Key questions and answers

Question 1: What is the most common fatal mistake in the main circuit wiring of iG5A frequency converter? What consequences will it cause?

Answer: The most common mistake is to connect the power supply R/S/T to the motor terminals U/V/W. Consequence: Directly damaging the internal power module of the frequency converter, which cannot be repaired and is not covered by the warranty. Correct connection: Power → R/S/T, Motor → U/V/W.

Question 2: How to quickly restore the iG5A frequency converter to its factory default parameters? What is the operation path?

answer:

Enter FUN2 group (parameter starting with H)

Find H93 (parameter initialization)

Set to 1 (all initialized)

Press ENT to save, it will take effect after restarting

Applicable scenarios: parameter confusion, debugging exceptions, and changing application scenarios.

Question 3: What are the most common causes and solutions for overvoltage (OV) faults in frequency converters?

Answer: Common reasons:

The deceleration time is too short, and the feedback energy from the motor cannot be released

The power supply voltage is too high

The load inertia is large, and there is no brake resistor installed

Solution:

Extend deceleration time

Install braking resistor (B1/B2)

Check if the input voltage is within the rated range of * * ± 15% * *
