: Field Weakening Maximum Velocity
Maximum speed for field weakening operation. For higher velocities the influence of the back EMF may be
compensated. At the field weakening minimum velocity (section 4.2.32) plus this velocity the back EMF
compensation will reach its maximum.

: Boost Current
This object defines the motor current that will be used during the acceleration phase and the deceleration
phase in open-loop mode. A value of 255 means 100% of the maximum motor current of the drive.
When this object is set to zero the run current (section 4.2.4) will also be used for the acceleration abd
deceleration phase.
