B&R Servo Drive ACOPOS 1090 Overload Failure Repair Quick Fixes

Generally speaking, the overcurrent protection of B&R servo drives is caused by the internal failure of the drive. Of course, there are special reasons, such as in the case of normal load drive or overcurrent protection, then most of this situation is caused by the overcurrent detection circuit, such as the current detection circuit, or sampling resistors and sensors of the overcurrent reasons.

Servo drive overcurrent fault checking steps can generally be divided into four steps：

Firstly,  it is necessary to determine whether the load of the drive meets the normal operating conditions.

Secondly,  it is to determine whether the drive itself is normal.

Then,  to determine the setup parameters of the drive and acceleration and deceleration process or load running process conditions are not matched; determine whether the drive wiring is normal.

Specific maintenance steps can correspond to the inspection steps. For example, in the inspection of a link is not normal, you can repair for a certain link.
