EVAL6482H的getStatus返回值为0xE403

我用EVAL6482H板驱动步进电机，其规格如下，

工作电压：2.5v
额定电流/相：0.49A
供电电压：20v

我将参数设置如下

Stepper.setParam（TVAL_HOLD，0x02）;
Stepper.setParam（TVAL_RUN，0x02）;

Stepper.setParam（OCD_TH，0x08）;

Stepper.setParam（CONFIG，0xF788）;
Stepper.setParam（GATECFG1,0xC7）;
Stepper.setParam（GATECFG2,0x61）;

Stepper.setParam（T_FAST，0x47）;
Stepper.setParam（TON_MIN，0x07）;
Stepper.setParam（TOFF_MIN，0x1F）;

但是，getStatus的返回值为0xE403（1110 0100 0000 0011），表示欠压锁定且标志LED保持闪烁。


任何人都可以帮我找出问题吗？谢谢。

恩典

I have used EVAL6482H board to drive a stepper motor with a spec as followed,


Operating voltage: 2.5v
Rated current/ phase: 0.49A
Supply voltage: 20v


I set the parameter as followed



   Stepper.setParam(TVAL_HOLD, 0x02);
   Stepper.setParam(TVAL_RUN, 0x02);


   Stepper.setParam(OCD_TH, 0x08);


   Stepper.setParam(CONFIG, 0xF788);
   Stepper.setParam(GATECFG1, 0xC7);
   Stepper.setParam(GATECFG2, 0x61);


   Stepper.setParam(T_FAST, 0x47);
   Stepper.setParam(TON_MIN, 0x07);
   Stepper.setParam(TOFF_MIN, 0x1F);


However, the return value from getStatus is 0xE403 ( 1110 0100 0000 0011), which indicates the undervoltage lockout and the flag LED keep winkling.


Can anyone help me to find out the problem?? Thank you.
