Channel 1 Interface X7

NAVIGATION: encoder > X7_ (eg_SinCos_Channel1) > Channel 1 Interface X7

SinCos encoders can be used to evaluate high-resolution encoders. A track signal period is interpolated at a 14-bit resolution (fine interpolation).

Parameters

P. no.	Settings	Function
P 0505	ENC_CH1_Sel	Configuration of the incremental interface
(0)	OFF	No evaluation
(1)	SinCos	High-resolution SinCos encoder ( 1 Vss) with fine interpolation
(3)	TTL	TTL encoder with zero pulse
P 0540	ENC_CH1_Abs	Determining protocol type: When starting the device and after changing the encoder parameters, the absolute position of an incremental measuring system is read out via a digital interface.
(0)	OFF	No evaluation
(1)	SSI	Serial communication to Heidenhain SSI protocol
(2)	EnDat	To Heidenhain EnDat protocol ⁽¹⁾
(3)	Hiperface	To Stegmann-Hiperface protocol ⁽¹⁾
(4)	SSI_Cont	SSI (1ms clock)
P 0542	ENC_CH1_lines	Setting of incremental pulses per revolution (value range 1 - 65536)
P 0543	ENC_CH1_Multi	Number of multi-turn bits
P 0544	ENC_CH1_Single	Number of single-turn bits
P 0545	ENC_CH1_Code	Selection of coding: Gray/binary
P 0551	ENC_CH1_EncObsMin	Amplitude monitoring
P 0555	ENC_CH1_Info	Encoder name
P 0556	ENC_CH1_EncObsAct	Amplitude of analog signal
¹⁾ With EnDat and Hiperface the information on single-turn and multi-turn, coding and pulses per revolution is read automatically from the encoder (device must detect encoder product ID).
