Parameter Description
Simulation.UnitsPerRevo- Used to scale the output (see object 0x6001).
lution Value range: 1000-65536.
Higher values provide better position resolution.
Simulation.Offset Used to scale the output.
The scaling is 65536 for 360° (see object 0x6509).
SSI.
SSI.Direction Sets the measurement direction.
1 = encoder position is reversed
0 = original encoder position
SSI.UnitsPerRevolution Used to scale the output (see object 0x6001). Value range: 1000-65536. Higher values
provide better position resolution.
SSI.Offset Used to scale the output.
The scaling is 65536 for 360° (see object 0x6509).
SSI.GrayCode 0 = binary code is used
1 = Gray code is used
SSI.Databits Number of data bits being read from the SSI encoder.
SSI.Positionbits Number of position bits within the data bits.
SSICRC.
SSICRC.Direction Sets the measurement direction.
1 = encoder position is reversed
0 = original encoder position
SSICRC.UnitsPerRevolution Used to scale the output (see object 0x6001).
Value range: 1000-65536.
Higher values provide better position resolution.
SSICRC.Offset Used to scale the output.
The scaling is 65536 for 360° (see object 0x6509).
SSICRC.CRCPoly CRC generator polynomial used to verify the data.
QEP.
QEP.Direction Sets the measurement direction.
1 = encoder position is reversed
0 = original encoder position
QEP.PulsesPerRevolution QEP encoder parameter of pulses/revolution.
For QEP encoders, the DS 406 object 0x6001.
Measuring units per revolution is always set to 4 times of pulses/revolution of the
encoder.
QEP.Offset Used to scale the output.
The scaling is 65536 for 360° (see object 0x6509).
BiSS.
BiSS.Direction Sets the measurement direction.
1 = encoder position is reversed
0 = original encoder position
BiSS.UnitsPerRevolution Used to scale the output (see object 0x6001).
Value range: 1000-65536.
Higher values provide better position resolution.
BiSS.Offset Used to scale the output.
The scaling is 65536 for 360° (see object 0x6509).
BiSS.DataLengthMT Number of bits of multi-turn part of the encoder.
For single-turn BiSS encoders this parameter must be set to 0.
BiSS.DataLengthST Number of bits of single-turn part of the encoder.
BiSS.DataLengthMF Number of bits for manufacturer-specific data field of a BiSS encoder, e.g. Hengstler
BiSS encoder AC58/0022 has 2 alignment bits plus 1 error bit and 1 warning bit.
BiSS.Frequency Clock frequency for the BiSS encoder in MHz.
It supports 4 possible frequencies: 8, 4, 2 or 1 MHz
