13. Run the drive with a steady Line Speed Reference that results in a motor speed of just
over 2 RPM.
14. Adjust Friction Loss (JLossComp - In11) until the speed PI output is near zero.
15. Run the drive with a steady Line Speed Reference that results in a motor speed near
75% of full speed.
16. Adjust Windage Loss (JLossComp - In12) until the speed PI output is near zero.
17. After threading the machine, if tension deviates during accleration/deceleration, adjust
Inertia Compensation Gain Quadrant 1 and 2 (JLossComp – In9) and Inertia
Compensation Gain Quadrant 3 and 4 (JLossComp – In10) as necessary to reduce
tension deviations.
