Its all about the de-rate factor, the given 200 volts is found as follows;
240v * (50Hz/60Hz) = 200v this not mean you should run this motor on 200v, it means on 50Hz it has the performance as of running on 200v.
Example; to replace a 1 kw 240v 60Hz motor to run on 50Hz you need to replace it with a 1kW * (60Hz/50Hz) = 1.2 kW 240v 60Hz motor.
