Heidenhain’s product range of absolute rotary encoders of the 400 Series are now available with interface to Fanuc controls. These encoders are particularly suitable for use on servo axes and spindles in machine tools, and feature integral bearings and stator or separate shaft couplings. Designed specifically for direct connection to Fanuc controls with α and αi interfaces, these new 400 Series encoders are already established with SSI or EnDat interfaces as other options.
Of Heidenhain’s 400 series, the ECN/EQN 400 rotary encoders with stator couplings are available with a blind-hollow or hollow through-shaft. The stator coupling compensates radial runout and alignment errors without significantly reducing the accuracy. The encoder shaft is directly connected with the shaft to be measured. During angular acceleration of the shaft, the stator coupling must absorb only that torque caused by friction in the bearing.
