SERVO DRIVES & MOTION CONTROL BF/400 VAC RACK CINFRANOR BF RACK /400 VAC

This is a general manual describing a series of racks receiving servo amplifiers having output capability for driving AC brushless servo motors. This manual may be used in conjunction with appropriate and referenced drawings pertaining to the various specific models. Maintenance procedures should be attempted only by highly skilled technicians (EN 60 204.1 standard) using proper test equipment. The conformity with the standards and the "CE" approval are only valid if the items are installed according to the recommendations of the racks and amplifiers manuals. The user will be responsible for...

1 - CONFORMITY WITH THE EUROPEAN STANDARDS: "CE" APPROVAL The 400 V rack type of the "B" series is "BF/400". The "F" means "floating" power bus voltage, because it is not referenced to the chassis. This range is ALWAYS equipped for rear mounting. The motor outputs and the supply inputs are ALWAYS on a terminal bar. The logic inputs - outputs of the X5 rear connector allow the serial connection of the protection signals AMP. READY and POWER READY. All connections are ALWAYS made on the top of the rack (power supply, motors, logics). The "BF/400" rack is to be directly connected to the 400 VAC...

1.2 – Reference to the standards The SMT-BD1/400/I amplifiers mounted into the BF rack in 400 VAC, which is equipped with the mains filter F-400-70, have been approved for their conformity with the EMC standards: • • EN 55011, Group 1, Class A, regarding radioelectric disturbances CEI 801 - 2 - 3 - 4, regarding the immunity. The tests have been performed by the external laboratory of the SCHAFFNER company, which is approved for its competence regarding EMC. The results of the tests made according to the Low Voltage directive are referenced in the LCIE report n° 413777. Standard for the electrical...

CINFRANOR DEFINITION OF THE BACKPANEL X5 CONNECTOR The X5 connector allows to have: - the logic ENABLE signal common to all axes, - the POWER READY relay serially wired on all axes, - the AMP. READY relay serially wired on all axes, - the Idyn relay serially wired on all axes. SPECIFICATIONS : Umax : 50 V Imax = 100 mA Pnom = 5 W On some INFRANOR amplifier types, the Idyn relay may have another function, particularly the control of the motor brake relay on the ranges BD1/m, BD1/h, BD1/p and BD1/s. In this case, the Idyn relay must be independent on the rack backpanel (switches O and P = OFF)....
