COMPLIANCE WITH “ CE ”STANDARDS

RX servomotors meet directive 73/23/ECC dated 19th February 1973 (amended by directive 93/
68/EEC dated 22 July 1993) and comply with standards EN 60034-1 and IEC 34-1/1994.

Compliance with these standards requires installation in accordance with our recommendations.
In addition, installation must be on a mechanical support providing good thermal conduction and
not exceeding 40° C in the vicinity of the motor flange.

Applications : All industrial applications: special-purpose machinery, material handling, packaging,

machine tools, etc.

RX servomotors may be fitted with a resolver. The signals emitted by the

RESOLVER
resolver generate speed information (role usually fulfilled by a tachometer)
and may also be used for elaborating information simulating an optical
encoder (1024 lines per revolution).

HOLDING BRAKE The brake is primarily a holding brake. Do not use for dynamic braking.
