Correct test procedure for servo motor
How do you know the servo motor? Some customers report that they do not know how to operate the test after buying the servo motor. The following describes the steps for correct testing of the servo motor:
First test the motor first, do not need to connect any circuit, short-circuit any two wires of the motor together, turn the motor shaft by hand, feel the resistance, then OK.
The second step is to connect the drive to the power supply according to the drawing (for example, using a voltage regulator, from 100V to 220V, for fear that the drive is 100V), power on, the drive is normal, there is an error message display, according to the manual, the encoder is displayed. Faulty error, this is normal, there is no encoder connected yet.
The third step is to connect the encoder and turn it on again. No errors are displayed.
In the fourth step, follow the instructions to set up the drive. For example, the "speed control mode" is set, then the potentiometer is turned on, and the motor does not rotate. According to the instructions on the manual, adjust the toggle switch. After the “Servo-ON” is toggled, the motor is locked at once, OK! Then turn the potentiometer so that the SPR/TRQR input pin has voltage, good! The motor is turning. The number of revolutions on the servo drive reached 1000, 2000, and 3000, and finally reached more than 4,000 revolutions. The recommended size on the manual is 3000 rpm, and there may be some problems with high speed.
In the fifth step, the servo drive is reset, and the position control mode is changed. The motion control card (or MACH3, connected to the parallel port of the computer) is connected to the pulse and direction interface, and the motor is also rotated! At an output rate of 500 Kpps, 3000 rpm is shown on the drive. Both forward and reverse can be controlled by themselves.
Finally, adjust the motion control card and make a small connection board. The LED array on the board is used for test output. The socket is connected to the two-phase encoder, the other socket is the output pulse/direction, and the switch and button are the test I/O input.
