Warning
For series commissioning, all of the communication interfaces as well as also the digital and
analog interfaces are re-initialized. This results in a brief communications failure or causes
the digital outputs to switch.
Potentially hazardous loads must be carefully secured before starting a series
commissioning.
Potentially hazardous loads can be secured as follows before starting series commissioning:
• Lower the load to the floor, or
• Clamp the load using the motor holding brake.
