Notes: Due to motor inductance, the actual current in the

 

coil may be smaller than the dynamic current 

 

settings, particularly under high speed condition.

 

 
 
 
 
 
 

DIP Setting for Standstill Current

 

 

SW5  is  used  for  this  purpose.  OFF  meaning  that  the  standstill  current  is  set  to  be  half  of  the  selected  dynamic  current,  and  ON  meaning  that 
standstill current is set to be the same as the selected dynamic current. The current automatically reduced to 60% of the selected dynamic current 
0.5  second  after  the  last  pulse  when  use  automatic  idle-current  reduction  mode.  Theoretically,  this  will  reduce  motor  heating  to  36%  (due  to 
P=I2*R) of the original value.
