Technical Data - Modelcraft Pk01 Bedienungsanleitung

Setting a high timing (high degree number) means that the motor has a little higher maximum
speed as compared to the basic settings, and a little less torque. In both cases, the current values
change however. Therefore, also observe compliance with the motor and flight controller
specifications. Also observe the temperatures of the components named in operation.
If you do not have the corresponding specialist know-how and matching measuring equipment,
we recommend the setting „auto". In the setting „auto", the best setting used for the motor is
automatically set.
„5" = „SBEC Voltage Output"
In this menu item, the output voltage of the BEC for flight controllers with „SBEC" can be set to
5.0 V, 5.5 V or 6.0 V.
In flight controllers without BEC (e.g. type „Opto 120A") or regular BEC (e.g. type „BEC xxA"), this
menu item is present, but a change or programming has no effects.
„6" = „Governor mode"
a) Softstart
Programming the „Softstart 1" continually adjusts the motor speed up from 0% (depending on the
programmed value for the starting characteristics) to 100% in about 8 seconds if the transmitter
sends the control signal „Full throttle".
At „Softstart 2", this increase takes about 18 seconds.
The „Softstart" function is recommended if you want to control the motor of an electric glider by
switch on the transmitter.
If you adjust „full throttle" back to „motor off" within 3 seconds of speed increase, soft
start is off for the next motor start within 3 seconds.
If repeated start-up of the motor is more than 3 seconds before the last „motor off"
control signal the softstart is activated again.
b) Governor Mode
Programming the „Governor Mode" in your flight controller continually adjusts the motor speed
up from 0% to 80% of the maximum speed in about 23 seconds if the transmitter sends the control
signal „Full throttle". For this, you need to programme a fixed value for full throttle on the
transmitter (max. 80%).
With the Governor mode active, the speed is kept near-constant at a load change as well as
undercutting of the throttle value specified in the transmitter (throttle pre-selection/pitch curve)
under 80%.
In case of a high load change (e.g. a helicopter, the maximum pitch deflection is controlled), the
thresholds of the possible speed control are limited by the battery's current stability and the
maximum torque of the motor. If one of the two possible parameters is exceeded, the speed
control can no longer work completely either.
The function „Governor-Mode" is recommended for helicopters. „Governor-Mode 1" is designed
for motors with a low number of turns (less than 50000 turns). „Governor-Mode 2" is designed
for motors with a high number of turns (above 50000 turns).
The number of turns is calculated as follows: Number of poles from motor x KV of the motor x rated
voltage of the battery = number of turns.
Example: 8-pole motor x 1040 KV x 6-cell Lipo battery (22.2 V) = 184704 turns.
In this case, programme „Governor-Mode 2".
It is possible that the flight controller does not speed up to the speed programmed in the
transmitter in spite of correct selection of Governor mode 1 or 2 according to the flight controller's
calculation. In this case, programme and test the respective other Governor-Mode.
If the Governor-Mode is programmed, the motor brake is deactivated independently of the earlier
programming and the motor's output is controlled back when undervoltage is reached.
If you adjust „full throttle" back to „motor off" within 3 seconds of speed increase, soft start is off
for the next motor start within 3 seconds. If repeated start-up of the motor is more than 3 seconds
before the last „motor off" control signal the softstart is activated again.
„7" = „Motor Rotation"
This function changes the rotating direction of the motor without swapping the cables between
the flight controller and the motor. 1 = regular rotating direction, 2 = reversed rotating direction.
„8" = „Start Up Strength"
Here you can set the starting characteristics when moving the transmitter's control lever from
„motor off" towards „full throttle".
The higher the value set, the stronger the motor's initial torque. The following values are
available: 1 = 10%; 2 = 15%; 3 = 20%; 4 = 25%; 5 = 30%; 6 = 35%; 7 = 40%; 8 = 45%; 9 = 50%.
The values 10% - 20% correspond to a soft start-up, the values 25% to 35% correspond to a
harder start-up and the values 40% to 50% to a hard start-up.
„9" = „Low Voltage Cut Off Type"
Select how the flight controller is to react if undervoltage recognition is activated (see menu item
„3").
Select „reduction" to reduce motor power when the undervoltage limit is reached. Select
„deactivation" to deactivate the motor completely when the undervoltage limit is reached.
