Fault tracking 71 - 104
Time Operational principle
• Add 75% rated voltage for 30 minutes
• Add 100% rated voltage for 30 minutes
Storing time more than 3
years
Use power surge to charge for the inverter
• Add 25% rated voltage for 2 hours
• Add 50% rated voltage for 2 hours
• Add 75% rated voltage for 2 hours
• Add 100% rated voltage for 2 hours
The right power surge for CV10 inverters is single phase 230V AC / 2A. All DC bus capacitors charge at the same time
because there is one rectifier. 2A is enough because the capacitor nearly does not need current when charging.
Change electrolytic capacitors
 Read and follow the instructions in chapter Safety Precautions . Ignoring the
instructions may cause physical injury or death, or damage to the equipment.
Change electrolytic capacitors if the working hours of electrolytic capacitors in the inverter are above 35000.
Please contact with SALICRU for detailed operation.
6.1.4 Power cable
 Read and follow the instructions in chapter Safety Precautions . Ignoring the
instructions may cause physical injury or death, or damage to the equipment.
1. Stop the drive and disconnect it from the power line. Wait for at least the time designated on the inverter.
2. Check the tightness of the power cable connections.
3. Restore power.
6.2 Fault solution
 Only qualified electricians are allowed to maintain the inverter. Read the safety
instructions in chapter Safety precautions before working on the inverter.
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. P07.27~P07.32 record the lastest 6 fault type and
P07.33~P07.56 record the operation data of the lastest 3 fault type. Using the information reference in this
chapter, most alarm and fault cause can be identified and corrected. If not, contact with SALICRU.
6.2.2 Fault reset
The inverter can be reset by pressing the keypad key STOP/RST, through digital input, or by switching the
power input. When the fault has been removed, the motor can be restarted.
6.2.3 Fault instruction and solution
Do as the following after the inverter fault:
1. Check to ensure there is nothing wrong with the keypad. If there is something wrong, please contact with SALICRU.
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.
