5.3 Advanced Autotuning (Fn201)
This section describes the adjustment using advanced autotuning.
• Advanced autotuning starts adjustments based on the set speed loop gain (Pn100).
Therefore, precise adjustments cannot be made if there is vibration when starting
adjustments. In this case, make adjustments after lowering the speed loop gain
(Pn100) until vibration is eliminated.
• Before performing advanced autotuning with the tuning-less function enabled
(Pn170.0 = 1: Factory setting), always set calculate the load moment of inertia. The
tuning-less function will automatically be disabled, and the gain will be set by
advanced autotuning.
With the load moment of inertia is not calculated, "Error" will be displayed on the panel
operator, and advanced autotuning will not be performed.
• If the operating conditions, such as the machine-load or drive system, are changed
after advanced autotuning, then change the following related parameters to disable
any values that were adjusted before performing advanced autotuning once again
with the setting to calculate the moment of inertia. If advanced autotun- ing is
performed without changing the parameters, machine vibration may occur, resulting
in damage to the machine.
Pn00B.0=1 (Displays all parameters.)
Pn140.0=0 (Does not use model following control.)
Pn160.0=0 (Does not use anti-resonance control.)
Pn408=n.00
口
0 (Does not use friction compensation, 1st notch filter, or 2nd notch
filter.)
5.3.1 Advanced Autotuning
Advanced autotuning automatically operates the servo system (in reciprocating movement in the
forward and reverse directions) within set limits and adjust the DRIVER automatically according to
the mechanical characteristics while the servo system is operating.
Advanced autotuning can be performed without connecting the PC or PLC...etc. The following
automatic operation specifications apply.
•
Maximum speed: Rated motor speed × 2/3
•
Acceleration torque: Approximately 100% of rated motor torque
The acceleration torque varies with the influence of the moment of
inertia ratio
(Pn103), machine friction, and external disturbance.
•
Travel distance: The travel distance can be set freely. The distance is factory-set to a
value equivalent to 3 motor rotations.
