Function
The limit position control moves the motor depending on the two limit switch signals:
● When a limit position is reached, the inverter stops the motor.
● At a limit position, the inverter starts the motor with a new motion command in the
direction of the opposite limit position.
● If neither of the limit positions has been reached when the power is switched on, the
polarity of the speed setpoint decides in which direction the motor is to start with the first
motion command.
The function is described in the following example.
Roller conveyor with rotary table
Application
230
A rotary table in a roller conveyor directs
the material at the crossing of two con-
veyor lines. The rotary table rotates
through 90° from one limit position to
the other. Two limit switches signal the
respective limit position. The signal to
start the rotary table comes from the
higher-level controller.
