In the field of hydraulic servo control, precise, reliable, and flexible motion control is the core of improving the performance of mechanical equipment. For applications with strict requirements such as plastic processing machinery, press machines, specialized machine tools, and even rail vehicles, a shaft control system that can cope with complex working conditions, provide powerful programming capabilities, and integrate multiple controller types is crucial. Bosch Rexroth's VT-HNC100 digital axis controller was born for this purpose. This article will deeply analyze the hardware characteristics, software configuration process, core control algorithms, NC programming practices, and key fault diagnosis methods of HNC100 from the perspective of an engineering technician, aiming to provide a comprehensive application guide for engineers engaged in hydraulic system integration, debugging, and maintenance.
When the 'no error' output signal is lost, the system enters a safe state, which is the primary clue for troubleshooting.
Sports performance issues:
Shake or crawl: Check the gain (KP) of the position controller, which may need to be adjusted. Attempt to activate the "residual voltage" principle or adjust zero point compensation.
Endpoint oscillation: Reduce the proportional gain or increase the differential (if used) effect, check the speed feedforward setting.
Pressure overshoot: Adjust the PID parameters of the pressure controller, especially the integration time. Check the response speed and installation position of the pressure sensor.
Program logic error: Using WIN-PED's online debugging function. It is possible to execute NC programs in single steps, monitor R parameters, flag bits, and I/O status, and observe the execution of motion instructions such as G01 and G26. Use the M00 instruction to set breakpoints and analyze program flow.
