InterfacesPostition values
The EnDat-Interface is a digital, bi- directional Interface for measuring systems. With this interface you can read out position values and in the measuring system saved informations. This values can also be updated or new values can be saved. Due to the serial data transfer four signal wires are enought. The Data DATA gets transferred synchroniously to the from the subsequent electronics given clock frequency CLOCK. The selection from the mode of transmission (position values, pa-rameter, diagnostics,...) is done with mode- commands which are sent from the subsequent electronics to the measuring system.
Order Code Instruction Set Incremental signals
EnDat22 EnDat 2.2 Without
The clock frequency is variable - depending on the cable length (max. 100m). With propagation electronics, either clock frequencies up to 16 MHz are possible or cable length up to 100m. For EnDat encoders the maximum clock frequency is stored in the encoder memory.Propagation-delay compensation is provided for EnDat 22.
Transmission frequencies up to 16MHz in combination with large cable length place high technological demands on the cable.Greater cable lengths can be realized with an adapter cable no longer than 6m and an extension cable.As a rule, the entire transmission path must be designed for the respective clock frequency.

InterfacesSSI + »1Vpp
SSI Interface is an unidirectional Interface which can output position values.The Data DATA gets transferred synchroniously to the from the subsequent electronics given Clock frequency CLOCK.Additionaly three special Bits (Error, War-ning and Parity) will be transferred.
AMO-measuring systems with » 1-Vpp-Interface are outputing signals which can be highly interpolated.
The sine shaped incremental signals A and B are electrically 90° phase shifted and have a signal strength from 1Vpp. The showed sequence of the outputed signals - B after A - is valid for the in the connection drawing stated movement direction.
