• When the mechanical system can only operate in a single direction
• When the mechanical system's rotating range is less than 3 revolutions
(2) The system cannot be executed correctly
• 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
• No alarm occurred
• If the speed control is used to execute automatic gain adjustment, it will automatically switch to
position control during adjustment, and switch back to speed mode after the adjustment is
