<1> Parameter o1-03, Digital Operator Display Selection, determines the units.
<2> The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the drive is set for
a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if the maximum applicable motor capacity is
higher than 11 kW. Refer to Power Ratings on page
<4> Set the number of motor poles to parameter E2-04 or E5-05 depending on the motor being used.
<5> Disabled when Z3-12 is set to 0 in bypass controller software versions VST800298 and later.
