CALIBRATION WITHOUT INSTRUMENTS 
 

If an oscilloscope is not available, proceed as follows: 
 
A)  Calculate the value of Pr16 as described earlier. 
B)  Calculate Pr17 using the following formula: 
 

Pr

C) Start the drive and, moving the axis with an external control change Pr17 to seek the value 

at which the axis moves as required. 

D) Calculate the value of Pr18 using the following formula:

If the result is less than 1, set Pr18 to 1. 

 
If the resulting calibration is unsatisfactory, repeat the procedure with lower values for Pr16.
