Rated Slip Freq

Displays the control slip frequency, determined from

Par 3

[Motor NP Hertz] and

Par 4

[Motor NP RPM]. Measured and updated by the autotune procedure. Do not change this
value.
Note: Changed the attributes to allow changing this parameter while the drive is running
for firmware version 3.01.
