The programmable interpolation unit IPE4k is intended for connection to incremental position and angle measuring systems with sinusoidal input signals that are phase-shifted by 90 °. It can be operated on a large number of encoder systems that work according to the most varied of measuring principles. The IPE4k realizes a subdivision of the signal periods up to 4096-fold. The interpolation unit works with both single-ended and differential input signals. The configuration can be done via the EEPROM or via USB. It is also possible to equip the unit with a serial interface and / or an active current / voltage converter.
An AMAC-specific gain and offset control as well as the possibility of a phase correction of the internal AM-IP4k guarantee a high measuring accuracy under industrial conditions.
The unit can be connected to a standard meter or controller via the RS422 interface. The internal operating voltage is 5 VDC. The functions of the interpolation circuit AM-IP4k such as switchable analog filters or digital hysteresis make the unit ideal for use in control systems.
