The Encoder Emulator is a multi-channel Sercos to Quadrature Encoder output generator. The Encoder Emulator receives a digital position command from the Sercos network and generates A, B & I pulse train accordingly. The Encoder Emulator incorporates a proprietary Integral linear interpolation for achieving a smooth pulse rate. Maximum update rate 250 µSec, maximum output pulse frequency 5 MHz. Typical uses: triggering an ink-jet printing head or an ultrasonic module according to 3D trajectory data or generate command to pulse & direction low cost servo drives used as service axes in a machine. The Multi-Channel Encoder Emulator is connected to the Sercos system as a slave. The real-time channel is used for cyclic data and the service channel is used for configuration.
