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.

UNINTENDED MOVEMENT CAUSED BY INTERCHANGED MOTOR PHASES |
|
Do not interchange the motor phases. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
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.
oStart the operating mode Jog. (HMI: (op) → (JOg) → (JGST))
The HMI displays (JG-).
Movement in positive direction:
oPress the navigation button and hold it down.
A movement is made in positive direction.
Movement in negative direction:
oTurn the navigation button until the HMI displays (-JG).
oPress 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.
oInversion of direction of movement is off:
Movements are made in positive direction with positive target values.
oInversion 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.
