8.7 Macro Variables

Macro variables

HNC-818 CNC system provides you with the macro function similar to

high-level language. You may use variables to conduct arithmetic

operation, logical operation, and combined function operations. In

addition, the macro program provides cycle statement, branch statement,

and subprogram calling statements, which makes it easy to create

complex machining programs and avoids complicated calculation that

required in manual programming.

8.8.6 Gantry Synchronization Axis

This function is mainly used for collecting the load currents of two

synchronization axes, as well as the position deviation and the current

deviation of the synchronization axes. See the figure below:

The system automatically generates G codes based on the data

(synchronization axis number, travel, speed) defined in the settings

interface. In the auto mode, run the G code to collect data. In the manual

mode, press the SMPL ST button to manually move the axis to collect

data. After the data collection is completed, the maximum positional

deviation and current deviation values of the synchronization axis will be

displayed in the right pane.

8.8.7 Spindle Acceleration and Deceleration Speed

140

8. Diagnosis

This function is used to test the time that the spindle speed increases

from 0 to the specified speed, and the time that the spindle speed

decreases from the specified speed to 0. See the figure below:

In the auto mode, enter the spindle acceleration and deceleration speed

configuration interface. Set the spindle speed, and the system will

automatically generate simple G-codes, e.g. "M3 S1000 M5 M30". After

running the G code, the system automatically calculates the spindle

acceleration and deceleration speed with specified rotation, and output

the results in the right information pane.

Attention

1.

Make sure the Spindle override adjustment button is in the 100%

position; otherwise, the calculated time may be inaccurate.

2.

Please set the value of the spindle parameter "SPEED ARRIVAL

RANGE" to 0; otherwise, the calculated result may be inaccurate.

8.8.8 Tool Change Time

This function is used to collect tool change signal and calculate the time

required for tool change. See the figure below:

8.8.9 Customized Collection

This function can be uses to capture the value of any register. Users can

customize the conversion coefficient, conversion standard and offset of

the register value. According to the formula "conversion value = original

value * conversion coefficient/conversion standard + offset", users may

convert the register value into real values, such as voltage, current,

position, temperature, and so on. The value collection and configuration

interface is as below:
