6.2      Unidrive M100/101 parameter descriptions
Key:
Set Pr 00.001 at the required minimum output frequency of the drive for both directions of rotation. 
The drive speed reference is scaled between Pr 00.001 and Pr 00.002. Pr 00.001 is a nominal value; 
slip compensation may cause the actual frequency to be higher. When the drive is jogging, Pr 00.001 
has no effect.
Set Pr 00.002 at the required maximum output frequency for both directions of rotation. The drive 
speed reference is scaled between Pr 00.001 and Pr 00.002. Pr 00.002 is a nominal value; slip 
compensation may cause the actual frequency to be higher. The drive has additional over-speed 
protection.
Set Pr 00.003 at the required rate of acceleration. Note that larger values produce lower 
acceleration. The rate applies in both directions of rotation.
Set Pr 00.004 at the required rate of deceleration. Note that larger values produce lower 
deceleration. The rate applies in both directions of rotation.
