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.

Any contact with electrical parts, even after power down, may involve physical damage.

Wait for 30 seconds after power down before handling the rack or the amplifiers (residual voltage).

Chapter 1 – General description

1 – COMPLIANCE WITH THE EUROPEAN STANDARDS: "CE" CERTIFICATION

1.1 – General description

The rack type of the "B" series is "BF". 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 connector on the rack backpanel allow the serial connection of the AMP.

READY and POWER READY signals.

All connections are ALWAYS made on the top of the rack (power supply, motors, logics).

The "BF" rack is operating with a 380 V / 220 V (400 V / 230 V) autotransformer . But it can, of course, also work

with an insulation transformer.

The whole "B" range (SMT-BSi and SMT-BD1) is particularly well suited for the "BF" rack.

But the "BF" rack is not compatible with the bipolar amplifiers of the "B" series.

The axis width of the "B" series amplifiers (12 TE, 18 TE or 24 TE) is depending on their current ratings.

The power supply unit ALWAYS includes the auxiliary supply, the power supply and the braking system. It is

mounted on a chassis fixed on the left rack flange. Its width is 12 TE.

The braking system is equipped with a safety function indicating its correct operation. This function is called "D/R

OK" (braking system OK). It controls a relay that can be serially used with the "∑ POWER READY" signal of the

X5 connector (pins 3 and 4) in order to interrupt the power contactor in case of incorrect operation.

The power supply can be equipped with a 35 A, 70 A or 90 A rectifier bridge.

The braking system includes all options of the "B" series: D, E, D2 and D1.

Option D Option D2 Option E Option D1

Resistor 15 Ω 10 Ω 2 x 15 Ω parallel mounted 2 x option E

Rated power 140 W 280 W 560 W 1 120 W

Peak power 10 KW 16 KW 21 KW 42 KW

On both options "D" and "D2", the resistor is included in the power supply unit or mounted on the left rack flange,

whereas it is external on options "E" and "D1".

The braking resistor is under high voltage (400 V) and may become very hot. It is recommended to mountit at a correctly cooled place or outside the cabinet. But the "D2" or "E" resistors housing must in anycase be placed at least 30 cm away from any element that may burst into flame because of the brakingresistor heat radiation.

8 Chapter 1 – General description

BF RACK

The "BF" rack answers the requirements of the EN 55011 standard regarding the electromagneticcompatibility , with optional input filter for the mains rejection.

But the common mode filter of the motor output as well as the mains filter of the auxiliary supply are integrated

in the rack, as standard .

The fan must always be mounted on the top of the rack. The various fan types are depending on the amplifier

continuous current.

1.2 - Reference to the standards

The "B" series amplifiers mounted into the BF rack , which is equipped with the mains filter BF 35/70, have been

approved for their conformity with the Electromagnetic Compatibility standards:

EN 55011, group 1, Class A, regarding conducted and radiated radioelectric disturbances

CEI 801-2-3-4 regarding immunity.

The test results and conditions of the LCIE laboratory (Laboratoire Central des Industries Electriques), which is

approved by the European Community, are referenced under n° 416040 - 416041 - 416042 - 416043.

The results of the tests made according to the Low Voltage directive are referenced in the LCIE report

n° 413777.

Standard for the electrical equipments of industrial machines: EN 60204.1.

1.3 – CE marding

The racks have been CE marked since 1995.

6 – THREE-PHASE CONNECTION VIA A 380V/220V (400V/230V) AUTOTRANSFORMER

The 380 V / 400 V three-phase power supply requires the use of a 380 V / 220 V autotransformer.

The 230 Vac phase/neutral connection is possible for the auxiliary supply.

The auxiliary supply can be connected between two 220 V phases to the autotransformer OUTPUT

The auxiliary supply is connected to the autotransformer output and the power contactor is put after the auxiliary

supply connection (see connection diagram).

NOTES

With a three-phase connection, all supply lines must ABSOLUTELY be cut off to ALL POLES.

The connection via an autotransformer is the most cost effective one but it is always possible to use a 380 V /

220V (400V / 230V) insulation transformer instead of an autotransformer (same connection as shown above, with

a grounded screened transformer).

The use of the auto-transformer does not allow the insulation between mains and power stage (and consequently

the motor) anymore. It is then mandatory to mount a correctly sized circuit-breaker inside the rack in the event of

a short-circuit (rectifier bridge, power bridge, motor). Further, the AMP. READY information (pins 18-19 of X4)

must be used for opening the power relay if a failure occurs.

ELECTROMAGNETIC COMPATIBILITY

A common mode inductance is mounted on the motor output and the auxiliary supply is also equipped with a

mains filter . In order to keep the conformity with the EN 55011 standard, group 1, class A, the mains filter on the

power is optional and must be mounted before the 220 VAC three-phase input.

The GROUNDING of the "BF" rack chassis is MANDATORY in order to avoid any physical damage in case of

defective mains insulation.

INFRANOR will withdraw any warranty on items that do not meet these requirements .

IMPORTANT


BF RACK

7 – MAINS FILTER OPTION

The mains filter is MANDATORY for the conformity with the CE certification.

Curve n° 11 shows the conduction level for an average detection, according to the EN 55011 standard, group 1,

class A, with a rack connection via an autotransformer (5 dB overshoot at 250 kHz).

Curve n° 26 shows the improvement obtained with the mains filter. It allows a 10 dB margin with regard to the

maximum level authorized by the standard.

CURVE N° 11


BF RACK

CURVE N° 26

MAINS FILTER CONNECTION

The mains filter must be connected as near the BF rack as possible (max. 30 cm). A metallic braiding must

connect the filter ground terminal to a fastening screw of the BF rack in order to get the equipotentiality. It is

recommended to use the cabinet housing for ensuring the equipotentiality.

The current rating must correspond to the rack current rating, that is:

- FT 35 --à 35 A,

- FT 70 --à 70 A.

8 – SPECIAL CONNECTION REQUIREMENTS

Wiring and ground connections must be very carefully made.

CAUTIONLow potential cables MUST NEVER run in the proximity of high potential cables.

NC, amplifier, motor and machine housing must be grounded via connections as short as possible. Use the

cabinet housing for the equipotential. Use rather braidings than wires, even thick ones.

Keep the equipotential between NC/amplifier, machine housing and motor.

The connectors must be metallic or metal plated (according to the CEI 801 standard ) and must allow "360°"

shield connections.


BF RACK

The reference potential is the earth (ground).

The input command and the logic cables MUST be shielded.

The motor cable MUST be shielded and connected over 360° at both ends. Connect the shield on the motour or

machine housing by means of a metallic collar, as close to the motor as possible, after having removed the paint

if the connector is not metallic.

The sensor cable must be shielded. The correct sensor wiring is an absolutely necessary condition for the

correct operation of the amplifier. If these requirements are not answered, the described specifications will not be

obtained. Further, the wiring will not comply with the EMC requirements and will commit the user's own

responsibility.

The shield connections must be made as follows:

The connector housing is metallic or plated and allows an "360" shield connection, according to the CEM- CEI 801 - 2 - 3 - 4 - 5 recommendations.
