Check The Electrical Connections; Converter Operation - Siemens SIMOTICS DP Operating Instructions Manual

• Rotate the rotor to ensure that it does not touch the stator.
• Ensure that the bearing insulation is not bridged/jumpered.
• Using the appropriately designed and adjusted control and speed monitoring functions,
ensure that the permissible speeds specified on the rating plate cannot be exceeded.
• Ensure that any supplementary equipment used to monitor the motor is correctly connected
and is functioning.
7.1.2.1

Check the electrical connections

Electrical connection
• Carefully check the grounding and potential bonding connections.
• Connect the machine corresponding to the specified direction of rotation.
• Using the appropriate open-loop control and speed monitoring functions, carefully ensure
that no higher speeds can be achieved than are permitted and specified in the technical data.
For this purpose, compare the data on the rating plate or, if necessary, the system-specific
documentation.
• Comply with the minimum insulation resistances.
• Comply with the minimum air clearances.
• Correctly connect possibly available machine monitoring devices and equipment - and
carefully ensure that they are functioning correctly.
• Check the correct functioning of the brakes or backstops.
• Set the values for "Alarm" and "Shutdown" at the monitoring devices.
• Carefully ensure that temperature-sensitive parts and components, e.g. cables are not in
contact with the machine enclosure.
7.1.3

Converter operation

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
The permissible acceleration time to the limit speed n
assignment.
