F262¹ÊÕϺ¬Ò壺External Short at Status Outputs״̬Êä³ö´¦µÄÍⲿ¶Ì·
Description:¹ÊÕÏ˵Ã÷£º
Status outputs are monitored for short circuits and thermal overload.

• If output current exceeds 350mA for about 1¦Ìs, then this is acknowledged as a short circuit and the pertinent channel is shut off.Èç¹ûÊä³öµçÁ÷³¬¹ý350mA³ÖÐøÔ¼1¦Ìs£¬ÔòÕâ±»ÈÏΪÊǶÌ·£¬Ïà¹ØͨµÀ±»¹Ø±Õ¡£
The output remains off unti the error is cleared.

• With thermal overload, the error is set and the output(s) shut off. After the driver has cooled off, the outputs are switched back on and so on.

The error, however, remains until it is cleared. Thermal overload can occur if several outputs are overloaded in excess of 80 mA.µ«ÊÇ£¬´íÎó½«Ò»Ö±´æÔÚ£¬Ö±µ½Çå³ýΪֹ¡£Èç¹û¶à¸öÊä³ö¹ýÔس¬¹ý80 mA£¬¿ÉÄܻᷢÉúÈȹýÔØ¡£

Cause:ÔÒò£º
1. Short circuited outputs (X2/6, X2/7, X2/8, X2/9, X2/10, X2/20, X2/21, X2/22)

1. Eliminate short circuit or limit switching current (< 350 mA)
