commanded speed.
NOTE: An initial value for this parameter is automatically computed by the
"Spreadsheet" tool or by an auto-configuration procedure of the controller.
The initial value may turn out to be just right, or may require manual
tuning during a drive commissioning process.

Field Oriented
Control (FOC): Kp
V/A The term "Field Oriented Control (FOC)" refers to an efficient method of
controlling brushless motors. The controller uses the method, when getting
brushless motors to produce a commanded torque.
The FOC Kp parameter is a proportional gain of two similar PI controllers
that manage Iq and Id electrical currents within a brushless motor under
Field-Oriented Control (FOC). The higher the gain, the stronger the
controller responds to perturbations in the electrical currents by managing
Ud and Uq output voltages.
NOTE: The value for this parameter is automatically computed by the
"Spreadsheet" tool or by an auto-configuration procedure of the controller.

Field Oriented
Control (FOC): T
sec The FOC T parameter is an integral time constant of two similar PI
controllers that manage Iq and Id electrical currents within a brushless
motor under Field-Oriented Control (FOC).
The higher the time constant, the slower the PI controllers responds to
perturbations in the electrical currents.
NOTE: The value for this parameter is automatically computed by the
"Spreadsheet" tool or by an auto-configuration procedure of the controller.

4 Electronic Speed
Control (ESC): Kp
A/Hz Electronic Speed Control (ESC) is a function of the controller that
maintains a constant speed of the motor by automatically increasing or
decreasing torque in response to changes in speed. Note that the speed
readings are filtered by Speed Filter prior to being processed by Electronic
Speed Control (ESC) function.
The ESC Kp parameter is a proportional gain of a PI controller that
commands torque to maintain a constant speed. The parameter defines how
much electrical current needs to be driven through the motor to adjust
torque in order to compensate for a change in speed. The higher a
combined "Moment of Inertia of Rotor and Payload" is, the higher ESC Kp
parameter should be.
Tools:
• The "Spreadsheet" tool computes a correct value for this parameter,
whenever given a correct value of "Moment of Inertia of Rotor and
Payload".
