4.6. Tuning the Control Loops
The mathematical coefficients of the control loop, an advanced
control algorithm, must be tuned in order to ensure good system
behavior.
These coefficients can be tuned either manually or automatically
(Auto-tuning). Two Auto-tuning procedures are available: one that
calculates the coefficients based only on the user specified motor
inertia ratio (Fast Tuning), and one that sets the coefficients
experimentally by moving the motor and analyzing its behavior
(Fine Tuning).
4.6.1. Manual Tuning
Manual tuning can be performed according to the instructions
provided in the FSP Amplifier User’s Manual.
4.6.2. Auto-tuning
Auto-tuning is applicable in programming mode only
(Pn000.1 = D).
When you select the auto-tuning option from the Maintenance
menu, the Auto-tuning window (Figure 21) is displayed:
