malfunction caused by EMC noise.
7.3.3 Data setting
Data setting related to position control
Setting item
Feed-forward gain
(Note 1)
Position loop gain (Note 2)
Electronic gear position
selection (Note 3)
Numerator of the electronic
gear ratio (Note 3)
Denominator of the electronic
gear ratio (Note 3)
Completion range setting
Completion delay time
(Note 1) :We promote the adjustment from P022=2.00 at the time of the feed forward
gain adjustment .To make the position deviation of the main and sub motor
small, then increase feed forward gain. When the motor is unstable, then
decrease feed forward gain
(Note 2) :We promote the adjustment from P023=2.00 at the time of the position loop
gain adjustment. To get good accuracy of the position control then increase
posotion loop gain, then to get much power to maintain the positioning then
increase posotion loop gain. Motor is unstable due to too big position loop
gain, then decrease position loop gain.
