Fixed Term employment - how many times renewal permitted for one employee?

According to the notification to amend the order, words “fixed-term employment in apparel manufacturing sector” will be replaced by “fixed-term employment” meaning that facility would be available for all sectors.
My query is how many times renewal permitted for one employee?

Fixed-term employment is a contract in which a company or an enterprise hires an employee for a specific period of time. In most case it is for a year but can be renewed after the term expires depending on the requirement.
Under the fixed-term employment contract, the payout or the payment is fixed in advance and is not altered till the term expires. However, such contracts cannot be given for routine jobs. It is usually given out for jobs which are temporary. It cannot be used to replace existing employees, if he or she is on a long leave.
In IT companies, sometimes professionals are hired on contractual basis to complete a specific project.
