[Inertia Comp Out]
Displays the output of the Inertia Compensation function. The [Inertia Comp
Out] signal (if selected by Par 1016 [SpdFuncSelect]) is summed with Pars 14
[Selected TorqRef] and 40 [Trim Torque]. Inertia compensation provides a
torque feed forward signal during changes in motor speed reference.
Note: This parameter was added for firmware version 4.001.

[Drive Size]
Armature current rating (as indicated by the configuration of DIP switch S15

Note: S15 is set to the appropriate value at the factory. However, if the control
board was supplied separate from the drive and installed as a replacement
part, S15 must be manually set to the appropriate drive size. See DIP Switch
