Frequently Asked Questions
When driving a permanent magnet motor, an "overcurrent" alarm occurs during startup. After eliminating motor wiring issues, what else could be the cause?
Most likely due to mismatched permanent magnet motor parameter configuration. Ensure the inverter's "Motor Type" is set to "Permanent Magnet Synchronous Motor" mode and accurately input rated power, current, speed, and field weakening coefficient from the motor nameplate.
When controlling a fan, noise increases significantly during low-speed operation with current fluctuations. How to solve this?
Optimize the V/F curve by selecting the dedicated "Fan/Pump" load type. Increase switching frequency to 6-8kHz (not exceeding 6kHz for models ≥55kW). Enable "Low-Speed Compensation" and increase output voltage below 20Hz to stabilize the motor magnetic field.
When communicating with a PLC via Modbus, parameter reading occasionally fails over 80 meters with shielded wiring. What could be the problem?
Verify communication parameters match exactly between inverter and PLC. Install 120Ω terminal resistors at both ends of the RS485 connection. Ensure shield grounding at one end only and route cables away from power sources to prevent electromagnetic interference.
For lift pumps in sewage treatment, how to set automatic speed adjustment using float level switches?
Connect level signals to DI1 (stop), DI2 (preset speed 1 - medium level), and DI3 (preset speed 2 - high level). Configure terminal functions accordingly and set acceleration/deceleration times to 10-15 seconds to prevent pump impact.
After six months of operation, an "overheating" alarm occurs despite normal room temperature and clear airflow. What is the reason?
Check internal cooling fan operation and motor load conditions. Clean heat sinks if dusty. Verify actual current readings - if approaching rated current, inspect for pipeline resistance increases from valve jamming or filter blockages.
