Frequently Asked Questions

Q: Trips overcurrent immediately when powered on?

A: Usually motor cable short-circuit, grounding issue or motor fault. Check cables and motor first.

Q: Trips overvoltage during deceleration?

A: High inertia load feeds back too much energy. Add a braking resistor or increase deceleration time.

Q: Motor vibrates and runs noisy?

A: Lower switching frequency, re-enter motor parameters, and avoid excessive torque gain.

Q: No communication or PLC control not responding?

A: Check baud rate, station ID and parity. Use shielded cable and route separately from power wires.

Q: Keypad blank, drive won't start?

A: Check input voltage for phase loss, loose terminals or blown internal fuse.

Q: Motor cannot reach rated speed?

A: Check if maximum frequency is limited, or motor rated frequency/speed is set incorrectly.

Q: Overload alarm under light load?

A: Wrong motor model, excessive torque boost, or poor cooling due to high ambient temperature.

Q: Can it directly replace old SK/DC series?

A: Yes if same power rating, but must re-wire and re-set parameters.

Q: Works with both 50Hz and 60Hz grids overseas?

A: Yes, as long as input voltage matches, no extra parameter changes needed.

Q: How to reset alarms quickly on site?

A: Press STOP + RESET on keypad, or power cycle the drive.

Q: Alarms randomly when connected to PLC?

A: Electrical interference. Separate communication and power cables, use ferrite cores and proper grounding.

Q: Can it drive servo or synchronous motors?

A: Yes, but requires encoder card for closed-loop vector control.
