1.3.2. Stand Alone Demonstration Mode Operation
To start the demonstration sequence press the P4 button
The board should follow the following sequence:
 The motor should start and accelerate to a steady speed
 The motor will run at this speed and direction for approximately 10 seconds
 The motor shall then reverse direction
Decelerate =>
Stop =>
Change direction =>
Accelerate to the previous speed =>
Continue operating for a further 10 seconds =>
The motor shall then stop
The sequence can be repeated by pressing the P4 button again.
The motor speed is defined by the Minimum and maximum speed settings.
When running from the hardware the demonstration speed is defined by the default settings in the motor
control IAR project or those set during a previous session when using the GUI
The basic speed is calculated as follows:-
Demonstration Speed = Min Speed + ((Max Speed – Min Speed) / 4)
This setting of the demonstration speed equation can be changed in the code contained in the “motorcontrol.c”
source file
1.3.3. Demonstration Mode using the GUI
The YRMCKITRL78G14 demonstration can also be operated as described above using the control GUI.
To start the demonstration press the “DEMO” button in the PC GUI
The demonstration will follow the same sequence as described for the stand alone operation above.
If the GUI is installed and running, the graphs will be updated with the running data (Speed, Voltage and
Current) even if the demonstration is started from the push button on the board.
Note the “RPM SPEED” indicator does not operate in demonstration mode. The measured speed is
updated as normal. The demonstration speed should be the same if the minimum and maximum speed
settings have not been changed in the “parameter setting” window.
