Configuration parameters for first BISS encoder.

Name	Index:Sub	Type	Bit Size	Options			Unit	Access	PDO Mapping
Type	0x2201:1	USINT	8	HALL 1 Incremental 2 A-Format 3 BISS 4 REM 16MT 6 SSI 7 iC-MD 8 iC-NQC 9				readonly (default)
The implementation of the BiSS service expects an encoder that has the following frame structure: - SLO line high when ready. - Ack bit (which can be extended to multiple bits by the encoder). - Start bit when the encoder is ready to transmit the data. - CDS bit for register communication. - Payload (composed by Multiturn bits + Singleturn bits + Filling bits, in this order). - Error and warning bits, in this order. - 6-bit CRC. - Timeout.

Function	0x2201:2	USINT	8	Disabled 0 Commutation & Motion Control Feedback 1 Commutation & Monitoring (#0x230A, #0x230B) 2 Motion Control Feedback only 3 Monitoring only (#0x230A, #0x230B) 4 Commutation only 5 Position 6 Commutation & Velocity 7				readwrite
Determines encoder function/purpose. The encoder can be configured for commutation, motion control feedback, monitoring. In monitoring mode, the position and velocity information will be displayed in objects #0x230A & #0x230B. There is an option to configure two motion sensors, one sensor as a motion position sensor, while the other sensor should have commutation and velocity function.

Resolution	0x2201:3	UDINT	32	1		1	Inc/Revolution	readwrite
Number of pulses in one revolution. Most of the BiSS encoders have a binary resolution, which means: Resolution = 2^(number of singleturn bits).

Zero velocity threshold	0x2201:4	UDINT	32	0	1000000	5000	μs	readwrite
Time threshold to set the velocity to 0 if no new position was received from the encoder.

Polarity	0x2201:5	USINT	8	Normal Polarity 0 Inverted Polarity 1				readwrite
If you have an axis with two encoders (one for commutation and one for position and velocity), the direction of each encoder must match for control stability. This polarity parameter can be used for flipping the direction of the position or velocity encoder relative to the sensor used for commutation.

Multiturn resolution	0x2201:6	UDINT	32			0		readwrite
Multiturn resolution in bits. Corresponds to the total number of revolutions that are counted by the encoder.

Clock frequency	0x2201:7	UDINT	32	99	6000	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	0x2201:8	UDINT	32			36	μs	readwrite
Timeout at the end of each BiSS frame, it's part of the BiSS C standard. Refer to your encoder datasheet to check what are the minimum and maximum values for this parameter.

CRC polynom	0x2201:9	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.

Number of filling bits	0x2201:12	USINT	8			0		readwrite
The filling bits are bits that need to be clocked after the singleturn bits and before the error bit, but that are only used as part of the data for CRC calculation. Most BiSS encoders don't have filling bits.

Number of bits to read while busy	0x2201:13	USINT	8			30		readwrite
This value defines the maximum number of bits that should be clocked in order to receive the start bit once the Ack bit was already received. If the Start bit is not received after this time, the error BisSrtBt is raised. If the Start bit is received before this number, the comunication continues normally. It is advised to try to increase this number in case the error BisSrtBt appears, which is likely to happen because the encoder needed more time to process the data before sending the Start bit.

Status bits active value	0x2201:14	BOOL	1	Active low 0 Active high 1				readwrite
Value of the status bits when active. The BiSS-C standard recommends that these bits are active low, so most encoders should work with the default value.
