6.3.2 SinCos absolute value encoder with HIPERFACE® protocol
SinCos absolute value encoders with HIPERFACE® protocol are feedback systems which transmit an
absolute position on request. Moreover, they permanently provide an incremental signal via a
sin/cos evaluation. The analog evaluation of the sin/cos tracks provides for a high resolution.
The absolute position is transmitted via an RS485 data interface with 9600 Baud (standard
value).This bidirectional parameter channel also serves to request and transmit error codes, encoder
data and other information. The analog process data channel is created by a differential
transmission of sin/cos signals. The resolutions of these two information channels are generally not
identical, thus the channels have to be parameterised independently of each other in the controller.
6.3.2.1 Initialisation
A connected SinCos absolute value encoder with HIPERFACE® protocol is initialised in the following
cases:
A. When the device is switched on after the waiting time of approx. 1 s has expired.
B. After the encoder wire breakage has been removed.
In case of an encoder wire breakage, a speed and position detection cannot be carried out
correctly. A renewed initialisation after removing the encoder wire breakage serves to connect
to the correct absolute position.
C. After describing one of the following parameters as the setting has an impact on the internal
scaling of the encoder position:

Note!
If the RS485 cable is interrupted, a communication to the encoder is permanently tried
to be built up. After the maximum initialisation time set in C00430/1 has expired, the
error " Sd7: Error encoder communication " is triggered. This error is cancelled if a
communication could be built up successfully and the encoder initialisation has been
executed.
The selection of an error response in
C00603/4 serves to optionally monitor the
communication between absolute value encoder and controller.
If the monitoring is tripped:
• The error response set in C00603/4 is triggered.
• The " Sd7: Encoder communication error " error message is entered into the logbook.
