Hi all
I am working on a retrofit project.
There is one backup pump with Powerflex 753 drive controlled by 2 different PLCs(one 1756-L63 ,one 1756-L71 , have 1756-DNB on both sides)
We are using 20-COMM-D adapter on Powerflex 753 and work well via Devicenet.
However, there is one requirement from the customer to simulate in the case of power loss.
When the drive was on standby and cut power, there is no issue, and could be back online after the power was back.
But when we cut the power during the drive is controlled by PLC and recover the power back, the drive will disconnect and can't back online automatically.
I also use RSNetWorx to check the DeviceNet network, and the drive can't be scanned at the time.
The 1756-DNB and the drive also didn't indicate any error.
Any suggestions would be greatly appreciated
