Most Common Signs of Industrial Drive Failures:
If failure signs are identified promptly, many serious problems can be prevented. Some of these signs are as follows:
One of these signs is the display of an error code on the drive screen. Advanced drives include internal error detection systems, and since each error code indicates a specific fault, the drive problem can be easily diagnosed. Of course, understanding the root cause of the error requires knowledge and experience in this field.
If the drive does not turn on after power is connected, it is very likely that the problem lies with the internal power supply or relay failures. Generally, one of the most common failure points is the switching power supply, which fails due to voltage fluctuations.
If you notice vibration and unusual noise from the motor, the cause may be incorrect parameter settings or issues with the IGBT switching.
Another common cause of drive failure is problems with the cooling fan, high ambient temperature, and clogged air filters. When the fan fails, the power components related to the drive are quickly damaged.
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.
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 | 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 widely used in many industries, and its main failures 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 expertise.
Inverter Repair Cost:
The truth is that a fixed amount cannot be set; the cost of drive repair depends on the type of fault and many factors must be considered, including:
The higher the drive power, the more expensive the parts and repair costs.
Some brands, such as Siemens and Schneider, have different parts prices.
The repair cost depends on the type of faulty part; for example, the IGBT module is one of the most expensive components.
