How to repair servo drives _ Servo drive repair tips
Characteristics of servo drives
1. The servo drive software program mainly includes the main program, interrupt service program, and data exchange program.
2. The main program of the servo driver is mainly used to complete system initialization, LO interface control signals, and register settings for various control modules within the DSP.
3. After all initialization work of the servo drive is completed, the main program enters a waiting state and waits for the occurrence of interrupts in order to adjust the current loop and speed loop.
4. After all initialization work of the servo drive is completed, the main program enters a waiting state and waits for the occurrence of interrupts in order to adjust the current loop and speed loop.
5. The initialization of servo drivers mainly includes the initialization of DsP cores, setting of current and speed loop cycles, PWM initialization,
4M startup, ADc initialization and startup, QEP initialization, initialization of vector and permanent magnet synchronous motor rotor initial positions,
multiple sampling of servo motor phase currents, determination of zero offset of phase currents, initialization of current and speed P regulation, etc.
6. PWM timing interrupt programs are used to sample and calibrate the two-phase currents ia and ib of Hall current sensors A and B, as well
as calculate the rotor magnetic field orientation angle based on the principle of magnetic field orientation control, and generate PWM signals to control the position and velocity loops.
7. The power drive protection interrupt program is mainly used to detect the fault output of intelligent power modules.
8. The zero pulse capture interrupt program of the photoelectric encoder can accurately capture the feedback zero pulse of the encoder, thereby obtaining the
correction value of the vector transformation orientation angle of the AC permanent magnet synchronous motor.
9. The data exchange program mainly includes communication programs with the upper computer, reading of EEPRoM parameters, digital display programs, etc.
