How to fix encoder reversal on INVT Goodrive300-01A DC Drives?
If your INVT DC Drive is showing encoder reversal, it means the encoder speed signal is contrary to the motor running direction. Reset P20.02 encoder direction to resolve this.
Why is there overvoltage at acceleration in INVT Goodrive300-01A?
If your INVT DC Drive is experiencing overvoltage during acceleration, the input voltage might be abnormal, so check the input power. Alternatively, there might be large energy feedback. In this case, verify if the deceleration time of the load is too short or if the motor starts during rotation. Installing dynamic brake units might also be necessary.
How to fix inverter unit U phase protection in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive displays an inverter unit U phase protection error, it could be due to several reasons. The acceleration might be too fast; try increasing the acceleration time. There could be internal damage to the IGBT of that phase, requiring a power unit replacement. Improperly connected drive wires could also be the cause, so check the wiring. Finally, strong interference from peripheral equipment might be the culprit; investigate and eliminate any interference sources.
What causes temperature alarm in INVT Goodrive300-01A?
If your INVT DC Drive is showing a temperature alarm, it could be because the actual temperature detected by PT1 is higher than the alarm temperature set by P18.20. Check whether the fan control parameters are correct and whether the fan operates normally.
What does encoder Z pulse offline mean in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive displays an encoder Z pulse offline error, it means the Z signal wire is disconnected. Check the wiring of the Z signal wire.
What causes temperature pre-alarm in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive is showing a temperature pre-alarm, it could be because the actual temperature detected by PT1 is higher than the pre-alarm temperature set by P18.19. Check whether the fan control parameters are set correctly and whether the fan operates normally.
How to fix parameter download error on INVT DC Drives?
If your INVT DC Drive is experiencing a parameter download error, it could be due to a poorly contacted or disconnected keypad line. Check the environment and rule out the interference source. The keypad wire might be too long or suffering from strong interference; replace the hardware and ask for maintenance service. Alternatively, the storage data in the keypad could be wrong, so re-copy the data in the keypad.
What does to-ground short mean on INVT Goodrive300-01A?
If your INVT DC Drive indicates a 'To-ground short,' it means the VFD output is short-circuited to ground. Check whether the motor wiring is normal and if the motor is short-circuited to ground.
What causes pressure alarm in INVT Goodrive300-01A?
If your INVT DC Drive is showing a pressure alarm, it could be because the actual voltage detected by P1 is larger than the alarm voltage set by P18.18. Check whether the solenoid valve is normal and whether the pressure control parameters are set correctly.
What does external fault mean on INVT Goodrive300-01A?
If your INVT DC Drive displays an external fault, it means the S external fault input terminal is active. Check the external equipment input to resolve this issue.
