SD710 Series Servo Drive Technical Manual Chapter 6 Adjustment

6.3.2 Smart setting operation procedure
(1) Pre-implementation recognition matters
Be sure to check the following settings before executing the smart setting. If the settings are not set correctly, the
function will not be executed during operation.
⚫
No overtravel has occurred.
⚫
Non-torque control.
⚫
Gain switching selector switch for manual gain switching (Pn110.X = 0) and for gain 1.
⚫
No alarms or warnings have occurred.
⚫
The adjustment-free control function is disabled (Pn175.X = 0).
Precautions
●
When the speed control state performs no-command intelligent setting, it will automatically
switch to position control to perform adjustment. Return to speed control when adjustment is
complete.
●
Intelligent setting with command cannot be executed in the torque control state.
●
The command pulse input multiplier switching function becomes disabled during the
execution of the setting only.
(2) Examples of adjustments that could not be performed or failed
Intelligent settings will not be executed properly in the following cases.
⚫
Motor is in position control during power-on (in servo ON) (when there is commanded intelligent setting)
⚫
When the mechanical system can only operate in one direction
⚫
Narrower range of motion, when under 0.5 turns
⚫
When the rotational inertia varies within the set operating range
⚫
When the dynamic friction of the machinery is high
⚫
When the rigidity of the machine is low and vibration occurs during positioning movements
⚫
When speed feedforward is input
⚫
Smaller positioning completion signal threshold (Pn262)
Precautions
●
If the no command intelligent adjustment of variable inertia load fails, please change the
adjustment mode and use the one-touch adjustment or adjustment-free function.
●
For smart adjustment, set "Electronic gear ratio (Pn204/Pn206)" and "Positioning completion
range (Pn262)", set to the value for the test run, otherwise the adjustment may fail or the
adjustment result may not match the result of the test run.
