Location of pins A1 to A49. B1 to B49 are on same order except on the opposite side of board.

IONI card edge connector fits into a standard PCI-Express 8X socket connector.

Pinout

The pinout of IONI drive is provided in the following table.

I/O and low voltage signals
Pin Signal name Pin Signal name
A1 GND B1 5V_IN
A2 RS485_A B2 RS485_B
A3 ADDRSEL1 B3 ADDRSEL2
A4 HSIN1 B4 HSIN2
A5 ANAIN- B5 ANAIN+
A6 GPI1 B6 GPI2
A7 GPI3 B7 GPI4
A8 GPO1 B8 GPO2
A9 GPO3 B9 GPO4
A10 GPO5 B10 GPO6
A11 REGEN_OUT B11 MECH_BRAKE_OUT
A12 ENABLE_IN B12 Reserved/NC
A13 STO2 B13 HALL_W
A14 HALL_V B14 HALL_U
A15 CHA- B15 CHA+
A16 CHB- B16 CHB-
A17 CHC- B17 CHC-
Power signals
Pin Signal name Pin Signal name
A18-A22 GND B18 Not connected
A23 Not connected B19-B22 HV+
A24-A27 PHASE1 B23 Not connected
A28 Not connected B24-B27 PHASE2
A29-A37 PHASE3 B28 Not connected
A38 Not connected B29-B37 PHASE4
A39-A43 PHASE1 B38 Not connected
A44 Not connected B39-B43 PHASE2
A45-A49 GND B44 Not connected
B45-B49 HV+

Note 1: pins marked as Not connected are left empty for to make larger clearance for high voltage signals. Leave these pins unconnected on motherboard designs.

Note 2: Each power signal is present in two pin groups (internally parallel) and these signals should be wired parallel on motherboard.
