Let the equipment system move.
Is the motor quiet?
Saving complete
・Check the motor motion by test operation
or external command input.
・Repeat the system entire motion several times.
If you need to improve the response further, gradually increase
the control gain set within the range where the motor will not make noise
and perform tuning each time.
The following is desired:
・Shorter settling time
・Better responsiveness
・In the parameter saving mode, save the parameters
to EEPROM in the
drive
.
・If you shut down the
drive
without saving the parameters, the
setting changes will not take effect.
・No noise?
Visually check
the motion etc.
Change the inertia ratio.
（This is a sample image: the inertia ratio is 250 .）
