Incorrect basic settings may destroy the servo positioning controller / motor and the
mechanical drive!
It has turned out to be useful to set the current limits and particularly the maximum current
of the controller to "small" values (e.g. to half of the rated current), as this prevents strain
on all components including the mechanical system if other drive parameters are
improperly configured.
To let the motor rotate in a speed-controlled manner, you have to configure the following points:
1) Activate the speed control mode (see chapter Speed-controlled mode ).
2) Set the controller enable logic to "via digital input" (see chapter Configuring the
controller enable logic ).
3) Activate the speed control via the analog input 0 (see chapter 4.2 Setpoint
assignment through setpoint selectors ) and parametrize the desired analog speed range
( chapter Analog inputs AIN0 and AIN1 ).
If you cannot use the analog input, you can also assign the setpoints via the serial interface
(see
chapter 4.2 Setpoint assignment through setpoint selectors ).
4) Before you test the controller enabling process, you should save the
parameters in the drive. To do so, click the button shown here. You can
find the button on the upper menu bar of the main window.
5) Now briefly activate the controller enabling system.
After the control system has been enabled, the shaft has to start rotating. If the motor does not show
this behaviour, there is either an error or the DUET_FL servo positioning controller has been
parameterized incorrectly. The following table shows typical errors and how you can eliminate them:
Table 7: Error elimination: Speed control
Error Remedy
The motor develops a holding
torque. It "blocks" in different
positions. The number of pairs of poles and/or the phase sequence is incorrect. Set the
correct number of pairs of poles and/or interchange the motor phases. Perform
another automatic identification. (See
chapter 3.1.1 Motor data )
The motor shaft oscillates or runs
unevenly. The parametrization of the angle encoder offset (see chapter Speed-controlled
mode ) and/or the controller parameters are incorrect. Perform another automatic
identification. (See chapter Angle encoders )
The shaft does not rotate. No intermediate circuit voltage (DC bus voltage).
The limit switches are active.
The shaft does not rotate. The actual
value window still shows a speed
setpoint of "0". The speed setpoint has not been configured correctly. Further information can be
found in
chapter 4.2 Setpoint assignment through setpoint selectors .
When you are connecting the motor phases, please have mind that the servo motor
manufacturers configure the phase sequences differently. It might be necessary to
interchange the phases U and W.
