Your problem probably is not an additional charge. It is that at least in Florida if a judge suspended your sentance and you violate probation and the court finds you guilty of the violation unless the prosecutor agrees you go to jail for the time of the suspended jail time.
If the original sentences were to run concurrent then they will stay that way. This is not a new sentencing hearing. You will not get additional time for absconding, but this will be a probation violation worthy of activating your sentence. If this is a first violation, the judge might also simply give you a few days active and extend your probation. He can also out you on intensive probation or house arrest. There are lots of options.
