Restrictions for the unit changeover function
● The values on the rating plate of the inverter or motor cannot be displayed as percentage
values.
● Using the unit changeover function several times (for example, percent → physical unit 1
→ physical unit 2 → percent) may lead to the original value being changed by one decimal
place as a result of rounding errors.
● If the unit is changed over into percent and the reference value is then changed, the
percentage values relate to the new reference value.
Example:
– For a reference speed of 1500 rpm, a fixed speed of 80% corresponds to a speed of
– If the reference speed is changed to 3000 rpm, then the value of 80% is kept and now

Changing over the motor standard

You change over the motor standard using p0100. The following applies:
● p0100 = 0: IEC motor (50 Hz, SI units)
● p0100 = 1: NEMA motor (60 Hz, US units)
● p0100 = 2: NEMA motor (60 Hz, SI units)
The parameters listed below are affected by the changeover.
