Series Brushless Controllers
GENERAL
• The BDP-Q2-50-10, BDP-Q2-20-10 controllers are 2-quadrant speed controllers for electronically
commutating three-phase brushless motors with Hall sensors, which are arranged offset at 120
electrical degrees.
• The speed of the motor is preset by means of 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 means of the Direction control input.
The controller output stage can be activated and deactivated by means of the Disable control input.
• The controller is safeguarded against heat overload by means of an internal thermal cutoff.
• The controller output stage has been constructed using POWER-MOSFET technology, resulting in very
 highefciency.

ASSEMBLY NOTE
Optimum heat dissipation is achieved by mounting the BDP-Q2-50-10, BDP-Q2-20-10 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.
SAFETY NOTE
Operatingvoltagesexceedingthespeciedvalues,orreverseconnectionwilldestroythecontrollerandwillvoidthe

Unauthorized opening and improper repairs will put the user in danger and will void the product warranty.
If the 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.

TERMINATION TABLE
Terminal # Nomenclature Description
1 GND Gnd for Supply Voltage
2 Positive Input Positive Supply Voltage
3Phase A Motor Phase A
4 Phase C Motor Phase C
5 Phase B Motor Phase B
6 S3 Hall Switch #3
7 S2 Hall Switch #2
8 S1 Hall Switch #1
9 VCC Supply for Hall Switches
10 GND Gnd for Hall Switches
11 DIS Control Input - Disable
12 REV Control Input - Reverse
13 GND Gnd for Dis and Rev
14 SPD Set Value Input for Speed
CONTROL INPUTS
Control inputs 12 (Reverse), 11 (Disable) can be enabled either by an external switch, an open collector transistor, or by means of
TTL / CMOS components. This connection is made to 13 (Gnd).
Control input Input open or high level Input on Gnd or low level
Rev Turning to the right (CW) Turning to the left (CCW)
Dis Controller active Controller inactive
*Note: For positive stopping of the motor it is advisable to use the Disable input rather than setting the speed
potentiometer to zero. Some drift may occur even at zero setting of the speed potentiometer; this will not be the case
when the Disable function is used.
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 Spd.
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 CW.
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 14 (Spd) and 13 (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. Speed potentiometer should be fully CCW.
E. Rotate the trimpot labeled nmax fully CW.
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.
CURRENT LIMITING
Type Max. Left Position Max. Right Position
BDP-Q2-50-10 0 A > 10 A
BDP-Q2-20-10 0 A > 10 A
Note: The controller shuts down automatically when the temperature at the inside of the heat sink exceeds 80°C.
FUSING
Proper overcurrent protection (fusing) is required for the protection of this controller. We recommend a 10 amp , non-time delay fuse.
This fuse should be connected in series with the + Input line going to the controller and should be of a value less than or equal to the
maximum current rating of the controller (Max. Right Position).
Note: Considerations regarding the power supply:
Output voltage: > 12 V and < + input 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]

PUTTING INTO OPERATION
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. and Dis.).
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).
6. After completion of step #5, speed control is now active.
7. Set the maximum current via the on-board speed potentiometer (current).
