L6470 abs_pos位长没有文献所说的那么大？

根据文献，abs_pos值是22位2的补码整数。但是当我将位置移动到32768（最大16位2s补码）之上时，该值将重置为负数。即abs_pos值用作16位2s补码值。



此外，使用dSPIN_Move命令并使用dSPIN_BUSY进行检查以确保它已完成移动，忙引脚将提前变高并且移动将无法完成。即我将发送一个dSPIN_Move（''FWD''，4000），它只会移动到目前为止，然后在dSPIN_BUSY变高之前停止而不完成abs_pos的指令移动。还有其他人有这些问题吗？一些指导会有所帮助，除了这些问题，产品运作良好。

以下为原文




From the literature, the abs_pos value is a 22 bit 2's complement integer. but when i move the position above 32768 (16 bit 2s complement maximum), the value resets to negative. I.e. the abs_pos value acts as a 16 bit 2s complement value.



Additionally, using the dSPIN_Move command and using the dSPIN_BUSY to check to make sure it's finished with the move, the busy pin will go high early and the move will not finish. I.e. i will send a dSPIN_Move(''FWD'',4000) and it will only move so far, then stop without completing the commanded move from the abs_pos before the dSPIN_BUSY goes high. Has anyone else has these issues? Some guidance would help, besides these issues, the product works great.


attached is data output from the abs_pos (see line 28774 for example of it ending early) and sample code of how i'm commanding it.
