FAQS

1. Most of them are incorrect parameter settings. Check the parameter modification first.
2. Check whether the wiring is wrong or short-circuit leakage.

1. Frequency converter parameter torque increase
2. The setting of the motor or the motor connection is aging and foreign objects are stuck.
3. The motor itself is broken and can't be started.

Using equipment and scenarios, heavy-load equipment should also choose a heavy-load frequency converter, and even increase the power of the frequency converter. For example, the frequency converter for 220KW crusher requires a 255KW heavy-load frequency converter.
High-temperature and dust-resistant frequency converters should be used in tropical areas such as Africa.
Russia and other cold regions should choose frequency converters with high low temperature resistance.

We provide graded protection solutions. Standard products meet the IP20 protection level; for harsh environments, IP40, IP54 or even higher protection level models can be selected, and support three anti-coatings (moist moisture-proof, anti-salt fog, anti-mold). Our technical team can provide on-site condition evaluation and give non-standard transformation suggestions (such as independent air ducts, external radiators, sealed control boxes, etc.) to ensure that the core circuit is physically isolated from the harsh environment.

Need. Electrolytic capacitors and cooling fans are common consumable parts, and early replacement can avoid sudden downtime. We provide:
Annual inspection: Engineers use infrared thermal imaging and ESR table to check the capacitance status and issue equipment health reports.
Predictive maintenance: optional Internet of Things module, real-time monitoring of operating data, prediction of potential faults (such as fan speed decline, capacitance value attenuation), and early warning 3 months in advance

Yes, but be careful. It must be ensured that the total rated current of all motors does not exceed the rated output current of the frequency converter, and it is better to keep a 10% margin -6. It is recommended to use V/F control, and it is best to install a thermal relay for separate protection for each motor.
