  1. How Is A VFD Maintained?

  2. 1. Installation If the VFD is installed on a vibrating object, the main circuit connection screw can become loose. In turn, numerous VFDs reportedly suffered damage, according to our technical assistance.

  3. 2. Wiring installation To make sure that the damage is not too severe in the event of a short circuit, it is advisable to install an air valve to prevent the current value, which shouldn't be too high. You shouldn't ground the "N" end. In addition, electromagnetic waves will interact with the control panel if the control line is too long, frequently leading to malfunction and damage. If the control line is longer than 2 metres, shielded wire is recommended. Installation of contactors near to a variable frequency drive (VFD) should be avoided because they considerably interfere with it and cause problems.

  4. 3. Braking mechanism To achieve frequent emergency braking, it is advised to use an additional brake or mechanical brake. Otherwise, the inverter will be often influenced.

  5. 4. A fan that cools It is advised to add a cooling fan on the motor if the VFD driver routinely runs at low speeds less than 15Hz. For more details about Leroy somer repair, look out.

  6. 5. Place of installation Dust and humidity are the two most dangerous enemies of a VFD. It is advised to put a VFD in an area with air conditioning or in an electrical cabinet with a dust filter. Radiator and circuit board dust cleaning on a regular basis is advised. After a prolonged period of inactivity, blow a hairdryer across the circuit board before re-connecting it to power.

  7. 6. A power supply Voltage instability makes the VFD more vulnerable to harm in firms that rely on generator electricity. In this situation, the VFD must be protected using a voltage stabilizer or overvoltage protection mechanism.

  8. 7. Lightning protection Even if it happens infrequently, it is important. The VFD sustains significant damage when struck by lightning. The VFD for constant pressure water delivery system is most likely to be struck by lightning since it has a thunder leading pipe in the sky.

  9. 8. Minimize interference from electromagnetic sources. To avoid electromagnetic interference, the input, output, and control lines should be wired using insulated wire and appropriately. It will have functions that are incompatible if the wiring strategy is improper. Please wrap the carrier frequency in an iron tube with a filter to lower it if at all possible.

  10. 9. Correct Send the VFD to an expert in electronics repair if it malfunctions. An untrained engineer could make things worse. Please send the VFD back for service if the warranty is still in effect. Additionally, you can discover more about the VFD repair' troubleshooting manual. Please contact VFD repair if you have any queries regarding how to maintain a VFD.
