Limit on amount secured in charges

Dear Friends,

I would like to know if there is any limit on the Amount secured in the filing of charges. that is to say any limit upto which a company can avail the amount on property charged, or it can avail any amount as bank guarantee on the property charged.??

Any Section for this limit (if any).??

Early repl is awaited.

Thanks in advance.
