Reason
1. High input voltage
2. Regenerative energy
from the motor is too large
1. Dec time is too short
2. Load is too big
3. High input voltage
1. High input voltage
2. Load is too big
1. Low input voltage
1. Low input voltage
2. Wrong setting of motor
parameter
3. Motor locked rotor or
sudden big change of load
to small load
4. The power of motor is
too small
1. Acc time is too short
2. Restart the motor when it
is decelerating
3. Low input voltage
4. Load is too big
1. Loss of phase occurred
in power supply
1. Loss of phase occurred
in output side of main

Solution
•
Check the power supply
•
Avoid restarting the motor until it stops
completely
•
Increase Dec. time
•
Reduce load or use higher power
controller
•
Check the power supply
•
Install input reactor
•
Increase braking
•
Check the power supply
•
Check the power supply
•
Set the rated current of motor properly
•
Check the load, adjust the value of
torque boost
•
Select proper power motor
•
Prolong Acc time
•
Avoid restarting the motor until it stops
completely
•
Check the power supply
•
Select bigger capacity controller
•
Check the wiring, installation and the
power supply
•
Check the output wiring, cable and
motor
