Overload 2

1. Reduce the motor load.

 

 

2. Adjust the over-torque detection setting to an

 

 

Motor overload.

 

 

 

appropriate setting (Pr.06.03 to Pr.06.05).

 

 

 

 

 

 

Software protection failure

Return to the factory.

1. When the external input terminal (B.B) is active,

 

 

External Base Block.

 

the AC motor drive output will be turned off.

 

 

(Refer to Pr. 08.07)

2.

Deactivate the external input terminal (B.B) to

 

 

 

 

operate the AC motor drive again.

 

 

 

1.

When multi-function input terminals (MI3-MI9)

 

 

 

 

are set to external fault, the AC motor drive

 

 

External Fault

 

stops output U, V and W.

 

 

 

2.

Give RESET command after fault has been

 

 

 

 

cleared.

 

 

 

1.

Short-circuit at motor output: Check for possible

 

 

 

 

poor insulation at the output lines.

 

 

 

2.

Torque boost too high: Decrease the torque

 

 

Over-current during

 

compensation setting in Pr.07.02.

 

 

3. Acceleration Time too short: Increase the

 

 

acceleration

 

 

 

Acceleration Time.

 

 

 

 

 

 

 

4.

AC motor drive output power is too small:

 

 

 

 

Replace the AC motor drive with the next

 

 

 

 

higher power model.

 

 

 

1.

Short-circuit at motor output: Check for possible

 

 

 

 

poor insulation at the output line.

 

 

Over-current during

2. Deceleration Time too short: Increase the

 

 

 

Deceleration Time.

 

 

deceleration

 

 

 

3.

AC motor drive output power is too small:

 

 

 

 

 

 

 

Replace the AC motor drive with the next

 

 

 

 

higher power model.

 

 

 

1.

Short-circuit at motor output: Check for possible

 

 

 

 

poor insulation at the output line.

 

 

Over-current during steady

2. Sudden increase in motor loading: Check for

 

 

 

possible motor stall.

 

 

state operation

 

 

 

3.

AC motor drive output power is too small:

 

 

 

 

 

 

 

Replace the AC motor drive with the next

 

 

 

 

higher power model.
