Yaskawa H1000 drive displays OL1 & OL2 alram after 25 minutes (running process) or so

the siemens 17KW motor gets very very warm ....

It was giving the OL1 fault then when i tried it again it given OL2 fault ....

the amps are in the range of 25.5 A to 31.5 A ..... Braking resistors are used in this process , its a main motor connected with the chain & gear system to run all the stations of a printing machine

what to check ? New machine, new motor & new drive about 3 months older

How to resolve it ?

thanks$$
