9. SPECIAL ADJUSTMENT FUNCTIONS

(1)Parameters No. 7, 34 to 38

These parameters are the same as in ordinary manual adjustment. Gain changing allows the values of ratio of load inertia moment to servo motor inertia moment, position control gain 2, speed control gain 2 and speed integral compensation to be changed.

(2)Ratio of load inertia moment to servo motor inertia moment 2 (GD2B: parameter No. 64)

Set the ratio of load inertia moment to servo motor inertia moment after changing. If the load inertia moment ratio does not change, set it to the same value as ratio of load inertia moment to servo motor inertia moment (parameter No. 34).

(3)Position control gain 2 changing ratio (parameter No. 65), speed control gain 2 changing ratio (parameter No. 66), speed integral compensation changing ratio (parameter No. 67)

Set the values of after-changing position control gain 2, speed control gain 2 and speed integral compensation in ratio (%). 100% setting means no gain change.

For example, at the setting of position control gain 2 100, speed control gain 2 2000, speed integral compensation 20 and position control gain 2 changing ratio 180%, speed control gain 2 changing ratio 150% and speed integral compensation changing ratio 80%, the after-changing values are as follows:

Position control gain 2 Position control gain 2 Position control gain 2 changing ratio /100180rad/s Speed control gain 2 Speed control gain 2 Speed control gain 2 changing ratio /100 3000rad/s Speed integral compensation Speed integral compensation Speed integral compensation changing ratio /100 16ms

(4)Gain changing selection (parameter No. 68)

Used to set the gain changing condition. Choose the changing condition in the first digit. If you set "1" here, you can use the gain changing (CDP) external input signal for gain changing. The gain changing signal (CDP) can be assigned to the pins using the servo configuration software.

Parameter No. 68

0 0 0

Gain changing selection

Gains are changed in accordance with the settings of parameters No. 61 to 64 under any of the following conditions:

0:Invalid

1:Gain changing (CDP) input is ON

2:Command frequency is equal to higher than parameter No. 69 setting

3:Droop pulse value is equal to higher than parameter No. 69 setting

4:Servo motor speed is equal to higher than parameter No. 69 setting

(5)Gain changing condition (parameter No. 69)

When you selected "command frequency", "droop pulses" or "servo motor speed" in gain changing selection (parameter No.69), set the gain changing level.

The setting unit is as follows:

Gain changing condition

Servo motor speed

r/min

(6)Gain changing time constant (parameter No. 70)

You can set the primary delay filter to each gain at gain changing. This parameter is used to suppress shock given to the machine if the gain difference is large at gain changing, for example.
