6-4 Drive Control MPH-02, MPB-02, MPD-02
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
Open-loop U/f motor control is characterized by the following features or
core functions:
monitoring and limitation of the maximum stator frequency change
that results from the command velocity change
stall protection loop (PI loop that can be optionally activated to
prevent breakdown of the machine when the torque limits are attained)
slip compensation (feedforward of estimated slip of the machine by
means of slip compensation factor)
calculation of output voltage by means of a U/f characteristic based
on motor model data
subsequent trimming of magnetization via premagnetization factor, as
well as linear or square characteristic to be selected
IxR boost (adjustable load-dependent feedforward of the output
voltage due to the voltage drop on the motor winding resistance)
oscillation damping (adjustable load-dependent feedforward to
prevent velocity oscillations in the partial load and idling ranges)
current limitation loop to protect the output stage of the drive
controller
velocity search mode of a coasting machine after switching drive
enable on (can be set for the preset rotational direction or both
rotational directions)
acceptance of the limitation of the available peak current by current
limitation loop
user-side torque/force limitation via stall protection loop
