SYNAPTICON SOMANET Node Series User Manual

Multiturn resolution in bits.
Corresponds to the total number of revolutions that are counted by the encoder.

frequency
0x2202:7 UDINT 32 1000 5000 1000 kHz readwrite
Frequency for the BiSS clock line (MA).
Refer to your encoder datasheet to check what are the minimum and maximum values for this parameter.
The drive can only clock at some discrete frequencies. If the user enters a frequency that is not within these
discrete frequencies, it will be set to the next possible lower frequency.
To calculate what's the real frequency that will be used, you can round up the result of 25000 / Clock
frequency. Then divide 25000 by the rounded value obtained before.
For example, when setting 4000 KHz the real frequency will be 3571.43 kHz.

Timeout 0x2202:8 UDINT 32 36 μs readwrite
Timeout at the end of each BiSS frame, as defined in the BiSS-C standard.
Refer to your encoder datasheet to check what are the minimum and maximum values for this parameter.
To ensure that the BiSS encoder can properly detect it, it's better to set this value a little over the minimum
timeout specified in the datasheet. This is specially important when doing BiSS register communication (OS
command 0), because the CDM bit used in that communication depends on the timeout being detected
consistently by the encoder.

CRC
polynom
0x2202:9 USINT 8 48 readwrite
Polynom for the CRC calculation.
This value is obtained by representing the polynom in reverse order and with the higher exponent omitted.
For example: x^0 + x^1 + x^3 + x^6 is 0b110100, which is equal to 52 in decimal.
The default value of 48 (x^0 + x^1 + x^6) is the one used for most of the BiSS encoders.
