Y-encoder

The following data are typical guidelines and can therefore deviate for the specific motor.

Encoder type	Technical description	Manufacturer / designation

Y	Absolute encoder ( ) Singleturn ( ) Multiturn ( ) Digital ( )	Sick Stegmann singleturn: EKS 36 EFS 50 multiturn: EKM 36 EFM 50
	Resolution: 17 / 20 / 23 bit/revolution
	Measuring principle: optical ( )
	Protocol: Hiperface DSL
	Electronic type plate ( )

Output signal

The Hiperface DSL protocol transmits digital data between an encoder and the drive controller by modulating the data into the supply line of the encoder. The absolute positions are send serial and cyclic synchronous from the encoder triggered by the trigger signal of the drive controller.
