6.4 Intelligent Setting
6.4.1 Summary
Users can choose intelligent setting with command input and no command input:
1)
No command input (When there is no pulse from the controller)
It means the function of automatically adjusting the servo unit according to the mechanical
characteristics when the automatic operation (forward and reverse reciprocating motions) is
performed within the set range. Intelligent settings can be performed without connection to the
control system.
The automatic operation is as follows:
Highest speed: motor rated speed
Acceleration torque: motor rated torque about 100%
Move distance: can be set arbitrarily. The factory setting is equivalent to 3 turns of the
motor
2)
Command input (When a controller sends pulses)
It is the method of automatically adjusting the running command from the host control system.
The command intelligent setting can also be used for additional adjustments after the no-command
intelligent setting. When the correct inertia ratio is set, no-command intelligent setting can be
omitted, and only the intelligent setting operation with Commands is performed.
The intelligent setting process adjusts the following items:
Rotary inertia ratio (No command intelligent setting)
Gain adjustment (speed loop gain, position loop gain, etc.)
Filter adjustment (torque command filter, notch filter)
Friction compensation
IF suppression control (intermediate frequency)
Vibration suppression
Low-frequency vibration suppression (only when Mode = 2 or 3) (No command
intelligent setting)
Cautions
！
The command smart setting starts with the present speed loop gain (Pn101) as a reference. If vibration
occurs at the start of the adjustment, correct adjustment cannot be performed. In this case, pls decrease the
speed loop gain (Pn101) until the vibration disappears, and then readjust.
