Accessory 51E
30 Hiperface Interface Option
HIPERFACE INTERFACE OPTION (OPT2)
The Hiperface interface option is designed to operate the digital portion of SINCOS and SINCODER
devices from Stegmann Corporation. The High Resolution Interpolator with Hiperface option supports
commands that apply to the motion needs of PMAC products. These commands include absolute
position, encoder temperature, sine-output mux (sincoder), index on RS485 lines (sincoder), encoder
reset, error status, and encoder type.
SINCOS Encoders
SINCOS encoders from Stegmann Corp. use a microcontroller inside their encoders to provide a serial
link, which is capable of transferring data to and from the encoder without affecting the sinusoidal output.
Depending upon the model of encoder, different parameters pertaining to absolute position (single or
multi-turn), encoder temperature, encoder type, and presence of encoder may be determined.
Absolute position is returned with a resolution of 16,384 counts per revolution in the SCS/SCM 60 and
SCS/SCM 70 encoders.
The SCM 60 and SCM 70 models are capable of multi-turn absolute position reporting of up to 4096
revolutions of 16,384 steps per revolution. They have absolute position counters that roll over at
67,108,864 counts.
The SCS 60 and SCS 70 models are capable of single-turn absolute position reporting of 16,384 steps per
revolution. They have absolute position counters that roll over at 16,384 counts.
Note:
An application for the SINCOS Hiperface interface option is PMAC’s power-on
position for establishing the commutation position in brushless servomotors. This
application uses the SINCOS encoder models in single-turn configuration.
SINCODER Encoders
SINCODER encoders from Stegmann Corp. also use a microcontroller inside their encoders to provide a
serial link, which is capable of obtaining data from the encoder without affecting the sinusoidal output.
Parameters pertaining to encoder type and presence of encoder may be determined on a SINCODER.
SINCODERs are also capable of changing the type of sinusoidal outputs that they provide. The power-up
default output resolution is typically 1024 sine cycles per revolution. The SINCODER is capable of
being switched into a mode that outputs one sine cycle per revolution.
The serial data line may be set to output the index pulse from the sincoder. This output, when selected,
sets the RS485 digital output until the index mark is reached. The RS485 line drops low when the index
pulse is reached inside the encoder.
