11-1 Outline of Adjustment Functions
The Servo Drive must operate the Servomotor in response to commands without time delay and with
reliability to maximize the performance of the machine. The Servo Drive is adjusted according to the
characteristics of the machine.
Precautions for Safe Use
• Motor operation is required during adjustment. Take sufficient measures to ensure safety.
• Especially, if unusual noise or vibration occurs, immediately turn OFF the power supply or
turn OFF the Servo.
The adjustment function of the Sysmac Studio Automation Software and the automatic adjustment
function of the Servo Drive facilitate adjustment according to your purpose.
Use the Sysmac Studio to execute the following adjustment functions and monitor data for adjustment.
For how to operate the Sysmac Studio, refer to the
Sysmac Studio Drive Functions Operation Manual
(Cat. No. I589).
The Servo Drive has the following automatic adjustment functions.

Adjustment Function of Sysmac Studio
Function
Description
Reference
Easy Tuning
Adjusts the gain automatically while motor operation is repeated.
Use this function to perform adjustment easily.
Advanced Tuning
Uses simulation to perform adjustment with minimum motor opera-
tion. Fine setting adjustment is possible for each parameter includ-
ing the gain and filter.
Manual Tuning
Adjusts multiple gains at a time according to the one set parameter.
Data Trace
Measures commands to the motor and motor operation (velocity,
command torque and following error) and displays them with wave-
forms.
FFT
Measures the frequency characteristics of velocity closed loop.
Damping Control
Automatically detects the vibration frequency. This function makes it
easy to set damping control.
Automatic Adjustment Function of Servo Drive
Function
Description
Reference
Load Characteristic Estima-
tion
Estimates the load characteristics of the machine in realtime and
sets the values of the inertia ratio and friction torque compensation
automatically according to the result of estimation.
Adaptive Notch Filter
Reduces vibration by estimating the resonance frequency and auto-
matically setting the frequency of the notch filter.
