When P147=1 or 2 the minimum measurable speed can be reduced by a

 

 

 

 

 

 

 

 

factor of 2 or 4 respectively as opposed to 0 or 12 to 20. However, these

 

 

 

 

 

 

 

 

settings increase the actual speed sensing delay. For this reason, P200

 

 

 

 

 

 

 

 

should be parameterized to at least 5ms before the optimization run for the

 

 

 

 

 

 

 

 

speed controller is executed.
