Description
The EL5021-0090 SinCos EtherCAT Terminal allows direct connection of a measuring sensor, e.g. a linear measuring scale with sinusoidal voltage output 1 V. PP. The measuring signal is processed, interpolated and made available as a 32 bit value. At the same time, an offset, gain and phase error compensation is carried out. The input frequency for the measuring signal inputs is 250 kHz with a signal period resolution of max. 13 bit. In addition, the reference mark can also be stored as a 32 bit value.
