7.3.3 Data setting
Data setting related to position control
Setting item | Function code | Setting range, setting contents | ||
P022 | 0.00∼99.99 / 100.0∼655.3 | |||
(Note 1) | ||||
|
| |||
Position loop gain (Note 2) | P023 | 0.00∼9.99 / 100.0 (rad/s) | ||
Electronic gear position | P019 | 00: to the feed back side (FB) | ||
selection | (Note 3) | 01: to the position command side (REF) | ||
| ||||
Numerator of the electronic | P020 | 1∼9999 | ||
gear ratio | (Note 3) | |||
|
| |||
Denominator of the electronic | P021 | 1∼9999 | ||
gear ratio (Note 3) | ||||
|
| |||
Completion range setting | P017 | 0∼9999. / 1000 (10,000) (pulse) | ||
Completion delay time | P018 | 0.00∼9.99 (s) | ||
(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.
