14.29 Real-Time Tuning 1 (Speed Gain)

14.29.3 Description of Operation

 When the function of real-time tuning 1 is validated, the speed control gain is switched according to the estimated inertia
size.
 During the cutting command (during modal), the value of speed control gain is retained. Once the modal command is
removed, the speed control gain switching is resumed.
 If you do not want to validate the speed control gain switching, turn ON the signal "Real-time tuning 1: Speed control gain
hold-down command (VGHLDC:Y18CA)". If you want to resume the speed control gain switching, turn OFF the signal
"Real-time tuning 1: Speed control gain hold-down command (VGHLDC:Y18CA)".

(1) Enable the real-time tuning 1 function.
(2) The speed control gain switching is initiated and the speed control gain is switched according to the estimated inertia
size.
(3) Validate cutting command.
(4) Inertia estimation process is stopped and the estimated inertia value is retained. Along with this, the speed control gain
switching process is stopped and the speed control gain value is retained as well.
(5) The cutting command is finished and the modal is removed.
(6) The inertia estimation and gain switching processes are resumed.
(7) Turn ON the signal "Real-time tuning 1: Speed control gain hold-down command (VGHLDC:Y18CA)".
(8) Inertia estimation process is stopped and the estimated inertia value is retained. Along with this, the speed control gain
switching process is stopped and the speed control gain value is retained as well.
(9) Turn OFF the signal "Real-time tuning 1: Speed control gain hold-down command (VGHLDC:Y18CA)".
(10) The inertia estimation and gain switching processes are resumed.
