EXAMPLE MANUAL 49
Part 4: "Shows the consumption of motors"
The speed drives have an analog output (0 to 10V) proportional to the current consumed by the motor.
In this example, the following connections have been made:
- The X axis drive’s current output is connected to the analog input 1 of the CNC.
- The Z axis drive’s current output is connected to the analog input 2 of the CNC.
- The spindle (S) drive’s current output is connected to the analog input 3 of the CNC.
Therefore, variables "ANAI1”, “ANAI2” and “ANAI3” show the analog voltage corresponding to the currents of the
X and Z axes and of the spindle S.
21 symbols (0-20) are used to display the value of the current, in increments corresponding to 0.5V.
To select the right symbol each time, the formula: "ABS ROUND (ANAI1/0.5)" is applied. In other words, the
rounded-up absolute value of the result of the operation "ANAI1/0.5".
