Analysis of misunderstandings in the application of Delta inverters
The capacity selection of the inverter is based on the rated power of the motor
Myth: The capacity selection of the inverter is based on the rated power of the motor
Compared with the motor, the price of the frequency converter is the most expensive, so under the premise of ensuring safe and reliable operation, the frequency conversion can be reasonably reduced.

Productivity maintenance tips for Delta drives
1. When the Delta inverter breaks down in the future, it is best not to hand it over to someone who has no experience in repairing the inverter to repair the inverter, otherwise it may get worse and worse. Sometimes it's about to fuse, be sure to check whether there is a problem with the module, some electricians have not experienced it, and immediately install a good fast melt (definitely not ...

Analysis and correction of the cause of Delta servo drive alarm
Analyze and correct the cause of Delta servo drive alarms.
Control current and undervoltage protection.
Alert Number: 11.
Reason: The voltage at the end of the dynamic DC bus is lower than the specified value. Due to the instantaneous shortage of power supply capacity, the control voltage is too low.
Measure: Measure the DC bus ...

The parameter that needs to be set for the inverter - Delta
There will be some difference between the parameter setting of the inverter at the factory and the requirements of practical application. Therefore, the reasonable setting of the inverter parameters is directly related to whether the inverter can be used normally, which is of decisive significance.
General-purpose inverters generally have dozens or even hundreds of functional parameters.

Basic conditions for Delta UPS uninterruptible power supply
1. Visually inspect the UPS and battery (or other energy storage) equipment for obstacles, and properly cool the surrounding area.
2. Ensure that there is no abnormal operation or positive warning on the UPS panel, such as: overload or overdischarge of the battery close to it.
3. Check if there is battery corrosion or other shortcomings ...

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...
