Goodrive18 series two-in-one VFD Troubleshooting
-104-
Step 2 Check the power cable connection and ensure the firmness.
Step 3 Power on the VFD.
6.2 Fault handling
Only well-trained and qualified professionals are allowed to perform the
work in this section. Follow the instructions in "Safety precautions".
6.2.1 Alarm and fault indication
When the TRIP indicator is on, the alarm or fault code displayed on the keypad indicates that
an exception occurs on the VFD. The function codes from P07.27 to P07.32 record the types
of the last six faults. The function codes from P07.33 to P07.40, P07.41 to P07.48, and P07.49
to P07.56 record the running data of the VFD at the last three faults, respectively. You can find
out causes and solutions for most of the alarms or faults based on the information provided in
this chapter. If you cannot find out the cause of an alarm or fault, contact the local INVT office.
6.2.2 Fault reset
The VFD can be reset by pressing the keypad key STOP/RST, through digital input, or by
cutting off the VFD power supply. When the fault has been removed, the motor can be
restarted.
6.2.3 Faults and solutions
Do as follows after a VFD fault occurs:
Step 1 Check whether the keypad display is normal. If not, contact the local INVT office.
Step 2 If there is no exception, check the corresponding fault record parameters in P07 to find
the real state when the fault occurred.
Step 3 See the following table for a detailed solution.
Step 4 Eliminate the fault or ask for technical support.
Step 5 Ensure the fault is handled, and carry out fault reset to run the VFD.
Note:
If Goodrive18 series two-in-one VFD encounters a fault, the keypad prefixes the fault code
with "P-" or "F-" to distinguish whether #1 inverter unit (group P) or #2 inverter unit (group
F) encounters a fault. If a fault code contains four digits by default, the "-" sign may be
deleted depending on the fault code length. For example, the PIDE fault on #1 inverter unit
is displayed as "PPIDE", while the OV1 fault on #2 inverter unit is displayed as "F-OV1". In
addition, there is no distinguishing measure for the LInCE communication fault.
When one inverter unit encounters a fault, you can choose whether to enable the other
inverter unit to report the fault and stop by setting the function codes P14.15 and F14.15.
