• When the appropriate movement range cannot be obtained
• When the load inertia ratio changes greatly
• When the rigidity of the mechanical system is too low
• When the system uses P/PI switching mode
• When the system uses two stages of gain switching
• When the system uses position loop feed forward
Confirmations before execution of Automatic Gain Adjustment
When executing automatic gain adjustment, please be sure to confirm the following points:
• The main power circuit is ON
• Servo driver is in OFF state
• System control mode is not torque control
• It is not in motor testing mode (JOG function)
• It is not in on-line tuning function
