Shoplink

Single BL-Ctrl V3.0 2XL

power

  • voltage : 10 to 30V -> 3 -7S Lipo

  • 6 -layer PCB for optimal heat dissipation . 70u copper layers make the entire circuit board to the heat sink .
  • current: up to 60A (Peak per BL-Unit)
  • current limiting and temperature limiting
  • Active freewheeling -> less power loss

Fast response with speed control

  • rapid acceleration and braking of the propeller. Active and seamless braking gives the speed precisely and quickly on the new setpoint .
  • return energy to the lipo when braking. Seamless transition from acceleration to braking
  • significantly faster control with speed control

Other Features

  • Adjustable motor timing in several steps of 13-28° - compatible with the most common BL motors
  • Adjustable switching frequency ( 10kHz - 20kHz )
  • PPM to 500 Hz with simultaneous I2C - bus operation for telemetry and data logging
  • Software adjustable direction of rotation
  • Adjustable current and temperature limits
  • Adjustable start-PWM
  • Silent Start: test tone at startup can be disabled

Interface

  • {i} I2C-Bus with integrated opocoupler allows you to put the BL-Ctrl to the end of the rigger

  • various interfaces for setpoint input ( I2C, PPM ( 500Hz ) , serial)
  • Integrated current measurement measurement of the actual current and the used capacity on the Mikrokopter control
  • voltage and temperature measurement with data transmission to the ground station and data logging
  • 11-bit resolution (2048 steps )
  • various feedback to the MikroKopter-FlightCtrl ( blocked motor , power limiting , etc. )

  • extented configuration options (eg current limit , temperature limit , ...)
  • two LEDs per BL-Ctrl (OK and Error )
  • all BLCs are already adressed (address 1-8)
  • I2C bus access possible in PPM mode - for data logging and telemetry in PPM mode
  • status messages are transmitted to the FC ( engine blocks , Current, Self-test error ...)
  • current measurement up to 75A per controller
  • Convenient configuration of the BL controller via FC

Connection

  • Motor
    • => A, B, C

  • Adressierung
    • => by solder Jumper BL-Ctrl (see below)

  • Elko
    • => connect two capacitors 2x Elko 470µF/35V (Low-Impedance)

  • LiPo-Connection

    • => LiPo plus / minus

  • I2C
    • => Connect by 3-lines Molex cable or by soldering a 3-lines (!) cable

      => do not connect the GND-Line directly to the Minus-line of the BL-Ctrls -> go with the three lines (C, D and GND) to the FC and connect the GND there

      => the easiest way to connect the I2C-Bus is to use the Molex (See also en/Mini8)

  • PPM (Alternative)
    • => PPM = orange / + = rot / - = braun => up to 500Hz

INFO
The adresses can be set in the range beween 1 and 8. If you need adresses 9-12, please contact the shop

Settings

IMPORTANT: To change the Settings of the BL-Ctrl V3.0 you need a Software version since V2.02a (KopterTool, FlightCtrl, NaviCtrl)!

Normally you have not to change the settings! If you have to to it you can do it like described:

  • open KopterTool

  • press button "Strg" on your keyboard and hold it down.
  • Then "click" "Settings" in the KopterTool.

Now you will see the window of the BL-Ctrl V3.0.
INFO: only if you "click" and activate the single settings there you can change them.

Error codes

The BL V3 performs a selftest during startup (test-tone). In case of an error, these are the blink codes:

  • 1 "1" = Shortcut between A+ and B-
  • 2 "2" = Shortcut between B+ and C-
  • 3 "3" = Shortcut between C+ and A-
  • 4 "E" = A doesn't go to high
  • 5 "F" = B doesn't go to high
  • 6 "G" = B doesn't go to high
  • 7 "H" = A doesn't go to low
  • 8 "I" = B doesn't go to low
  • 9 "J" = C doesn't go to low
  • 10 "K" = Overcurrent when switching to low
  • 11 "L" = Overcurrent when switching to high
  • 12 "Q" = Cross-circuit between low and high
  • 15 overcurrent while starting the motor
  • 16 error current measurement
  • 17 error voltage measurement
  • 18 error temperaturen measurement

FAQ

Motor connection

The motors can be connected either on the top-side or on the bottom-side. You can ignore the small (pre-)soldered points on the top-side.
