Goodrive100 inverters

6.2.1 Alarm and fault indications

Fault is indicated by LEDs. See Operation Procedure. When TRIP light is on, an alarm or fault message
on the panel display indicates abnormal inverter state. Using the information given in this chapter, most
alarm and fault cause can be identified and corrected. If not, contact with the INVT office.

6.2.2 How to reset

The inverter can be reset by pressing the keypad key STOP/RST, through digital input, or by switching the
power light. When the fault has been removed, the motor can be restarted.

6.2.3 Fault history

Function codes P07.25~P07.30 store 6 recent faults. Function codes P07.31~P07.38, P07.39~P7.46,
P07.47~P07.54 show drive operation data when the latest 3 faults occurrs.

6.2.4 Fault instruction and solution

Do as the following after the inverter fault:
1. Check to ensure there is nothing wrong with the kepad. If not, please contact with the local INVT office.
2. If there is nothing wrong, please check P07 and ensure the corresponding recorded fault parameters to
confirm the real state when the current fault occurs by all parameters.
3. See the following table for detailed solution and check the corresponding abnormal state.
4. Eliminate the fault and ask for relative help.
5. Check to eliminate the fault and carry out fault reset to run the inverter.
