What should we do when error NTC occurs? | Shihlin Electric

NTC: The inverting part of IGBT module overheat 1. Check whether the fan is running normally, clean up the foreign objects on the fan that might affect its cooling effect. 2. Reduce the carrier wave. Set P.72=2. 3. Reduce the motor load to decrease the inverter output current. 4. If the temperature of the inverter installation environment is too high, please install more heat dissipation devices on the control cabinet. 5. Check whether the air channel of inverter has been blocked by the dust. Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
