Receiving
Each ABB Motor is thoroughly tested at the factory and carefully packaged for
shipment. When you receive your motor, there are several things you should do
immediately.
1. Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered your motor.
2. Verify that the part number of the motor you received is the same as the part
number listed on your purchase order.
Storage
If the motor is not put into service immediately, the motor must be stored in a clean,
dry and warm location. If the parts are not put into service immediately, store them
in a clean, dry and warm location. The motor must be protected from moisture and
condensation. Storage area should be a dust free environment, maintained −25 degC
to +85 degC and less than 90% relative humidity non−condensing.
Unpacking
Each ABB motor is packaged for ease of handling and to prevent entry of contaminants.
1. To avoid condensation inside the motor, do not unpack until the motor has
reached room temperature. (Room temperature is the temperature of the room
in which it will be installed). The packing provides insulation from temperature
changes during transportation.
2. When the motor has reached room temperature, remove all protective wrapping
material from the motor.
Handling
Use proper care and procedures that are safe during handling, lifting, installing,
operating and maintenance operations. Improper methods may cause muscle strain
or other harm.
Repairs
ABB will not share any responsibility for damage caused by customer attempt to
repair or modify a motor. Consult ABB for any service.
Prevent Electrical Noise
Electro-Magnetic-Interference (EMI), commonly called "electrical noise" may adversely
affect motor performance by introducing stray signals. Effective techniques to reduce
or prevent EMI include AC power filters, cable shielding, separating signal wires from
power wires and good grounding techniques.
Effective AC power filtering can be achieved by using properly installed "Isolated AC
Power Transformers" or "AC Line Filters". Other techniques are:
•
Install motor cables and signal wires in separate conduits.
•
Do not route motor cables and signal wires in parallel. Separate cables by at
least 1 foot for every 30 feet of run.
•
Cross signal and power wires at 90 degree angles to prevent inductive noise
coupling.
•
Do not route signal wires over the vent openings of the servo drives.
•
Ground all equipment using a single point ground system.
•
Keep wires as short as possible.
•
Ground both ends of the encoder cable and use twisted pair wires.
•
Use shielded motor cables to prevent EMI from other equipment.
