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 output 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

(Caution: During series commissioning, MICROMASTER must be prevented from controlling the motor holding brake).

If the motor holding brake (refer to Section 3.13) is controlled by the MICROMASTER, then series commissioning may not be carried-out for potentially hazardous loads (e.g. suspended loads for crane applications).
