HEIDENHAIN Encoders With Fanuc Interface
SCHAUMBURG, IL -- (Marketwired) -- 04/18/13 -- 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
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.
The ROC/ROQ 400F rotary encoders with separate shaft coupling are
available with a synchro flange or clamping flange, and have integral
bearings and a solid shaft. The shaft coupling compensates axial
motion and misalignment (radial and angular offset) between the
encoder shaft and measured shaft. This relieves the encoder bearing
of additional external loads that would otherwise shorten its service
life. Diaphragm and metal bellows couplings designed to connect the
rotor of the ROC/ROQ 400F encoders are available.
The singleturn encoder versions of the 400 Series have a revolution
counter that saves the number of revolutions during operation. After
power is switched off, the counter is reset to zero. The multiturn
versions feature an integral gear box, which keeps track of
revolutions and is not affected by power loss. That absolute position
is available immediately upon switch-on.
All HEIDENHAIN's 400 Series encoders are mounted with IP 67
protection on the housing and IP 64 at the shaft inlet.
