Hi, i have a month now that i am encounter a problem with a drive hcs03.1e-w0070-a-05-nnbv . The build that i have is the drive with a card CSB02.1A-ET-EC-NN-NN-NN-NN-FW and an external resistor. I am using often this drives at the same build but never have a problem before at the machine. Suddenly one of the machines that i am using the Drive started has the error ''F2816 Softstart fault power supply unit'' . The error seems that has not any pattern and can be appeared randomly. The steps that i have done until now to fix the problem without any luck is :
1) Measuring the main voltage( seems Ok)
2) Changing the Drive with a New one ( Error F2816 remains)
3) Load the initial parameters at the drive and after load again my backup (error remains)
Attached is the full backup of the Drive with errors F2816 inside. I will appreciate any help .
