Unbalance current
1. Check whether there is output phase loss of motor cables, and please connect
the motor cables correctly if any mistakes.
2. Measure the resistance value among the motor cables, please replace the
cable if any deviation.
4
Current oscillation
1. Check whether there is a phase short circuit among the motor wires, please
connect the motor wires correctly if there any mistake.
2. Check whether the input motor nameplate parameters are correct, please
correct them if any errors.
3. Set the acceleration/deceleration time too large to casue current oscillation,
appropriately reduce F01.22 [acceleration time 1] and F01.23 [deceleration time
1].
4. Adjust F04.06 [oscillation suppression gain] according to the parameter
description.
5
Static learning current amplitude exceeds
the limit
1. Check whether there is a phase short circuit in the motor line, if there is an
error, please connect the motor line correctly
2. Check whether the input motor nameplate parameters and the number of
encoder cables are correct, please correct the errors.
3. Make sure the rated current of the motor is smaller than the output current
limit of the inverter.
6
U phase current overrun during static
learning
Check the U-phase motor connection, whether there is a phase-to-phase or
ground short circuit, please connect correctly if there is a mistake.
7
V phase current overrun during static
learning
Check the V-phase motor connection, whether there is a phase-to-phase or
ground short circuit, please connect correctly if there is a mistake.
8
W phase current overrun during static
learning
Check the W-phase motor connection, whether there is a phase-to-phase or
ground short circuit, please connect correctly if there is a mistake.
9
Continuous current overrun during
dynamic learning
1. Check whether there is a phase short circuit among the motor wires, please
connect the motor wires correctly if there is a mistake.
2. Check whether the input motor nameplate parameters are correct, please
correct if there is a mistake.
3. Make sure that the load carried by the motor does not exceed 50% of the
rated load.
4. Increase F01.22 [acceleration time 1] and F01.23 [deceleration time 1]
