Advantages and disadvantages of Delta's open-loop and closed-loop control
1. Open-loop control
There is no reverse connection between the controller and the controlled target, and the control is carried out in one direction.
Strengths: Simple, stable and reliable. If the characteristics and parameter values of the components that make up the system are relatively stable, and the external disturbance is small, the open-loop control energy
Enough...

Selection of braking resistors for Delta inverters
1. The necessity of braking resistance
If the regenerative energy that occurs during deceleration and descent in the application is too large, there is a possibility that the voltage of the main circuit inside the inverter will rise, causing damage.
Because usually the inverter has a built-in overvoltage maintenance function, the main circuit overvoltage (O...

Troubleshooting of small electromagnetic relay cores - Delta
The main problems of the iron core of the small electromagnetic relay are that the armature cannot be sucked after being electrified:
This may be due to broken coils, foreign matter between the moving and static cores, and low power supply voltage. It should be patched on a case-by-case basis.
When energized, the armature is noisy:
This may be because of the ...
