I have a robot that uses 4 mechanical arms. Each mechanical arm have 4 "READYTOSKY 30kg" servo motors on them. There is a moment that I need to use the absolute maximum force of only two mechanical arms (while the other two will stay still). Even though I do not change the coordinates of the other two mechanical arms (which I am not using) they consume voltage and "takes away" the full potential of force from the other two.
Is there a way to stop the voltage consumed by the two other arms just for a brief moment using the Arduino code? shortly afterwards they will get back the voltage they need.

    if(level==25)                                                     
      { 
        pwm.setPWM(12, 0, 200);
        pwm.setPWM(13, 0, 255);
        pwm.setPWM(14, 0, 430);
        delay(100);
        pwm.setPWM(1, 0, 380);                                      
        pwm.setPWM(2, 0, 520);
        delay(500);
        pwm.setPWM(0, 0, 170);
        delay(600);



        stepperten.setCurrentPosition(0);                            
        while (stepperten.currentPosition() != (-3*200)) 
        {
        stepperten.setSpeed(-600); 
        stepperten.runSpeed();
        }

        steppertwist.setCurrentPosition(0);                        
        while (steppertwist.currentPosition() != (100)) 
        {
          steppertwist.setSpeed(200);
          steppertwist.run();
        }

        stepper1.setCurrentPosition(0);
        while(stepper1.currentPosition() != (30))         
        {
          stepper1.setSpeed(200);
          stepper1.run();
        }

        // stepperten.setCurrentPosition(0);                         
        // while (stepperten.currentPosition() != (-3*100)) 
        // {
        // stepperten.setSpeed(-600); 
        // stepperten.runSpeed();
        // }

        pwm.setPWM(1, 0, 295);   //THIS IS THE MOEMENT I NEED TO STOP VOLATE FOR OTHER ARMS                               
        pwm.setPWM(2, 0, 400);   //AND GET THE MAXIMUM VOLTAGE POSSIBLE ON THESE TWO ARMS
        delay(1500);                                  
        pwm.setPWM(12, 0, 125);
        // pwm.setPWM(14, 0, 395);

        array1[25][0] = 170;                           
        array1[25][1] = 295;
        array1[25][2] = 400;
        array1[25][3] = 153;
        array4[25][0] = 125;
        array4[25][1] = 255;
        array4[25][2] = 395;
      }
