7.16 Intelligent adjustment without command input (Fn201)
The command input type intelligent adjustment function is a function that automatically adjusts the servo drive according
to the mechanical characteristics when automatic operation (forward and reverse reciprocating motion) is executed within
the set range. The Drive can perform intelligent adjustment without connecting to the upper unit.
The specifications for the smart adjustment operation are as follows.
● Maximum speed: Motor rated speed ×
2
3
● Acceleration torque: Motor rated torque (approx. 100%, acceleration torque may fluctuate depending on
rotational
inertia ratio, mechanical friction, external disturbances, etc.).
● Travel distance: Ca
n be set arbitrarily. The factory setting is equivalent to 3 revolutions of the motor
When the Smart Adjustment function is on, the following items will be adjusted.
●
Rotational inertia ratio
●
Gain adjustment (speed loop gain, position loop gain, etc.)
●
Filter adjustment (torque command filter, notch filter)
●
Friction compensation
●
A-type vibration suppression control
●
Vibration suppression
(1) Pre-implementation recognition matters
Be sure to check the settings before performing intelligent adjustment. If the settings are not correct, "NO-OP" will be
displayed and the function cannot be performed.
● The parameter
prohibition function (Fn010) is not set to "Writing prohibition"
● Main circuit power ON
● No overtravel occurred
● Servo is OFF
●
Non-torque control
●
Gain switching switch is manual gain switching
● Gain 1 was selected
●
No alarms or warnings occur
● Hard
-wired base blocking function (HWBB) is disabled
●
Set "presumed inertia" in the state where the no-adjustment function is active, or set the no-adjustment function to be
disabled
(2) Examples of adjustments that cannot be performed
In the following cases, the intelligent adjustment will not be executed properly, so please adjust it by the command input
type advanced auto-tuning adjustment or one-touch tuner.
● When the mechanical system can only operate in one direction
● Narrower range of motion, when under 0.5 turns
(3) Examples of adjustments that cannot be made smoothly
In the following cases, if the intelligent adjustment cannot be made smoothly, please adjust the machine by the command
