Verifying the Direction of Movement

Definition of Direction of Movement

In the case of a rotary motors, direction of movement is defined in accordance with IEC 61800-7-204: Positive direction is when the motor shaft rotates clockwise as you look at the end of the protruding motor shaft.

It is important to maintain the IEC 61800-7-204 directional standard within your application because many motion-related function blocks, programming conventions, and, safety-related and conventional devices expect this underlying assumption within their logic and operational methodologies.

If your application requires an inversion of the direction of movement, you can parameterize the direction of movement.

The direction of movement can be verified by starting a movement.

Verifying the Direction of Movement

Power supply has been powered on.

• Start the operating mode Jog. (HMI: (op) → (JOg) → (JGST))

  The HMI displays (JG-).

Movement in positive direction:

• Press the navigation button and hold it down.

  A movement is made in positive direction.

Movement in negative direction:

• Turn the navigation button until the HMI displays (-JG).

• Press the navigation button and hold it down.

  A movement is made in negative direction.

Changing the Direction of Movement

You can invert the direction of movement.

• Inversion of direction of movement is off:

  Movements are made in positive direction with positive target values.

• Inversion of direction of movement is on:

  Movements are made in positive direction with negative target values.

The parameter InvertDirOfMove allows you to invert the direction of movement.
