Frequently Asked Questions

Is it genuine original?

All are original Danfoss products from official channels. Avoid cheap refurbished units.

Does it work with foreign voltages?

Most models support wide voltage 380-480V, compatible with EU, Asia, Middle East, Africa and Americas.

Can it work with other brand motors?

Yes, it works with standard induction motors and permanent magnet synchronous motors.

What's the difference between FC301 and FC302?

FC301 is standard general-purpose. FC302 is higher performance for cranes, tension control and heavy-duty applications.

Can it be used in high-temperature workshops?

Yes. With back-channel cooling, it runs stably at 50°C without derating.

Can it be installed outdoors directly?

Standard version is IP20 and must be installed in a cabinet. Choose IP54/IP55 for outdoor or wet environments.

Does it have CE, UL certification for export?

Yes, full series have CE, UL, cUL, RoHS, suitable for export worldwide.

Can it connect to Siemens, Mitsubishi PLCs?

Yes, it supports common communication protocols: Modbus, Profinet, CANopen, etc.

Is the energy-saving effect obvious?

Very obvious on fans and pumps, usually saving 10%-30% electricity.

Will it trip often if the grid is unstable?

It has good anti-fluctuation performance, works normally with ±10% voltage variation.

Does it have safety functions?

Most models come with STO (Safe Torque Off) as standard, no extra module needed.

How long is the service life?

Normally 8-12 years with proper use and regular dust cleaning.

Is it easy to copy parameters in bulk?

Yes, parameters can be copied via the control panel quickly.

Is overseas after-sales service available?

Yes, Danfoss has a global service network; local distributors can provide basic support.

How to protect it in dusty workshops?

Choose coated PCB versions, use cabinet filters, and keep cooling ducts clean.
