Adjustment Functions
4. Selecting Machine Rigidity
The machine rigidity number sets the machine rigidity, and can be set to a value from 0 to F hex.
The greater the machine rigidity, the higher the machine rigidity number is. The higher the machine
rigidity is set, the higher the gain can be set.
Under normal conditions, set the machine rigidity gradually from a low level in autotuning. Set the
value in a range where an unusual noise, oscillation, and vibration do not occur.
5. Moving to Autotuning Mode
After setting the machine rigidity, press the Data key to move to Autotuning Mode. (For details,
refer to Autotuning Mode on page 6-16.)
6. Turning ON the Servo
Turn ON the RUN Command Input (RUN). The Servo will turn ON.
7. Executing Autotuning
Press and hold the Increment key until is displayed. (For details, refer to Autotuning
Mode on page 6-16.)
The Servomotor will rotate and autotuning will begin. The operating pattern depends on the
Autotuning Operation Setting (Pn25). If Pn25 is set to 0, the Servomotor will rotate two times in
