i got it to work!!!
i used this
DRIVE+24 --> TB4 pin 5 ENA+
DI1 --> TB4 pin 6 ENA-
DRIVE+24 --> TB4 pin 7 DIR+
DI2 --> TB4 pin 8 DIR-

but instead of 24v i connected it to ground.
but it only works in one direction and max rpm is 10000 in linuxcnc

edit: sorted max rpm by manuall editing the ini file.

+10V --> TB4 pin 3 SPIN+
AIN --> TB4 pin 2 SPINOUT
GND --> TB4 pin 1 SPIN-
DI1 --> TB4 pin 5 ENA+
GND --> TB4 pin 6 ENA-
DI2 --> TB4 pin 7 DIR+
GND --> TB4 pin 8 DIR-

Note that you would need to program your drive for RUN/DIR mode instead of
FWD/REV mode


Just to confirm , TB4 pins 5,6,7,8 pin to signal polarity are in typo? Should be
DI1 --> TB4 pin 6 ENA+
GND --> TB4 pin 5 ENA-
DI2 --> TB4 pin 8 DIR+
GND --> TB4 pin 7 DIR-
