Fault Descriptions

Flash Invalid

This fault indicates that the firmware checksum has failed. Use the Tools Program Flash

menu item from Emerson Motion Control PowerTools® to reprogram/upgrade the firmware

stored in flash memory. If this problem persists, call EMERSON Motion Control. A common

cause would be an interrupted F/W Flash upgrade (cable disconnected during an upgrade

process).

Watchdog Timer

The watchdog timer ensures that the firmware is operating normally. If the firmware fails to

reset this timer every 10 ms, the drive hardware will be reset, all inputs and outputs will be

cleared (“Off”), and a Watchdog Timer fault is generated.

Power Up Test

This fault indicates that the power-up self-test has failed. This fault cannot be reset with the

reset command or reset button.

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.

FM-3 Fault

A 3 will be displayed in the segment display on the E Series drive when the FM-3 experiences

a fault. See the table above for more information about the various faults.
