A drill motor is started in the clockwise direction with S1. After 3s, the feed is activated.
When the depth limit at I0.3 is reached, the feed is deactivated. A spring returns the drill to
the initial position. In doing so, the drive turns counter-clockwise (Q0.0 and Q0.1 are "1").
When the initial position I0.4 = "1" is reached, the drive continues to operate for 1s until the
drill is fully switched off. The drill can always be switched off with Stop (activation with I0.0 =
"0").
