What causes pressure alarm in INVT Goodrive300-21 Inverter?
The pressure alarm in your INVT Inverter is triggered when the actual pressure detected by P1 is larger than the alarm pressure set by P18.18. Check if solenoid valve is normal and check if pressure control parameters are set correctly.
What to do if INVT Goodrive300-21 Inverter shows overvoltage during acceleration?
If the INVT Inverter shows overvoltage during acceleration, it could be due to the following reasons: * Check the input power if there is an exception occurred to input voltage. * Check whether load DEC time is too short, or the motor starts during rotating, or additional dynamic brake components is required because of large energy feedback.
Why INVT Inverter shows motor overload?
The INVT Inverter might show a motor overload due to several reasons: * If the grid voltage is too low, check the grid voltage. * If the motor rated current is set incorrectly, reset the motor rated current. * If the motor stall occurs or the load transient is too large, check the load and adjust the torque boost quantity.
What to do if INVT Inverter has RS485 communication fault?
If your INVT Inverter is experiencing an RS485 communication fault, consider the following: * Ensure the baud rate is set properly. * Check the wiring of communication interfaces for any faults. * Verify the communication address is set correctly. * If communication suffers from strong interference, replace or change the wiring to enhance the anti-interference capacity.
What to do if INVT Inverter shows bus undervoltage fault?
If the INVT Inverter shows a bus undervoltage fault, check the grid input power because the voltage of the grid may be too low.
How to troubleshoot phase loss on input side of INVT Inverter?
To troubleshoot phase loss on the input side of your INVT Inverter: * Check the input power if phase loss or violent fluctuation occurred on input R, S, T. * Check the installation wiring.
What to do for handshake failure on INVT Inverter?
If you're experiencing a handshake failure on your INVT Inverter, check whether the handshake between the Plott controller and inverter is performed according to the handshake protocol and check whether P15.10 is set properly, because the handshake process may timeout.
What does temperature alarm mean on INVT Goodrive300-21?
The temperature alarm in your INVT Inverter is triggered when the actual temperature detected by PT1 is larger than the alarm temperature set by P18.20. Check if control parameters of the fan are set correctly; Check if the fan operates normally; The fan power is too small for effective cooling; Check if there is lubricating oil.
What does external fault mean on INVT Inverter?
An external fault on your INVT Inverter indicates that S external faulty input terminal action. Check external device input.
How to resolve PID feedback offline fault in INVT Inverter?
To resolve a PID feedback offline fault in your INVT Inverter: * Check PID feedback signal wires because PID feedback may be offline. * Check PID feedback source because PID feedback source may disappear.
