AMM80 • SSI, BiSS, & RS-485
The Preset value must be less than the “Total Hardware resolution”.
NOTE
We suggest setting the preset when the encoder shaft is in stop.
NOTE
Please note that the bit structure of the
Preset
registers is as follows:
Byte 11 Byte 12 Byte 13 Byte 14 Byte 15
7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 23 22 21 20 19 18 17 16 31 30 29 28 27 26 25 24 39 38 37 36 35 34 33 32
0 0 0 0 0 0 0 0 0 0
Always set to 0
lsbit with 23-bit encoder
lsbit with 20-bit encoder lsbit with 17-bit encoder
Byte 16 Byte 17
47 46 45 44 43 42 41 40 55 54 53 52 51 50 49 48
0 0 0 0 0 0 0
Always set to 0
msbit with all encoders
NOTE
Please note that:
•
bytes 11, 12, 13, 14 and bit 32 of byte 15 are used for singleturn
information;
•
bit 32 of byte 15 is the msbit of the singleturn information and is kept
fixed;
•
lsbit of the singleturn information changes according to the resolution
of the encoder, it is:
◦
bit 16 for 17-bit singleturn resolution;
◦
bit 13 for 20-bit singleturn resolution;
◦
bit 10 for 23-bit singleturn resolution;
•
bits 33 to 39 of byte 15 and bytes 16 and 17 are used for multiturn
information;
•
bit 48 of byte 17 is the msbit of the multiturn information and is kept
fixed;
•
bit 33 of byte 15 is the lsbit of the multiturn information and is fixed
because the number of revolutions is always 65,536 (16 bits) in all
models;
•
bits from 49 to 55 in byte 17 are always set to 0;
•
bits 8 and 9 in byte 12 are always set to 0;
•
all bits in byte 11 are always set to 0.
