2. Introduction
Motor Controller is used to control the Dynamic Mixer DM50 or other BLDC motors. Motor Controller is intended for
industrial use only and is not approved for use in explosive area.
Installing the Motor Controller MP72
The Motor Controller MP72 should be installed where
it is protected from dust and water. It is made to be
attached to a DIN-rail, to which it snaps easily and
can be removed by pushing up and bending the top
out. The connector terminals 1-7 and 8-17 can be
removed by pulling the connector out. Profibus is
connected to the Profibus DP (D-sub) connector, see
chapter 8: Connecting Profibus.
The Motor Controller MP72 should be installed in
accordance with national regulations. A person with
the required knowledge should perform the
installation.
MP72 should be connected to a 24V power supply
with sufficient power output.
Minus of the power supply (24V MINUS) should be
connected to the system ground if possible. Voltage
on the power inputs should not exceed 35V relative
ground.
The cable between Motor Controller MP72 and the
motor must be shielded.
Motor Controller MP72 contains an inverter controlling
the speed of the motor. The motor winding and hall
sensors must be connected correctly in order for the
motor to function correctly. If wrongly connected the
motor will draw high current, vibrate or not run at all.
The wires to hall sensors A, B and C are sensitive to
radiation and should not be adjacent to any of the
three cables connected to the motor windings within
the cable.

Installing the Motor Controller MP128
The Ultrasound Controller MP128 is protected according to IP65 and can be installed outside a protecting cabinet. The
bottom plate must be removed (8 screws) in order to access the terminals to connect the cables. Remove dummy
coverings and insert cable glands as many as needed. There are 3 small and 4 big cable glands, see page 6. There
should be only one cable in each cable gland to achieve IP65 protection. The pressure compensation element can be
moved but must not be removed. Make sure the gasket is in place when screwing the bottom plate.
The Motor Controller should be installed in accordance with national regulations. A person with the required knowledge
should perform the installation.

3. Using the Motor Controller
Keep MENU pressed to scroll continuous through parameter values. Press BACK while pressing MENU to scroll
backwards.
Start-screen
As soon as the power is applied to the Motor Controller, it starts displaying the
program revision on the LCD-display, quickly followed by the start-screen. The
start-screen shows MP72/MP128 on the first line and on the second line
it shows to the left:
200 setrpm The set speed is 200 rpm.
227 rpm Motor is running with the speed of 227 rpm
Not Calibrated Calibration must be done.
Cal Error Error has been detected during calibration. Calibration must be done again.
Error x Error. X is the error number, see troubleshooting.
xxx If profibus communication is enabled there is a Profibus status-symbol here. If 4-20mA
communication is selected it says 4-20mA here.
MIXER Run-Stop
In “MIXER Run-Stop” menu the mixer motor can be started and stopped. At power off “MIXER Run-Stop” will be reset
to Stop. If Profibus is enabled it will take control.
MIXER SPEED
In “MIXER SPEED”menu the Mixer SetSpeed can be set. But if Profibus is enabled it will take control. Maximum
speed is 1000rpm. (Profibus parameter Maximum Speed is ignored). Lowest speed is 25rpm. If speed is set lower than
25rpm motor will stop.
SHOW DATA
In the SHOW DATA-menu various measured data can be seen: Power supply voltage, Motor voltage, Motor Current
and Hall sensors.
Select “ErrorCode” To show Error Codes: 01= overcurrent due to short circuit. 02= Motor is stuck. 03= Calibration
error 04= Hall element error during calibration 05= Hall element error 06= Power supply voltage is lower than 18V.
SETTINGS
Trough the SETTINGS-menu the parameters of the Motor Controller can be set.
Select “CALIBRATION”: to calibrate the motor. Calibration minimizes motor power consumption and improve smooth
rotation. The Motor Controller is shipped uncalibrated and calibration must be done before use. Also if the motor or
Motor Controller has been replaced, calibration must be done again.
IMPORTANT: Calibration must be done with the motor free running and completely unloaded. The mixer must be
removed from container and the stirrer must be pulled out. Only then calibration can be done successfully. During
calibration the motor rotates slowly ½ rotation.
Select “COMMUNICATION”: to set it to DISABLE (all communication only via menu), PROFIBUS (enables
communication via Profibus), or 4-20mA (Speed via 4-20mA, Run/Stop via Run and Stop input or via menu)
Select “PROFIBUS ADDRESS”: to set the profibus address (0-126). It must be a unique address.
Select “RESTORE settings”: to restore all settings and calibrations to factory default value.

4. COMMUNICATION = 4–20mA
The value of setrpm is controlled by the current on the 4–20mA input.
The 4-20mA input (terminal 6) measures current to ground (terminal 7) via a 100 ohm resistor.
At 4mA setrpm is 0 rpm
At 20mA setrpm is 1000 rpm.
The digital inputs are terminal 3 (Run), terminal 4 (not used) and terminal 5 (Stop).
The digital inputs has an internal connection to 3,3V via a 1 kΩresistor.
Digital inputs are activated by connecting them to ground (terminal 7) via a relay, switch or transistor.
In the table High means free input, or input voltage >3V (max 6V)
Low means connected to 0V or input voltage < 0,5V (min -0,5V)
X means it is either High or Low.
Pulse is a low pulse min 20ms.

5. COMMUNICATION = PROFIBUS
The Motor Controller supports Profibus DP-V0 with communication speeds up to 12 Mbit/s.
Connecting Profibus
The Profibus cable connects to MP72 via a Profibus 9-pin D-sub connector see table page 5.
The Profibus cable connects to MP128 via terminals see table page 6.
If the Profibus cable is to be terminated in the MP128:
Put 390Ωbetween terminal 8 and 10.
Put 390Ω between terminal 7 and 9.
Put 220Ωbetween terminal 7 and 10.
The Profibus-interface in Motor Controller is not isolated from power.
The gsd-file: MP720B0E.gsd is needed for configuration of the Profibus master. It can be downloaded at
www.aqmtech.se The version of the gsd-file is written in the beginning of the gsd-file (the gsd-file can be viewed with a
text editor). It must be the correct version. See page 2 for correct version.
PROFIBUS Parameters
See SETTINGS.
Profibus Status-symbol
The current status of the Profibus communication is shown with a Profibus status-symbol on the start screen at the
bottom right corner of the display:
Blank = Profibus is not enabled.
□= Bitrate has not been detected.
█= Profibus communication has been detected and bitrate has been set.
P = Parameter or configuration telegram has been received.
e = Parameter or configuration telegram error.
> < = (alternating) Data exchange telegrams are received and responded to.
X = Ready for data exchange but no telegram is received.
C = Has been ready for data exchange but is not ready anymore.
Request Data and Response Data
The master sends 3 byte Request Data to Motor Controller which responds with 6 bytes Response Data (1-6).
See table.
When Profibus is enabled SetSpeed is controlled by Profibus. By disabling Profibus, SetSpeed can be controlled via
the menu.

TROUBLESHOOTING
Not Calibrated is shown on start-screen if the motor has not been calibrated. Calibration should be performed.
Error messages are shown both on start-screen and in SHOW DATA.
Error 1 Overcurrent protection. Motor Controller detected too high current. Possible reason: short circuit.
Error 2 Motor does not rotate although it should. Possible reason: Bad connection, too high rotation-resistance.
Error 3 Motor does not rotate as it should during calibration.
Error 4 Motor hall sensor error during calibration
Error 5 Motor hall sensor error. Possible reason: Bad connection or faulty hall sensor or faulty Motor Controller.
Error 6 Power supply voltage has been below 17V for more than one second. The motor stopped if it was running.
Possible reason: Power supply fault.
To reset the error messages (1-6), either power off Motor Controller, or start and stop the motor.
Calibration error: Possible reason: Too high rotation-resistance. Wrong order of hall sensors. Hall sensor not
connected. Hall sensor failure. If the motor does not rotate at all during calibration (1/2 rotation), possible reason is bad
connection or faulty motor or faulty Motor Controller. Calibration error message will be reset by performing a new
calibration.
Profibus status-symbol
“SETTINGS ♦COMMUNICATION” must be set to Profibus to show the profibus status-symbol.
If the Profibus status-symbol shows □all the time: Motor Controller detects no communication. Profibus cable is not
connected or has wrong polarity.
If the Profibus status-symbol shows █all the time: Motor Controller detects communication but the address could be
wrong.
If the Profibus status-symbol shows Pand erepeatedly it means the profibus master sends parameter or configuration
but MP72 thinks they are wrong so the profibus master sends them again.
If the Profibus status-symbol shows Cit means Motor Controller has once been ready for data but is not ready
anymore. A reason can be communication error or wrong number of bytes in request data.
If the Profibus status-symbol shows Xit is ready for data but it receives no data.
Error bits in Profibus Response Data 1
bit0: 1= Motor should rotate but it does not. Possible reason: see Error 2 above.
bit1: 1= ActualSpeed is not within SetSpeed ± 25%. Possible reason: load is too heavy. Reduce speed.
bit3: 1= Motor hall sensor error. Possible reason: see Error 5 above.
bit4: 1= Motor current has been limited. Possible reason: load is too heavy.
bit5: 1= Calibration has not been done or has been done with error. Calibration should be performed.
