Flowchart

Remark concerning current measurements:
1.) In order to measure correctly, the controller must run at full throttle at least 4 s in the course of the whole
flight.
In case of constant rpm setting (Heli const. RPM) this condition may not be fulfilled and the measurement will
not correspond to real values.
2.) The real average current may travel between the measured value of maximum and minimum current.
According to flying style it may approach one or the other value.

18 Flowchart
The controller registers the overall motor run time.
The controller measures the overall time from the first switch-on of the switch (activation of the
controller) until switch-off of the controller. The time is measured from the first motor revolution.
Set the number of motor poles by means of the push-buttons L-R . This parameter is important
for correct readings of the max. rpm.
Set the gear ratio of the gearbox. Apply 1:1,0 for direct drive
In the course of operation the controller registers the max. motor rpm and the time at which
these rpm have been achieved.
The controller registers the max. rpm of the propeller in the course of operation and the time at
which these rpm have been achieved.
If parameters have been exceeded – voltage (U), temperatures (T), commutation (C) and
current (I), protections will be activated and the motor will be cut-off. The reading y means that
parameters became exceeded (an error occurred), the reading n indicates that parameters
have not been exceeded. With the help of this error notification the cause of motor cut-off can
be determined.
Remark. Protection in case of incorrect commutation (C) – if operation becomes unsafe due
to many commutation errors as a result of incorrect motor design. In some cases this problem
can be solved by increasing the motor timing.
