Interpolation unit IPE2000

IPE2000 low

The programmable interpolation unit IPE2000 - USB is intended for connection to incremental position and angle measuring systems with sinusoidal input signals phase-shifted by 90 °. It can be used on a large number of encoder systems that work according to a wide variety of measuring principles,
operate. The IPE2000 - USB realizes a subdivision of the signal periods up to 2048-fold. The interpolation unit works with both single-ended and differential input signals. The configuration can be done via the EEPROM or via USB. The
Possibility 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 phase correction of the internal GC-IP2000 guarantee a high measurement 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 GC-IP2000, such as switchable analog filters or digital hysteresis, make the unit ideal for use in control systems.
