maximum motor output
current can be limited by setting of dipswitches.
