What are the drive differences between an ABB ACS Drives, model: ACSxxx-01E/03E/01 and ACSxxx-01U/03U/U1

Answer: The ABB ACSxxx-01E/03E/01 drive’s motor information parameters default to the following MOTOR NOM FREQ to “50Hz”, MOTOR NOM POWER is in “Kw”, REF1 MAX to “50Hz”, MAXIMUM SPEED to “1500RPM” and MAXIMUM FREQ to “50Hz”. The EMC metal screw is installed activating the EMC filter. 50 Hertz default output and power ratings in Kilowatt are standard for drives and other industrial electrical equipment in Western Europe, the United Kingdom and most countries located outside the United States of America. This is because electric motors are sized in Kilowatt ratings outside the USA; and, electric motors manufactured outside the USA run at full load speed when operating at 50 hertz.

The ACSxxx-01U/03U/U1 drive’s motor information parameters default to the following MOTOR NOM FREQ to “60Hz”, MOTOR NOM POWER is in “Hp”, REF1 MAX to “60Hz”, MAXIMUM SPEED to “1800RPM” and MAXIMUM FREQ to “60Hz”. The EMC plastic screw is installed deactivating the EMC filter, but the drive ships with the metal screw to activate the EMC filter. 60 Hertz default output and power ratings in Horsepower are standard for drives and other industrial electrical equipment in the United States of America. This is because electric motors are sized in horsepower ratings in the USA; and, electric motors manufactured in the USA run at full load speed when operating at 60 hertz.
