8.1 What this chapter contains
The chapter tells you how to reset faults and check faults history of rectifier and inverter units. A complete list of alarms
and fault information as well as possible causes and corrective measures are presented in this chapter.
Only trained and qualified professionals are allowed to carry out the operations
mentioned in this chapter. Please carry out operations according to instructions
presented in chapter 1 Safety precautions.
8.2 Indications of alarms and faults
The fault is indicated by indicators (refer to the "Basic operation guidelines"). When the TRIP indicator is on, the alarm or
fault code displayed in the keypad indicates the power unit is in exception state. This chapter covers most of the alarms
and faults, and their possible causes and corrective measures, if you cannot figure out the alarm or fault causes, contact
local INVT office.
8.3 Fault reset
8.3.1 Rectifier fault reset
On the fault interface, you can reset the rectifier unit through DATA/ENT key on the keypad, digital inputs, or by cutting
off the rectifier unit power. After faults are removed, the rectifier unit can be started again.
8.3.2 Inverter fault reset
On the fault interface, you can reset the inverter unit through DATA/ENT key on the keypad, digital inputs, or by cutting
off the inverter unit power. After faults are removed, the motor can be started again.
8.4 Fault history
For the inverter unit, P07.27
–P07.32 record the types of the most recent six faults, and P07.33–P07.40, P07.41–P07.48,
and P07.49
–P07.56 record the running data of the inverter unit when the most recent three faults occur.
For the rectifier unit, P19.00
–P19.05 record the types of the most recent six faults, and P19.06–P19.13, P19.16–P19.23,
and P19.26
–P19.33 record the running data of the rectifier unit when the most recent three faults occur.
8.5 Faults and solutions
8.5.1 Rectifier faults and solutions
When a fault occurred to the rectifier unit, handle the fault as follows:
1. Check whether keypad display is improper. If yes, contact INVT or its local office.
2. If the keypad works properly, check the function codes in P19 group to check the fault record parameters to determine
the real state when the fault occurred.
3. Check the following table to see whether the exception state exists by solution.
