Series Brushless Controllers
GENERAL
• The BDO-Q2-40-05 controller is a 2-quadrant speed controller for electronically commutating three-phase
brushless motors with Hall sensors which are offset at 120 electrical degrees.
• The speed of the motor is set by either an internal or an external potentiometer.
• The maximum constant current can be adjusted via an on-board potentiometer.
• The direction of rotation of the motor can be preset by the Direction control input. The controller output stage
can be activated and deactivated by the Brake control input and the Disable control input.
• The controller is safeguarded against heat overload by an internal thermal cutoff.
• The controller output stage has been constructed using POWER-MOSFET technology, resulting in very high
 efciency.Withamaximumconstantcurrentof5A,themotorvoltageisreducedbyamaximum4V.

ASSEMBLY NOTE
Optimum heat dissipation is achieved by mounting the BDO-Q2-40-05 controller on a heat sink, and through the use of a thermal
conduction paste.
For longer distances between the motor and the control unit, > 12 in (30 cm), shielded cables should be used for the sensor cable
and the motor cable.

IftheBDO-Q2-40-05controllerisbroughtfromacoldenvironmentintotheoperatingenvironment,therecanbecondensation.
Wait until the controller has reached the ambient temperature of the operating environment, and is absolutely dry before it is
put into operation.

CONTROL INPUTS
Control inputs 1 (Reverse), 7(Disable) and 8 (Brake) can be enabled either by an external switch, an open collector transistor,
or by means of TTL / CMOS components. This connection is made to 2 (Gnd).
Control input Input open or high level Input on Gnd or low level
Rev Turning to the right (CCW) Turning to the left (CW)
Dis Controller active Controller inactive
*Brake Controller inactive Controller active
*Note: If the Brake input is not used, please jumper between 8 (Brake) and 2 (Gnd).
SELECTING MOTOR DIRECTION-OF-ROTATION
Reversing the direction of motor rotation is easily accomplished. Using a switch, relay contact, or simply a jumper wire, connect the
terminal labeled Rev. to the terminal labeled Gnd.
Note: Do not reverse motor direction while the motor is rotating. The controller is not designed for instantaneous reversing.
SPEED CONTROL
Motor speed may be controlled via one of the following three methods (see page 4 and 5 for detail instructions):
1. On-Board Speed Potentiometer
2. External Speed Potentiometer – (Recommend 10k – 10 Turn Precision Potentiometer)
3. External Control Voltage

The following is a procedure for using each of the speed control methods mentioned on page 3.
1. On-Board Speed Potentiometer
  A. PlaceajumperfromterminallabeledGND to terminal labeled SV.
B. Rotate the trimpot labeled Speed fully CW.
C. Rotate the trimpot labeled nmax fully CW.
  D. Applytheoperatinginputvoltageacross+ Input and Gnd, being careful to observe polarity.
Do not apply an incremental input voltage, but rather a single step voltage.
E. Motor should now be running at full speed. Measure and record speed.
F. Slowly rotate the nmax trimpot CCW until the motor speed decreases slightly, then slowly rotate the trimpot back CW until
the motor is once again running at full speed (see value recorded in step E).
  G.Thenmax trimpot is now “tuned” to the motor currently connected to the controller and will not require readjustment unless
a different motor is connected to the controller, or the level of the input voltage is changed.
H. Motor speed may now be varied by using the Speed trimpot.
2. External Speed Potentiometer (Optional)
NOTE: See Figure 1 for connection diagram for External Speed Potentiometer.
  A. RotatetheExternal Speed Potentiometer fully CCW.
B. Rotate the trimpot labeled Speed fully CCW.
C. Rotate the trimpot labeled nmax fully CW.
  D. Applytheoperatinginputvoltageacross+ Input and GND, being careful to observe polarity.
Do not apply an incremental input voltage, but rather a single step voltage.
E. Motor should now be running at full speed. Measure and record speed.
F. Slowly rotate the nmax trimpot CCW until the motor speed decreases slightly, then slowly rotate the trimpot back CW until
the motor is once again running at full speed (see value recorded in step E).
  G.Thenmax trimpot is now “tuned” to the motor currently connected to the controller and will not require readjustment unless
a different motor is connected to the controller, or the level of the input voltage is changed.
H. Motor speed may now be varied by using the External Speed Potentiometer.

3. External Voltage Control (Optional)
 ByapplyingaDCvoltagebetween3(SV)and2(Gnd),thefollowingconditionsareobserved:
  A. 0to0.5volts–speed = 0.
B. 0.5 to 5.0 volts – speed range in control operation.
C. 5.0 to 10.0 volts – no pulse-width-operation-control works in simple commutation mode.
D. On-board speed potentiometer must be set fully CCW.
Note: Some power supplies used to supply this external voltage may contain large amounts of ripple. If speed control is unstable, please
install a 10μF electrolytic capacitor across 9 (Spd) and 8 (Gnd). BE SURE TO OBSERVE POLARITY WHEN INSTALLING THIS
CAPACITOR; 9=Positive, 8=Gnd.
CURRENT LIMITING
Current limiting is available via the on-board current potentiometer. The settings are as follows:
Fully CCW – maximum setting
Fully CW – minimum setting
FUSING
Proper overcurrent protection (fusing) is required for the protection of this controller. We recommend a 5 amp – 120 volt – non-time delay
fuse. This fuse should be connected in series with the + Input line going to the controller.
Note: Considerations regarding the power supply:
Output voltage: > 12 V and < 40V with a residual voltage of < 5%
Output Current: corresponding to the necessary torque and possible reserves for acceleration
Note: Procedure for calculating the necessary minimum supply voltage:
Default: Torque MB[mNm]
Operating speed nB[min–1]
Rated voltage of the motor UN[V]
  IdlingspeedwithUNn0[min-1]
Characteristic curve slope Δn[min-1mNm]
  ΔM
Result: Vcc = *( nB+ *MB) + 4V
HOOK-UP PROCEDURE
1. Connect motor connections (φA, B, and C).
2. Connect Hall sensors (S1, S2, and S3), as well as the Hall voltage supply (Vcc and Gnd) of Hall sensors.
3. Connect the control inputs according to the requirements (Rev., Dis., and Brake).
4. Connect the supply voltage (+ input and gnd).
5. Set up the speed control for the controller (depending upon which method of speed control is used - see Speed Control).
