Abstract

PURPOSE:To give a switching control to the testing speed of a main body tester by switching automatically the resistance value of a variable resistor with a microcomputer, to ensure a simple attachment of the tester to an existing equipment and at the same time to give no evil effect to a main body speed controller. CONSTITUTION:A means is provided to switch automatically the resistance value of a variable resistor with a microcomputer. For instance, an input data is supplied to a logical circuit IC11 from an information signal generating source via data buses DB0-DB3. Then an instruction showing the coincidence of board addresses is fed to the IC11 via an AND gate 13, and input signals are supplied to input terminals A-D of a safety circuit IC12. At the same time, the corresponding output signals are transmitted through output terminals 1-8 as ON signals. This ON signal is transmitted to each relay coil via a photocoupler, and then the variable resistor is actuated via the corresponding relay circuit. Then the resistance value corresponding to each ON signal is set to control the speed of a tester.

Many speed changes are possible.

FIG. 7 shows examples of speed changes corresponding to each channel of the speed control TLL device of the present invention. The speed change range due to wood Vi purchase is equal to the capability range of the original equipment, and the speed at which each speed changes is 1/? It is the same as the V frequency circuit, and even if you change the resistance (Po), the motor's rotation speed will not actually follow.

As explained above, the speed of this device can be precisely controlled by the micro convenience store L-Y. However, as mentioned above, when the number of switching steps increases, the motor rotates only 3 times! ! It becomes common to change the degree to 10, 20, or 40 revolutions per second - J degrees.

In Fig. ε), the solid line shows the actual speed change when the speed is made smaller. The deceleration and acceleration of the motor are constant (' (15), but it is shown that the true slope (dotted line) can be approximated by changing the resistance value in detail.
