SinCos encoders and SinCos absolute value encoders with Hiperface
Features
Input/output frequency:
0 ... 200 kHz
Internal resistance (R
i
):
221
W
Offset voltage for signals SIN, COS, Z:
2.5 V
ƒ
The differential voltage between signal track and reference track must
not exceed 1 V
± 10 %.
ƒ
The connection is open−circuit monitored (fault message "Sd8")
ƒ
For encoders with tracks sine, sine and cosine, cosine:
–
Assign RefSIN with sine.
–
Assign RefCOS with cosine.
ƒ
For SinCos absolute value encoders with Hiperface, the serial interface (RS
485) is available instead of the zero track (Z track).
