Comment
‘0’ = no failure
‘1’ = failure: indicates that the charge pump does
not reach the required voltage level. Note 1
Translator micro-step position
‘1’ = Open coil detected
‘1’ = Open coil detected
‘0’ = no failure
‘1’ = failure: indicates that over current is
detected at bottom transistor XN-terminal
‘0’ = no failure
‘1’ = failure: indicates that over current is
detected at top transistor XN-terminal
‘0’ = no failure
‘1’ = failure: indicates that over current is
detected at bottom transistor XP-terminal
‘0’ = no failure
‘1’ = failure: indicates that over current is
detected at top transistor XP-terminal
‘0’ = no failure
‘1’ = failure: indicates that over current is
detected at bottom transistor YN-terminal
