Servo motor & # 8203; Servo motor can make the control speed, position accuracy is very accurate, can convert voltage signal into torque and rotational speed to drive the control target. Servo motor rotor speed by the input signal control, and can be rapid response, in the automatic control system, is used as the performance of the components, and has a small electromechanical time constant, high linearity, initiating character such as voltage, can convert the received electrical signal to the motor shaft angular displacement or angular velocity on output. Servo motor debugging method and matters needing attention to (1) the debugging of the servo motor to 1, the initialization parameters before wiring, initialization parameters first. On the manipulation of the card: choose the right control method; Will reset the PID parameters; Let the electricity control card when the default enabled signal closed; To save the situation, to guarantee the manipulation of the card when power on again for this situation. On the servo motor: setting control method; Set to external control; The encoder signal output of the gear ratio; Set up the relationship with the motor speed of the control signal. In general, argues that the biggest planning to make the servo speed control voltage for the 9 v. 2, connection to control power, cohesion between control card and servo signal lines. The following line is to be answered: control card analog output line, enabling signal lines, servo signal output of the encoder. Review connection without fault, the servo motor and control card,And PC)Access to electricity. This moment motor should not move, and can be used easily rolling force, if not, view can make the signal Settings and wiring. With the rolling force motor, check whether the manipulation of the card correctly detect the change of the motor bearing, or check the encoder signal connection and Settings. 3, test the direction of a closed-loop control system, if the direction of the response signal is not correct, must be disastrous consequences. After open the servo control card enabling signal. This is servo should roll at a low speed, this is the legendary & otherZero drift & throughout; 。 General control card will have zero drift instruction or parameters. Use this command or parameter, the motor speed and direction whether can pass the instructions (Parameters)Manipulation. If can't control, check the analog wiring and control method of parameter Settings. Forward admitted given positive number, motor, encoder count add; Around the given negative, motor, encoder count decreased. If the motor with load, limited range, do not choose this method. Don't give too much test voltage, below 1 v. If direction is not common, can correct control parameters on the card or motor, make it together. 4, inhibition of zero drift in the process of the closed loop control, the existence of zero drift will influence on control effect is must, best to suppress it. Using the control card or suppress zero drift on the servo parameters, careful adjustment, make the speed of the motor is close to zero. As zero drift itself also has necessarily randomness, so, don't require motor speed must be zero. 5, to set up the closed loop control again after add servo control card can spread signal, on the manipulation of the card to enter a smaller share of the gain, as to how much smaller, this only by feeling, if not trust, real input control card can allow the minimum value. Turn control card and servo enable signal. At this time, the motor should now can make action in accordance with the movement instruction is roughly. 6, adjusting closed-loop parameters fine tuning control, ensure the motor according to the instruction motion control card, this is must do homework, and this part of the work, more experience, here only escapes. 1 (2) pay attention to matters of servo motor, servo electric motor oil and water to maintain A: servo motor can be used in water or oil droplets into the place, but it is not completely waterproof or oil. Therefore, servo motor should not be placed or used in the water or oil contamination of environment. B: if the servo motor to connect to a reduction gear, using the servo motor should be oil seal, in order to avoid the reduction gear oil into the servo motor. C: servo motor cable don't immersed in oil or water. 2, servo motor cable & rarr; Relieve stress A: ensure that the cable is not because of external bending force or by its weight or straight load torque, especially in the cable or cohesion at the exit. B: in the case of a servo motor to move, should put the cable (Is the root that along with the electrical equipment)Firmly fixed to a stop (Relative motor)And should be with an additional cable installed in the cable support to extend it, so that the bending stress can reduce to a minimum. C: do the bend radius of the cable may be big. 3, A: servo motor allows the shaft end of the load and the device running when added to the radial and axial load on the shaft servo motor control in within the specified value of each type. B: be very careful when a rigid coupling the device, in particular, excessive bending load may cause the damage of the shaft end and bearing or wear. C: it is best to the flexible coupling, so that the radial load is lower than the allowable values, it is designed for high mechanical strength of the servo motor planning. D: to allow the axle load, please refer to the & otherAllow the axial load of table & throughout; (Using the manual)。 Pay attention to A 4, servo motor device: the device/disassemble coupling parts to the end of the servo motor, don't use hammer directly and shaft end. (Hammer directly and shaft end, at the other end of the servo motor shaft encoder to knocked bad)B: try to align the shaft end to the best conditions (Good to owe may cause oscillation or bearing damage)。 Can be used in the dc servo motor is spark machine, manipulator, precise machine, etc. Can be equipped with 2500 p/R high profile degree and the specification of the encoder velometer, can add more with reducer, the mechanical device with reliable accuracy and high torque. Good speed regulation, the unit weight and volume, the highest output power, greater than the communication machine, more than stepper motor. Shake small torque of multistage structure.
