IONI SimpleMotion address selection (ADDRSEL)

IONI drive will generate it's own SimpleMotion address (numeric address value starting from 1 on a multidrop bus) by measuring external resistors connected between ADDRSEL1 and ADDRSEL2 pins vs GND pin. These resistors are placed on motherboards like IONICUBE.

Address generation

Final address of IONI drive is calculated by formula

$ Address = DecadeAddres + SingleDigitAddress + SMO $

In above equation SMO is the SimpleMotion bus address offsetSMO adjustable through Granity and it defaults to 0. Values of SingleDigitAddress and DecadeAddress depend on the resistors connected to ADDRSELx pins.

DecadeAddress

DecadeAddress depends on resistor between pins ADDRSEL2 and GND by following table:

DecadeAddress	ADDRSEL2 resistor in Ohms (1% tolerance)	Notes
0	open circuit
10	5600
20	2700
30	1822	Can be made by connecting 2700 and 5600 ohm in parallel
40	3900
50	7200
Force DFU mode	11200	2x5600 ohm in series

SingleDigitAddress

SingleDigitAddress	ADDRSEL1 resistor in Ohms (1% tolerance)	Notes
1	open circuit
2	5600	5600
3	2700	2700
4	1822	Can be made by connecting 2700 and 5600 ohm in parallel
5	3900
6	7200
7	11200	2x5600 ohm in series
Reserved, don't use	22400	4x5600 ohm in series
