Interpolation unit IPE40

amac logo v4 dunkel

The interpolation unit (IPE40) is used to increase the resolution of incremental distance and angle measuring systems with sinusoidal output signals that are phase-shifted by 90 °. It is suitable for sensors with a standardized voltage or current interface. An adjustable minimum edge distance at the output as well as the programmable analog and digital hysteresis enable use even with impaired input signals.
