Check the specification plate on the motor. If 220/440V or 230/460 is given, just rewire the motor from star to delta connection. Check for control supply voltage also. On the terminalboard you will find 6 bolts ( 3 rows with 2 bolts), all connectet to the motor windings; 1 of each row to the supply. If 3 bolts of a line are connectet to the supply and the opposite 3 bolts are jumpered in line, that wiring is called star; if always 2 bolts of a row are jumpered and at the same time connectet to the supply it is a delta connection. That means a star connection is used for higer voltage and a delta connection for lower voltage. Do not touch the origin wiring of the motor windings.
