Converter operation
• If the motor design requires connection to a specific converter type, carefully check the
supplementary data on the rating plate/supplementary plate.
• Ensure that the converter is correctly parameterized. Depending on the design, you will find
some parameterization data on the rating plate of the machine. Further information is
provided in the converter documentation. If necessary, contact the Service Center.
• Check that the supplementary equipment and devices to monitor the machine are correctly
connected and are functioning correctly.
• In continuous operation, carefully ensure that the motor cannot exceed the specified upper
speed limit n
max
or fall below the lower speed limit n
min
.
The permissible acceleration time to the limit speed n
min
depends on the parameter
assignment.
7.2.3
Insulation resistance and polarization index
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
• Before starting up a machine for the first time
• After an extended period in storage or downtime
• Within the scope of maintenance work
The following information is provided regarding the state of the winding insulation:
• Is the winding head insulation conductively contaminated?
• Has the winding insulation absorbed moisture?
As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
• Can the machine be put into operation?
• Must the windings be cleaned or dried?
Detailed information on testing and the limit values can be found here:
"Testing the insulation resistance and polarization index"
7.2.4
Testing the cooling of the machine
Cooling
• Check that the machine cooling is available for commissioning.
