12.4.9 Machining Parameter Tuning

12.4.9.1 Machining parameter tuning (AI contour)

In advanced preview control, AI advanced preview control, and AI contour control, by setting a

velocity-emphasized parameter set and precision-emphasized parameter set and setting the precision level

matching a machining condition such as rough machining or finish machining on the precision level

setting screen or by programming, the parameters suitable for the condition can be automatically

calculated to perform machining.

On this screen, the parameter sets for emphasis on velocity (precision level 1) and emphasis on precision

(precision level 10) can be set.

Set the following parameters:

• Acceleration rate of acceleration/deceleration before interpolation

• Acceleration change time (bell-shaped)

• Allowable acceleration change value for each axis in velocity control based on acceleration change

under jerk control

• Allowable acceleration change value for each axis in acceleration change under jerk control in

successive linear interpolation operations

• Ratio of the change time of the rate of change of acceleration in smooth bell-shaped

acceleration/deceleration before interpolation

• Allowable acceleration rate

• Acceleration rate of acceleration/deceleration after interpolation

• Corner speed difference

• Maximum feedrate

• Items that can be set freely (2 items)

For details of each parameter, see the descriptions of AI contour control.

By setting bit 0 (MPR) of parameter No. 13601 to 1, this screen can be hidden.

12.4.10.7 Displaying and setting the servo gain tuning screen

On the servo gain tuning screen, it is possible to adjust the following parameters automatically so that

optimum velocity gain can be set easily according to the machine characteristics.

• Load inertia ratio (parameter No. 2021)

• Velocity gain multiplier during cutting (parameter No. 2107)

• Velocity gain multiplier during high speed HRV current control (parameter No. 2335)

Displaying and setting the servo gain tuning screen

The servo gain tuning screen can be displayed from the parameter setting support screen. For the

display procedure, see "Parameter setting support screen (axis setting)" described earlier.

There are two types of screen display for the servo gain tuning screen.

On the automatic tuning screen, servo software calculates the optimum servo loop gain of all axes or a

selected axis and automatically sets VELOCITY GAIN, CUT OVR, and H. SP HRV.

On the manual tuning screen, VELOCITY GAIN, CUT OVR, and H. SP HRV of the desired axis can be

set directly with MDI keys.

VEL. GAIN TUN. STATUS

The automatic tuning status is displayed. The automatic tuning status is indicated by one of the

following four states: "tuning finished", which indicates that automatic tuning is completed, "tuning not

finished", which indicates that automatic tuning is not completed, "tuning in progress", which indicates

that automatic tuning is in progress, and "initial status error", which indicates that automatic tuning is not

completed successfully.

For the axis for which automatic tuning is completed, TUN. FINISH is displayed under VEL. GAIN TUN.

STATUS. For the axis for which automatic tuning is in progress, ON TUNING is displayed. For the

axis for which automatic tuning is not completed successfully, INIT. ERR is displayed. For the axis for

which automatic tuning is not completed, no message is displayed under VEL. GAIN TUN. STATUS.

Even when automatic tuning of an axis is completed, however, if automatic tuning is performed again, the

previous message is cleared. Therefore, if automatic tuning is interrupted, the indication becomes blank.

CNC mode when the velocity gain is set

When setting the velocity gain on the servo gain tuning screen, set PARAMETER WRITE to 1 (enabled)

on the setting screen and set the CNC in the MDI mode.

If the velocity gain is set when PARAMETER WRITE is 0, a warning saying "WRITE PROTECT" is

issued. If the velocity gain is set in other than the MDI mode, a warning saying "WRONG MODE" is

issued.

Servo gain automatic tuning screen

On the automatic tuning screen, servo software calculates the optimum servo loop gain of all axes or a

selected axis and automatically sets VELOCITY GAIN, CUT OVR, and H. SP HRV. This process is

called automatic tuning.

When soft key [ALL AX] is pressed on the automatic tuning screen, the servo loop gain of all axes is

automatically set. When [SEL AX] is pressed, the servo loop gain of the axis selected by the cursor is

automatically set. These processes are called all axis tuning and selected axis tuning, respectively.

OPERATION 12.SETTING AND DISPLAYING DATA

- All axis tuning

When [ALL AX] is pressed on the automatic tuning screen, the following soft keys are displayed and

SERVO GAIN TUNING (AUTO-TUN. ALL AXES) is indicated on the title bar of the screen.

Fig. 12.4.10.7 (d) Automatic tuning screen (all axis tuning) (10.4-inch)

- All axis batch tuning

When no axis in a path is being subjected to automatic tuning, soft key [ALL AX TUNING] ([EXEC

ALL] for the 8.4-inch display unit) is displayed.

When soft key [ALL AX TUNING] is pressed during all axis tuning, all axes are subjected to automatic

tuning one by one, beginning with the first axis. However, the targets of automatic tuning are only the

axes for which automatic tuning is not completed. For example, in the conditions shown in the above

figure, automatic tuning starts with the X-axis and, when the X-axis is completed, proceeds to the Z-axis.

The Y-axis and C-axis are not subjected to automatic tuning.

The cursor keys are disabled during all axis batch tuning. Upon completion of automatic tuning of all

axes, the cursor returns to the first axis and the cursor keys are enabled.

If the screen is switched to another during all axis batch tuning, automatic tuning is canceled when

automatic tuning of the current axis is completed. To start automatic tuning again, display this screen

and press soft key [ALL AX TUNING].

NOTE

1 The axis for which TUN. FINISH or INIT. ERR is indicated under VEL. GAIN

TUN. STATUS is not subjected to automatic tuning.

2 If the screen is switched to another during all axis batch tuning, all axis batch

tuning is aborted.

- All axis step tuning

When no axis in a path is being subjected to automatic tuning, soft key [ONE AX TUNING] ([ONE EX]

for the 8.4-inch display unit) is displayed.

When soft key [ONE AX TUNING] is pressed, as in all axis batch tuning, the axes for which automatic

tuning is not completed are subjected to automatic tuning one by one, beginning with the first axis.

Each time an axis is subjected to automatic tuning, however, automatic tuning stops. At this time, the

cursor automatically moves to the next axis for which automatic tuning is not completed.
