2 2 Bosch Rexroth AG Electric Drives and Controls Position detection via absolute encoders with SSI interface Encoder resolution up to 56 bit Transmission frequency up to 2 MHz Gray or binary code Rotation direction reversal Current and voltage measuring ranges Saved device nameplate Diagnostic and status indicators Documentation Data sheet Application description This module is designed for use within an IndraControl S20 station. It is used to detect positions by absolute encoder with SSI interface. An analog output, which serves to specify the command value for a drive control, for example, can be used at the same time.
