New encoders are the LC 183 and 483 series with EnDat interface and LC 193 and 493 with FANUC interface. The encoders are said to make purely serial axis-control possible. The resolution of the absolute position value is 5 nm for encoders with an accuracy grade of ±3 µm, and 10 nm for encoders with an accuracy grade ±5 µm with the EnDat versions. Also regardless of the measuring length, the data word length is 32 bits and with a clock frequency of 8 MHz, the formation of the position value and transfer takes approximately 20 µs. Both output formats also incorporate the single-field scanning technique insuring optimum signal quality, high traversing speed and contamination resistance. Maximum cable runs have also increased with the new interfaces.
