Two technicians are replacing an induction motor on a water pump into the fermentation vats in Elsinor brewery. The old American motor was rated at $240$ vac, $60Hz,6HP,1800rpm.$ The new European motor is rated at $240$vac,$50Hz,7HP,1800$ rpm$.$

Bob says that the new motor will rotate at a slower speed that the old motor, filling the vat faster, so the motor$-$on time in the PLC needs to be increased.

Doug says that the new motor will draw more current, so they should check that the circuit breaker and wiring are suitable.
