Section 2

Installation & Operation

Overview	Installation should conform to the National Electrical Code as well as local codes and
	practices. When other devices are coupled to the motor, be sure to install protective
	devices to prevent accidents. Machinery that is accessible to personnel should provide
	protection in the form of guard rails, screening, warning signs etc.
Location	The motor should be installed in an area that is protected from direct sunlight, corrosives,
	harmful gases or liquids, dust, metallic particles, welding spatters and vibration.
	Exposure to these can reduce the operating life and degrade performance. Be sure to
	allow clearance for ventilation and access for cleaning, repair, service and inspections.
	Ventilation is extremely important. Be sure the area for ventilation is not obstructed.
	Obstructions limit the free passage of air. Motors get warm and the heat must be
	dissipated to prevent damage.
	These motors are not designed for atmospheric conditions that require explosion proof
	operation. They must NOT be used in the presence of flammable or combustible vapors
	or dust.
Clean Room	Stages prepared for Class 10, 100 and 10,000 clean room requirements can be ordered
	as an option to our standard products. Materials must be suitable for the specified
	environment. The customer must perform the final cleaning due to contamination during
	shipping and handling.
	The most common changes to the stages include the replacement of the bellows,
	installation of special greases, elimination of bearing shields and the removal of other
	non–critical components that may contribute to particle generation.

Mounting a Stage to the Machine Base and Payload To Stage

SYour stage is provided with mounting holes to attach the stage to a machine base. If your stage is supplied with bellows, you must remove the bellows to access the mounting holes. The mounting holes are typically non–threaded, counter–bored holes that accommodate a variety of screw sizes. It is recommended that a hardened machine screw be used. Refer to the mechanical drawings provided with your stage for mounting screw size and hole locations.

SThe flatness of your mounting surface will greatly influence the flatness and straightness specification of your stage. The stage structure will tend to mirror the flatness of the mounting surface. For the stage to maintain its specification, it must be mounted to a surface that is flat (maximum error of 0.0005 inches per foot). A maximum of 0.010 inches per foot is the maximum mounting surface flatness error allowable for operation of the stage. However, at 0.010 inches per foot mounting base flatness, the stage flatness and straightness specification will be degraded.

SThe mounting surface must be clean and free of particles that could affect flatness (particles that come between the stage and the mounting surface) . It is also recommended that the base of the stage be cleaned to remove contamination. Cleaning with alcohol or acetone is suggested, however avoid submersion or contamination of the internal components.

SWhen mounting the payload to the slide assembly, use the same precautions mentioned for the stage. Refer to the stage outline drawing for hole locations and specifications.

SWhen pinning is required, Baldor recommends that the stage be machined and assembled at the factory.

Note: It is strongly recommended that a thread locking compound be used when mounting the stage to the base and when mounting the payload to the slide assembly.
