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).
