Switch Motor
Motors can be switched Forward (Fwd), Reverse (Rev) or Off.
The speed of a motor can be specified between 10% and 100% (in steps of 10%).
•
Click on the Rev, Off or Fwd button in the row of the relevant motor.
•
The speed of the motor will automatically default to 100%. Click on the arrow button and select the
appropriate speed from the drop-down list.
In addition to motor output letters you may also be offered names – these are set by the SCE that is
currently connected.
If the program is set to Level 2 variables can be used in this command e.g. to control the speed of a
motor, Switch Motor A Fwd x).
Note: Variables for controlling motor speed are not suitable for download to the K’NEX Interface.
