Please check the SpinTAC Velocity Move state transition map is shown in Figure 3-8 of the InstaSPIN user guide. Set AccRef to 0 will move from HALT to INIT condition.

how to set AccRef to zero? Because I'm only using SpinTAC Position Move not Velocity Move?

I set STPOSCTL_setAccelerationReference to _IQ(0.0); It doesn't help. any ideas why?

I also need to enable

STPOSCTL_setEnable(stObj->posCtlHandle, true);
STPOSMOVE_setEnable(stObj->posMoveHandle, true);

to make it reset properly, Thanks!
