Description: Closed loop: The slope of the velocity dependent current decrement rate. See also
cial settings, page 106.
8.2.110 KPHASE
Reg Name
216 KPHASE
The KPHASE parameter is decisive for how far commutation of the motor is offset from
the motor's actual position. KPHASE is velocity dependent, which means that it has in-
creasing significance as motor velocity increases. The KPHASE parameter is factory cal-
ibrated, but can be adjusted by the user if necessary.
Finding the optimal KPHASE
The optimal KPHASE value is found by running the motor at high speed (2000 RPM) and
observing the "Actual torque" in MacTalk. The actual torque will settle at its minimum
value at the optimal KPHASE. The new KPHASE can be saved in flash and will then be
used automatically after a reset.
