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:
Pr17

135.41 Pr16 J

where: J
tot
is total inertia (motor + load) in kgm2
Nm
peak
is available torque with peak current of the system
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 Pr18 using the following formula:

If the resulting calibration is unsatisfactory, repeat the procedure with lower values for
Pr16.
If the risult is <1, Pr18 must be =1.
