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.
