What is an SOC fault on the ATV320?

Issue:

SOC fault on ATV320 drive.

Product Line:

ATV320

Product Line:

All

Cause:

Clarification of product characteristics.

Resolution:

SOC indicates "Output Cut" status so its not a fault.

This is related to the Output Phase Loss function.

Output phase loss is used to detect when one or more phases of the motor are pulling no current (open connection to motor).

It also can detect an imbalance in current draw between phases and trigger a fault if the imbalance is too great.

By default the Output phase loss parameter is set to YES, which means the drive will fault on an Output Phase Loss fault if there is a phase loss or significant current imbalance on the motor leads.

The Output phase loss parameter can be changed to No , or OAC Output Cut.

When it is set to OAC, SOC is displayed when the function is triggered (no motor is detected when commanded to run or motor is disconnected while running).

In this mode, once an output phase loss is detected, the drive will stop the motor and display SOC on the screen but will not trigger a fault status.

When set to No the drive will not monitor for a phase loss or phase imbalance in the motor connections. External phase loss protection should be provided.

This is the standard setting on enclosed drives that have a full voltage bypass, because the overload relay provided with bypass provides that protection.
