Kinetix MMA Asynchronous Main Motors Installation Instructions
Motor Startup
For specific information on startup and commissioning, refer to the drive manual for your system. The information in this section only relates to the motors and does not
contain the full explanation on how to startup a system. For the list of drive manuals, see the
. Also see Kinetix Motion Rotary Specifications, publication
for motor data, sizing, and application information.
Inspections Before Startup
•
Manually rotate the motor shaft, check for free rotation and the lack of rough points.
•
Verify that the motor blower fan or ventilation channel is free from foreign debris.
•
Verify that the bolts, motor, or mechanical fixing screws are locked.
•
Verify the correct electrical connections and groundings on the motor and blower terminal boards.
•
Verify that the motor nameplate data is compatible with the inverter drive system.
•
Verify the correct assembly of the mechanical power transmission equipment (couplings, belts, pulleys, gears, and so on).
•
Verify the correct operation of the electric blower, the rotation indicated by the arrow, and the efficiency of the cooling system.
•
Verify any additional ground connections.
•
Verify the operation of the brake, if any, and the lack of friction when the brake is active (motor with released brake).
•
Verify that all measures and actions have been taken to avoid contact with parts under voltage or in movement.
•
Verify that all mechanical blocks have been removed.
•
Verify that no unqualified personnel can operate the system, that personnel have been notified of the startup, and that all measures to operate the motor have been
undertaken.
Maintenance and Inspection
This section goes into detail about the maintenance and inspections available for the Kinetix MMA main motors. The operations that are described in these sections must be
performed by authorized personnel and they must follow all precautions. For the implementation and operation, specific tools and devices could be necessary that are not
commonly available in all shops. If the necessary material is not available or one is not certain about how to implement the described operations, contact
with questions or concerns.
BURN HAZARD:
Outer surfaces of the motor can reach high temperatures during motor operation. Take
precautions to help prevent accidental contact with hot surfaces. Consider motor surface temperature when you
select motor connectors and cables. Failure to observe these safety procedures could result in personal injury or
damage to equipment.
WARNING:
Risk of personal injury or equipment damage. Never operate the motor with the shaft key inserted. If the
key must stay in the shaft, make sure it is appropriately secured. If there is anomalous operation or suspicion,
immediately stop the motor. The checks that are described are not sufficient for all applications or systems.
WARNING:
De-energize space heater before startup. Motor failure and damage will occur.
WARNING:
Severe damage can occur. These motors are not intended to be used with direct online operation but are
intended to be powered by three-phase inverters. Consult with
to verify the feasibility
of your application and to take the necessary precautions.
Motor data is included in Studio 5000 Logix Designer® version 34.00 and later.
Motor performance information is also available in Motion Analyzer Online for customer sizing and application configuration.
ATTENTION:
The
are not sufficient for all applications and systems. See the
additional information supplied by the system manufacturer and verify that no contradictions exist within the
system checks, startup procedures, or other installed products.
ATTENTION:
You are not permitted to disassemble the mechanical components of the motor; the exceptions are:
the blower, shaft seal, and the standard encoder replacement procedures. All other motor maintenance must be
performed by a Rockwell Automation authorized service center.
ATTENTION:
To avoid an electric shock hazard, verify that the voltage has discharged completely before
servicing.
