6.1.3 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 Universal Motors.
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 light. 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 kepad. If not, please contact with Universal Motors.
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.

Over-current when
acceleration
1. The acceleration or
deceleration is too fast.
2. The voltage of the grid is
too low.
3. The power of the inverter is
too low.
4. The load transients or is
