EnDat Encoders (Type 11)
Bits Description
0-4 Number of bits of single turn data available from encoder.
8-12 Number of bits of multi-turn data available from encoder.
16 Set if analog inputs are supplied by encoder.
17 If set, use multi-mode port.
18
If set, read position using EnDat 2.2 style commands rather than the default 2.1 style.
20-23
Number of least significant bits of the encoder reading to discard.
Absolute A Encoders (Type 14)
Bits Description
0-5 Number of bits of single turn data.
8-12 Number of bits of multi-turn data.
16-19 Number of LSB to discard from reading.
20-22 Number of consecutive CRC errors to ignore before generating an error.
24-27 Encoder sub-type (0=Tamagawa, 1=Panasonic absolute, 2=HD systems, 3=Panasonic
Incremental, 4=Sanyo Denki).
28 Bit rate (set for 4 Mbit, clear for 2.5 Mbit).
30 If set, treat encoder battery errors as warnings.
Incremental A Encoders (Type 14)
Bits Description
0-5 Number of bits of single turn data.
8-12 Number of bits of multi-turn data.
16-19 Number of LSB to discard from reading.
20-22
Number of consecutive CRC errors to ignore before generating an error.
24-27
Encoder sub-type (0=Tamagawa, 1=Panasonic absolute, 2=HD systems, 3=Panasonic
Incremental, 4=Sanyo Denki).
28 Bit rate (set for 4 Mbit, clear for 2.5 Mbit).
30 If set, treat encoder battery errors as warnings.
BiSS Encoders (Type 13)
Bits Description
0-5 Number of bits of single turn data.
8-12 Number of bits of multi-turn data.
15
If set, assume the encoder position data wraps after the number of encoder counts
programmed in parameter 0x62.
16 Set for mode-C encoder format.
20 Set if encoder error and warning bits are active low.
21
Set if encoder status bits are sent before position data, clear if status bits are sent after
position data.
22 Set if encoder error bit is transmitted before warning bit. Clear for warning bit sent first.
24-26
Number of alignment bits (reserved bits sent before position info).
28
Use multi-mode port if set. If clear use primary encoder interface.
30 Set for 2.5MHz baud rate, clear for 4MHz baud rate.
