Some of the parameters are product code dependent, that is, they are different for each
frame size and power rating. For example, the unit will be set for either 50Hz or 60Hz
operation:
Motor Poles for 60Hz 2 poles = 3600 rpm, 4 poles = 1800 rpm, 6 poles = 1200 rpm
Motor Poles for 50Hz 2 poles = 3000 rpm, 4 poles = 1500 rpm, 6 poles = 1000 rpm
