Specification

NVM Invalid

At power-up the drive tests the integrity of the non-volatile memory. This fault is generated if the contents of the non- volatile memory are invalid.

Invalid Configuration

This fault will occur if the digital board in the drive does not match the power board settings. It is only useful during manufacturing. A drive with this fault should be returned for service.

Drive Overtemp

Indicates the drive IGBT temperature has reached an over temperature condition. This fault is not currently implemented in the EP drive.

Power Module

This fault is generated when a power stage over-temperature, over-current or loss of power stage logic supply occurs. This can be the result of a motor short to ground, a short in the motor windings, a motor cable short or the failure of a switching transistor.

High DC Bus

This fault will occur whenever the voltage on the DC bus exceeds the High DC Bus threshold. The most likely cause of this fault would be an open external shunt, a high AC line condition, or an application that requires an external shunt (e.g., a large load with rapid deceleration) but none is installed.

High DC Bus Threshold

Epsilon EP

415 Vdc

Low DC Bus

This fault will occur whenever the voltage on the DC bus drops below the Low DC Bus threshold. The most likely cause of this fault is a reduction (or loss) of AC power. A 50 ms debounce time is used with this fault to avoid faults caused by intermittent power disruption. With an Epsilon EP drive, the low DC bus monitoring can be disabled. In an EP-B and EP-I this fault is disabled by clearing the check box on the Faults view, and for an EP-P the check box is located on the Advanced view

Low DC Bus Threshold

Epsilon EP

60 Vdc

Encoder State

Certain encoder state transitions are invalid and will cause the drive to report an encoder state fault. This is usually the result of noisy encoder feedback caused by poor shielding. For some types of custom motors it may be necessary to disable this fault. With an Epsilon EP drive, the Encoder State monitoring can be disabled. In an EP-B and EP-I this fault is disabled by clearing the check box on the Faults view, and for an EP-P the check box is located on the Advanced view.
