Converter operation
The following chapter is relevant only if the machine has been ordered for converter operation.
Note
The order number shows whether the machine was ordered for converter operation. In this
case, digits 1, 2, 3 or 4 is located at the 6th position of the order number.
Converter operation
● If the design of the motor requires connection to a particular converter type, the rating plate
will contain corresponding additional information.
● The converter is correctly parameterized. The parameterization data is specified on the
rating plate of the machine. Information about the parameters is available in the operating
instructions for the converter.
● Any supplementary motor monitoring devices and equipment have been correctly
connected and are functioning correctly.
● In continuous operation, the motor cannot exceed the specified upper speed limit n
max
or
undershoot the lower speed limit n
min
.
The permissible acceleration time to the limit speed n
min
depends on the parameter
assignment.
WARNING
Dangerous voltage via the converter
As long as the feeding converter is switched on, or the DC link of the converter is not
discharged, there can be a voltage at the motor terminals even when the rotor is not moving.
The voltage is up to 1000 V, depending on the converter type.
Ensure that the five safety rules (Page 15) are followed before working on the motor.
7.3
Measuring the insulation resistance before commissioning
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?
