In Fig. 4, the circuit of voltage detecting and conversion equipment mainly is made of two integrated voltage comparators.This circuit employing ± 24V dual power supply, the cross-over connection of power filtering capacitor (C1, C2) difference is between two groups of power positive cathodes and 0V end.Voltage comparator (U1A) and peripheral circuit thereof constitute the voltage detecting circuit that F.F./worker advances conversion: the torque that the in-phase input end of voltage comparator (U1A) connects servo-driver (11) monitors output terminal (IM), and torque monitors that output earth terminal (GND) connects power supply 0V end; Resistance (R1), resistance (R3) and potentiometer (R2) are formed bleeder circuit, cross-over connection between the both positive and negative polarity of power supply, the inverting input of the adjusting termination voltage comparator (U1A) of potentiometer (R2).Photoelectrical coupler (U2) and pull-up resistor (R4) are formed signaling conversion circuit: the LED of optocoupler (U2) importation connects, is the forward cross-over connection between power positive cathode with pull-up resistor (R4), and the tie point of the two is connected with the output terminal of voltage comparator (U1A); The useful input signal input end (X0) of the output termination controller (15) of optocoupler (U2), input common port (COM).
Voltage comparator (U1B) and peripheral cell thereof: resistance (R5), resistance (R7), potentiometer (R6) and optocoupler (U3) constitute the worker and advance/voltage detecting and the change-over circuit of rewind down conversion.The voltage detecting circuit that its circuit structure and F.F./worker advance to change is basic identical; Difference only is: the inverting input of voltage comparator (U1B) switches through square and monitors that output terminal (IM), in-phase input end connect potentiometer (R6) adjustable side of bleeder circuit, another useful input signal input end (X1) of the output termination controller (15) of optocoupler (U3) and input common port (COM).
Circuit theory: voltage comparator (U1A) realizes that F.F./worker advances the voltage detecting of conversion, by regulator potentiometer (R2) set the high threshold signal potential, (U1A) inverting input that is added to voltage comparator, the torque of servo-driver monitors the torque monitor voltage of output terminal (IM), being added to voltage comparator (U1A) in-phase input end compares, when the torque monitor voltage is higher than the high threshold signal potential, voltage comparator (U1A) output high level signal.Voltage comparator (U1B) realizes that the worker advances/voltage detecting of rewind down conversion, set the in-phase input end that hangs down the threshold signal current potential, is added to voltage comparator (U1B) by regulator potentiometer (R6), the torque of servo-driver monitors the torque monitor voltage of output terminal (IM), the inverting input that is added to voltage comparator (U1B) compares, when the torque monitor voltage is lower than the threshold signal current potential, voltage comparator (U1B) output high level signal.Photoelectrical coupler (U2, U2) plays conversion and buffer action.The signaling conversion circuit that two optocouplers (U2, U3) are formed is exported two paths of signals respectively to the two switching value input ends (X0, X1) of controller (15) when voltage comparator (U1A, U1B) output high level signal: the useful input signal of switching mode and the worker that F.F./worker advances conversion advance/and the useful input signal of switching mode that rewind down is changed.
Because the actual installation structure of unit head may be different, the resistance that the torque monitor voltage of servo-driver (11) output is subjected in the time of may be with the unit head positive movement increases, and the resistance increase that is subjected in the time of also may be with the unit head positive movement reduces.This routine torque monitor voltage for-3V～+ 3V, the resistance that is subjected to during with the unit head positive movement increase, otherwise can put upside down the polarity of torque monitor voltage when this circuit is imported.Suitably set each divider resistance (ratio of R1～R3, R5～R7), the adjustable extent that makes the high threshold signal potential be 0～+ 3V, the adjustable extent of low threshold signal current potential is-3V～+ 1V.Because of the installation situation difference of every unit head, high and low threshold signal current potential, the real work torque that can export in different process according to servo-driver (11) according to the proportionate relationship of output torque and torque monitor voltage, is determined by debugging.(resistance of R1～R3, R5～R7) can be selected the optional resistance 5.1K Ω of resistance (R4, R8)～24K Ω to resistance between number K Ω～hundreds of K Ω; Two optocouplers (U2, U3) optional TIL117,4N25 etc., optional 100～470 μ F/50V of two electric capacity (C1, C2).
