The speed controller is already perfectly adjusted to the motor ex
works. For this reason, we recommend that the ex-works program-
ming not be changed. Programming takes place via sound signals
generated by brief triggering of the motor rather than a speaker.
a) Setting Options of the Speed Controller
Note on function #1, driving mode
This is where you determine driving mode. Forward = forward driving only;
forward/reverse = forward and reverse driving possible. Switching from for-
wardstoreversedrivingdoesnothappenatonce,butwithabreakrmly
speciedinthespeedcontroller,toprotectthemotorordrivetrainandthe
battery.
However, when switching from reverse to forward driving, the rotating direc-
tion of the motor is switched immediately. This control type is not recom-
mended, since the motor or drive train is not protected and the strain on the
rechargeable batteries is increased as well.
Therefore, do not start forward driving immediately after reversing, but after a
shortbreak(brieyleavethethrottleleverintheneutralposition).
Note on function #2, number of battery cells
Use this to specify whether the cell number of the rechargeable battery is to
be recognised automatically, or selected manually.
If you use NiCd or NiMH batteries for operation of the model, programme
thespeedcontrollerto"Automatic".Initialisationofthespeedcontroller(if
connecting the driving battery) emits a control sound for the selected setting.
If using a LiPo drive battery, you can also chose the setting "Automatic". In
this case, the speed controller automatically recognises the number of LiPo
cells of the drive battery.
However, this poses the danger that batteries not charged completely are
recognised incorrectly. In this case, the speed controller would recognise a
rechargeable battery, e.g. with fewer cells. This leads to incorrect values for
undervoltage recognition and the connected rechargeable battery could be
deep discharged and therefore destroyed.
Therefore, we recommend programming the actual number of cells when
using LiPo batteries. If you choose, e.g., a LiPo battery with six cells, six
