Transmitting terminal (1-dimensional) Polarization positoner, 1pcs Movement mode: touching, constant rotating Turn angle range: constant rotating without limitation Speed range: touching, 1°/s ~ 9°/s
constant rotating, 1°/s ~180°/s Position accuracy: 0.05 ° Loading weight: 10Kg Diameter of loading tray: Φ150 Environment condition:0~400C,RH≤95% Positioner's controller is controlled by local or remote
According to the listed specifications and requirements, the design ideas of the positioner are:
a. Positioner's configuration: It adopts U-T framework structure, and the framework is made up of welded steel plate components, which ensure a sufficient strength and stiffness conditions of the components. And it also greatly reduce the moment of inertia of the axises.
b. Dragging device: it adopts Japanese Yaskawa AC servo motor
c. Sensor: it adopts high-precision optical encoder as the angle sensor, in order to achieve high-precision control of the positioner
d. Control program: it adopts PC digital control to achieve full control function. The control system of the positioner contains a control PC, which is a direct control device of the positioner, to achieve high-precision and high frequency control requirements. The control PC, as a man-machine interface, adopts WINDOWS operation system, with a friendly interface, easy for operation and management.
