Siemens 420 manual Check list

3 Functions Issue 07/04

When commissioning, initially, a quick commissioning should be carried-out. The actual application should only be commissioned if the drive inverter – motor combination provides a satisfactory result.

If the drive is to be commissioned from a defined state, then the drive inverter can be reset to the initial state when it left the plant. This is done as follows:

Reset parameters to the factory setting (refer to Section 3.5.7)

Check list

The following check list is intended to help you to simply commission MICROMASTER and to guarantee a high degree of availability:

For all activities relating to ESDS measures

All of the screws must have been tightened to their specified torque.

All connectors / option modules have been correctly inserted and interlocked / screwed into place.

The DC link pre-charging must have been completed.

All of the components are grounded at the locations provided and all of the shields have been connected.

MICROMASTER has been designed for defined mechanical, climatic and electrical ambient conditions. The limit values may neither be exceeded in operation nor during transport. The following must always be carefully observed:

♦Line supply conditions

♦Level of pollutants and contaminants

♦Gases and vapors that can have a negative impact on the function of the drive inverter

♦Climatic ambient conditions

♦Storage / transport

♦Shock stressing

♦Vibration stressing

♦Ambient temperature

♦Installation altitude

In order to ensure that the drive inverter is successfully commissioned, in addition to completely carrying-out all of the installation work, it is important to note that the drive inverter may not be disconnected from the line supply while parameterizing the drive unit. If commissioning is interrupted due to a power failure, then parameters could be lost. In this case, commissioning must always be re-started (it may be necessary to restore the parameters to the factory setting (refer to Section 3.5.7).
