The interface electronics from Heidenhain adapt the encoder
signals to the interface of the
subsequent electronics. They are used when the
subsequent electronics cannot
directly process the output signals from
Heidenhain encoders, or
if additional interpolation of the signals is
necessary.
Input signals of the interface electronics
Interface electronics from Heidenhain can be connected to incremental encoders with sinusoidal signals of 1 VPP (voltage signals) or 11 µAPP (current signals). The IK 220 PC expansion board can also process EnDat and SSI.
Interpolation of the sinusoidal input signals In addition to being converted, the sinusoidal encoder signals are also interpolated in the interface electronics. This results in finer measuring steps, leading to an increased positioning accuracy and higher control quality.
Formation of a position value
Some interface electronics have an integrated counting function. Starting from the last reference point set, an absolute position value is formed when the reference mark is traversed, and is output to the subsequent electronics.
Output signals of the interface electronics
Interface electronics with the following interfaces to the subsequent electronics are available:
