Goodrive30 Series VFD Fault tracking
-116-
For VFDs with an incoming voltage of 1PH/3PH 220V AC, you can use a 220VAC/2A voltage
regulator. Both 1PH and 3PH VFDs can be charged with a 1PH voltage controlled power
supply (connect L+ to R, and N to S or T). All the DC bus capacitors share one rectifier, and
therefore they are all charged.
For VFDs of a high voltage class, ensure that the voltage requirement (for example, 380 V) is
met during charging. Capacitor charging requires little current, and therefore you can use a
small-capacity power supply (2A is sufficient).
6.1.3.2 Electrolytic capacitor replacement
Read the safety precautions carefully and follow the instructions to
perform operations. Otherwise, physical injuries or damage to the device
may be caused.
The electrolytic capacitor of the VFD must be replaced if it has been used for more than
35,000 hours. For details about the replacement, contact the local INVT office.
6.1.4 Power cable
Read the safety precautions carefully and follow the instructions to
perform operations. Otherwise, physical injuries or damage to the device
may be caused.
1. Stop the VFD, disconnect the power supply, and wait for a time no shorter than the waiting
time designated on the VFD.
2. Check the connection of the power cables. Ensure that they are firmly connected.
3. Power on the VFD.
6.2 Fault handling
Only trained and qualified professionals are allowed to carry out the work
described in this chapter. Operations should be carried out according to
the instructions presented in "Safety precautions".
6.2.1 Indications of alarms and faults
The fault is indicated by indicators (see "Keypad operation procedure"). When TRIP indicator
is on, the alarm or fault code displayed in the keypad indicates the VFD is in exception state.
The function codes P07.27 to P07.32 record the types of the last six faults. The function codes
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. This chapter covers most of the alarms and faults,
and their possible causes and corrective measures, if users cannot figure out the alarm or fault
causes, contact local INVT office.
6.2.2 Fault reset
You can reset the VFD through the STOP/RST key on the keypad, digital inputs, or by cutting
off the VFD power. After faults are removed, the motor can be start again.
