Drive repair in Tehran | Inverter repair in Tehran with full specialization:

The first step in drive troubleshooting is identifying faults and examining the causes of errors. Since accurate initial diagnosis and repair or replacement of parts require sufficient skill and knowledge in this field, you should contact a specialized drive repair center if an error occurs. For specialized drive repair in Tehran, contact Rapco.

Most common signs of industrial drive failure:

If failure signs are identified promptly, many serious problems can be prevented. Some of these signs are as follows:

1. One sign is the display of an error code on the drive screen. Advanced drives include an internal error detection system, and since each error code indicates a specific fault, the drive problem can be easily identified. Of course, understanding the main cause of the error requires knowledge and experience.
2. If the drive does not turn on after power is connected, it is very likely that the problem is with the internal power supply or relay failure. Generally, one of the most frequent failure points is the switching power supply, which occurs due to voltage fluctuations.
3. If you notice vibration and unusual noise from the motor, the cause may be incorrect parameter settings or a problem with the IGBT switching.
4. Another common cause of drive failure relates to cooling fan issues, high ambient temperature, and clogged air filters. If the fan fails, the drive's power components are quickly damaged.
5. When the DC bus voltage exceeds its allowable limit, an overvoltage error occurs. This failure can be caused by a faulty braking resistor or input voltage fluctuations.
6. When temperature sensors detect excessive heat, this error appears. The main causes of this error are fan failure and dust accumulation.

Answering one of the most frequently asked questions | The main difference between AC and DC drive repair

One of the most common types of drive repair is AC drive repair. This type of drive is used in most industries, and the main causes of failure are related to the IGBT, capacitors, and power section. DC drive repair is much more specialized than AC drive repair because this drive is used in heavy industries such as steel and furnaces, and its repair requires more knowledge.

Inverter repair cost: The truth is that a fixed amount cannot be set, and the cost of drive repair depends on the type of fault and many factors must be considered, including:

1. The higher the drive power, the more expensive the parts and repair costs are.
2. Some brands like Siemens and Schneider have different parts prices.
3. The cost of drive repair depends on the faulty part; for example, the IGBT module is one of the most expensive parts.
