Anyone have any experance with power flex 70 drives,

The drive has a maximum current capacity, based on the ability of the power components and heat sink to dissipate heat resulting from current flow. If something is trying to pull more current for too long and that capacity is exceeded, the drive shuts down to protect itself. Determining what it is or was that caused that to happen is your challenge. Generally it is one of three classes of causes; a misapplication, a failure in the drive or a failure in the load. From the information you have given so far, there is no way to take it further than that. But if it was a failure in the drive, sometimes this is the final fault to show up, because it is the one that shut the drive down. Look in the fault history first to see of there were any events that preceded this.

This drive is inside a blower, , the dirty air goes past the heat sinc ,
And you can't even see the drive.
It in it own small compartment.

The filter is after the drive so it is sucking the dirty air in.
Worst design ever.
Left it for the night shift.lol.
