Limit position control

Overview
An end position is a position in the direction of motion of a machine component where motion
stops as a result of the inherent mechanical design. A limit switch is a sensor that signals that the
end position has been reached.
The end position control of the converter controls the motor depending on 2 limit switch signals:
• When an end position is reached, the converter stops the motor.
• At one end position, the converter prevents the motor from moving the machine
components further in the direction of this end position.
