Example
After it has been switched on, a conveyor belt only runs with two different velocities. The motor
should now operate with the following corresponding speeds:
• The signal at digital input 0 switches the motor on and accelerates it up to 300 rpm.
• The signal at digital input 1 accelerates the motor up to 2000 rpm.
• With signals at both digital inputs, the motor accelerates up to 2300 rpm.
