1 SAFETY NOTES

Introductory remarks

During operation, the principles on which the converter and motor work, lead to leakage currents to earth which are dissipated by use of the specified protective earth connections which may result in a currentoperated e.l.c.b. on the input side blowing prematurely.

A DC component in the fault current may occur in the event of a short-circuit to frame or earth fault which could make triggering of the higher-level current-operated e.l.c.b. more difficult or even impossible.

Connection of the current controller to the mains using only the current-operated e.l.c.b. is prohibited (preliminary standard EN 50178 / VDE 0160 /11.94, sections 5.2.11 and 5.3.2.1).

The units are protected against direct contact by being installed into common switching cabinets which meet the minimum protection requirements according to EN 50178 / VDE 0160 / 11.94, section 5.2.4.

Sheets of plastic covering the control electronics, the power stage and the device connection, additionally prevent accidental contact during commissioning and casual use of control elements located close to the equipment.

(DIN VDE 0106 Part 100, Accident Prevention Regulation VBG4 ”Electrical Systems and Equipment).

The protective measures and safety regulations according to DIN/VDE are binding for personal security.

Neglecting to fit PE connections on the equipment or the motor will result in serious personal injury and/ or considerable damage of property.

Introduction

2 INTRODUCTION

The power units designated BUM 62 T are used for the upper power range.

Supply part (converter)

The supply part (mains side) for the generation of the DC link voltage is an uncontrolled diode bridge. To reduce the peak making current (deburdening during switch-on), the DC link capacitors are charged via a charge resistor which is bridged by a thyristor after switching-on.

If the typical motor power of the converter on the motor side (see electrical data) is not fully used, e.g., because the power of the connected motor is smaller, the performance of the supply current controller can be used for the connection of other power modules of the BUS 6 series.

The total of all motor powers occurring at the same time must not be higher than the typical motor power.

Starting current load relief

If precautions are not taken, the DC link capacitors produce inadmissibly-large charging current surges from the mains. In order to avoid these surges, the starting current is limited by a load relief device.

To this purpose, a resistance is integrated into the charging circuit. The resistance limits the charging current (with the exception of temporary mains failure) and is bypassed once the DC link is charged.

The cycle time for connect the unit in circuit again is ≥3 min.

If using an additional external capacitor at the DC (external capacity ≥ 500 µF) the cycle time is increased

Introduction

Brake switch

The energy which is generated in the generator mode, is dissipated by the brake switch (brake chopper) and an external regenerative resistor.

Inverter

The inverter on the motor side consists of the IGBT power part and the corresponding sensors. The sensors supply measuring signals for the closed-loop control and also ensure the self-protection of the power electronics. The inverter is triggered by the controller used.

Baumüller rack modules are provided for the control. The drives can therefore be adapted to different applications.

Controller

The BUM 62 T only operates in conjunction with an additional controller. The controller types are equipped with modules. A separate description is available for the operation of the controllers.

Technical data

1. Voltage difference between phases must no exceed +/- 1.0 %.

2. According to EN 61131-2 (Table 5). With a supply voltage < 24 V the fan power is reduced. Therefore, it may be necessary to reduce the output current additionally.

3. All ratings refer to a connection voltage of 400 V and a supply voltage of 24 V.

4. The output voltage is a pulse-commutated DC. The setting range refers to the r.m.s. value of the fundamental wave.

5. The output frequency depends on the controller used.

6. R.m.s. value at an ambient temperature of 40 °C.

7. The unit provides the rated/maximum output current up to the connection voltage. When the input voltage exceeds the rated voltage, reduce the output currents at constant output power proportionally. Characteristic 1: Output currents in relation to the connection voltage.

8. The rated output current must be reduced between 40 °C and 55 °C. The rated output current is calculated according to the following formula:

Example: Rated output current = 100 A, ambient temperature = 46 °C.

The rated output current must therefore be reduced to: 82 A

9. Maximum duration of the peak output current is 120 s. The duration depends on the motor current and the temperature of the heat sink. See Technical Description/Operating Instructions of the controller (V-controller: P139).

10. Chopping frequency of the inverter. (see description parameter P103 in the description of the V-controller)

6.1 Danger information

WARNING

This device carries dangerous voltage and contains dangerous rotating parts (fans). Ignoring the safety and warning information may result in death, severe personal injury and/or damage to material assets.

The user is responsible for the assembly of the converter, the motor, the mains choke and the other devices according to the safety regulations (e.g. DIN, VDE) and all other relevant nations or local regulations concerning the conductor ratings and protection, grounding, disconnectors, overcurrent protection, etc.

The protective measures and safety regulations according to DIN/VDE are binding for personal security. If there are no PE connections on the unit, the commutation choke or the motor, personal injury may be caused since the surface may carry hazardous voltage.

A DC component in the fault current may occur in the event of a short-circuit to frame or earth fault which makes a triggering of the higher-level current-operated e.l.c.b. more difficult or even impossible.

Make the PE connection according to DIN EN 60204 / VDE 0113 Part 1 / 06.93, Section 8.2.2. considering EN 50178 / VDE 0160/11.94, Sections 5.3.2.1 and 8.3.4.4.

Before commissioning check whether the plastic covers over the live parts (power part connections) are in place.

Malfunction of the drive During the initial commissioning, a faulty or uncontrolled movement of the driven machine elements

cannot be excluded. Therefore, proceed with particular care.

Mono Power Unit BUM 62 T 23

Baumüller Nürnberg GmbH 5.99009.03

Page 24

Installation

WARNING

Prior to connecting the drive, carefully check all higher-level safety equipment for perfect functioning, to avoid personal injury.

Special care must be taken when touching the drive shaft directly or indirectly (by hand). This is permissible only when the shaft is at standstill and the converter is de-energized. Machine parts which are freely accessible during operation (shafts, fans, etc.) must be covered.

Protection against contact according to Paragraph 4 Section 4 VBG 4 Protection against direct contact comprises all measures against danger which can result from

touching the active parts of electrical equipment. The active parts must therefore be protected from direct contact by insulation, design, position,

arrangement or firmly installed facilities. Protection refers to common covers, barriers and procedures which ensure that persons are prevented from touching live, active parts.

Switch cabinet must have emergency stop facilities using which all voltages causing dangerous situations, can be switched off. This does not include equipment which, if switched off, would cause another dangerous situation. The releasing element for the emergency stop facility must be arranged such that it can easily be reached in case of danger. In the event of work which is considerably more dangerous that usual, another person must be present.

The operator must ensure that unauthorized persons do not work on the machine.

The operator must report immediately any changes that occur which adversely affect the safety of the unit/system.

When dismantling safety equipment during commissioning, repair and maintenance, ensure that the machine is taken out of commission in accordance with applicable regulations. Remount and check the safety equipment immediately after completing commissioning, repair and maintenance work.

6.2 EMC information

General information on converters

New semiconductor technologies (MCTs and IGBTs) minimize the power loss in the converter by faster switching operation. The size of the power modules is thus more and more decreased. This means that specific requirements must be met for the operation of converters to avoid electromagnetic influences caused by switching operations.

Interferences may be caused by:

y capacitive fault currents. This is caused by high voltage peaks and switching of bipolar transistors

and IGBTs.

1. Supply

2. Auxiliary voltage supply

3. Power stage

4. Switch mode power supply

5. Motor

y high currents and current peaks in the motor cables The interfering energy bound in magnetic fields

reaches frequencies of a few Hertz up to approx. 30 MHz. Due to the high voltage peaks, additional electromagnetic fields occur with frequencies of up to approx. 600 MHz.

y high chopping rates and fast logic circuits (electromagnetic field / 16 MHz .. 1 GHz).

y Mains feedbacks and harmonics. These are caused by commutations and non-sinusoidal mains

loading, particularly for mains-commutated controllers (100 Hz ... 20kHz).

German EMC Law (EMVG)

This converter corresponds to EMVG §5 Section 5, Sentence 3 of EMVG (German EMC Law) dated 09 Nov.92.

"Devices, which are exclusively manufactured or stocked as vendor parts or spare parts for further

processing by industrial companies or craftsmen or by other specialists in the field of electromagnetic compatibility do not need to comply with the protective requirements of Paragraph 4, Section 1, nor do they need EU conformity certification and marking, assuming that the devices in question cannot be run on their own.””

This takes into account that EMC is essentially dependent on the subassemblies of the individual modules and components in the switch cabinet. Regarding the total costs of the machine, it is preferable to suppress interference of an entire system rather than each of its individual components.

The information on the next pages is intended to allow the user to configure his plant according to the latest knowledge in the field of EMC and to comply with legal regulations.

Installation

Measures for ensuring EMC

To ensure EMC you must observe the configuration information below.

Cabling

y To suppress noise emission outside the converter always screen all connected cables.

Also observe the items in Chapter ”Screening”.

26 Mono Power Unit BUM 62 T

5.99009.03 Baumüller Nürnberg GmbH

Page 27

Installation

y You achieve the smallest possible effective antenna height by laying the cable directly on the ground

of the metallic rack.

y You should lay all cables as close as possible to the conductors of the ground system to reduce the

effective loop area for magnetic coupling.

y When laying signal and control cables in parallel across power cables, maintain a minimum distance

of 20 cm between the conductors.

y Cables of different EMC categories should only cross at an angle of 90°.

y For symmetrical signal transmission (e.g. differential amplifier inputs for the speed setpoint), twist

the conductors of each pair together and twist the pairs of wires together.

y The connection between converter and ground plate should be as short as possible (<50 cm). Use

large cross-sections (>10 mm

)

y Sources of noise such as fuses, transformers, chokes and noise-sensitive modules such as

microprocessors, bus systems, etc. should be located at least 20 cm away from the converter and its cabling.

y Avoid reserve loops on long cables.

y The grounding of reserve wires in cables is mandatory (additional screening, avoidance of

capacitively coupled, hazardous contact voltages).

Mono Power Unit BUM 62 T 27

Baumüller Nürnberg GmbH 5.99009.03

Page 28

Installation

Grounding

y To meet EMC requirements, the classical star grounding is no longer sufficient to reduce the noise

of high frequencies caused by converter operation. Better results can be achieved by a reference surface which must be linked to the units’ ground (e.g. bare metal mounting plate and housing parts).

y If a large reference surface is not possible the main equipotential bonding strip should be arranged

directly at the power unit which generates the largest potential steps compared to the other components in the switch cabinet (ground connection < 50 cm if possible).

y To avoid earth loops, apply all ground connectors and screens as close as possible above the

ground.

y If it is possible to ground the controller reference potential of the power unit, make the connection

with as large a cross-section as possible and a short cable (<50 cm).

y Remove insulating layers such as paint, adhesives, etc. from the ground connections. If necessary,

use serrated lock washers (DIN 6798) or similar measures to ensure a permanent, conductive contact. To prevent corrosion on ground connections, use suitable metal combinations (electrochemical series of metals) and keep conductive electrolytes away from the connection by a protective coating (e.g. grease).

y Always connect screens at both ends over a large surface and conductive to ground. This is the only

way to suppress the effects of magnetic or high-frequent noise. If earth loops occur (e.g. double insulation of the setpoint conductor screen), apply the receiver side galvanically and the transmitter side capacitively.

y When laying external cable screens through panels separating different EMC areas, make contact

to the cable screens. Cables which are passed through the panels of screening housings without special measures (e.g. filtering), may impair the screening effect of these housings. For this reason, you must make a conductive connection of the cable screens at the point at which the cable enters the housing. The distance of the last screen contact point to the exit of the cabinet must be as short as possible.

28 Mono Power Unit BUM 62 T

5.99009.03 Baumüller Nürnberg GmbH

Page 29

Installation

Screening

y The screen is effective against magnetic fields when it is connected to ground at both ends.

With electrical fields, the screening is effective if the screen is connected to ground at one end.

For electrical or magnetic fields with high frequencies (depending on the cable length), always apply the screen at both ends because of the linkage (electromagnetic field).

If you apply the screen to ground at both ends, the cable does not leave the screening ”system housing”.

y If you connect cable screens to ground at both ends, the effect of earth loops (potential difference

on the ground system) cannot be excluded totally. However, these are very rare if you observe the measures of the above chapters ”Cabling” and ”Grounding”.

The HF connection of a screen to ground can also be capacitive. This prevents low-frequent noise caused by earth loops. Screen cables passing through different EMC areas must not be separated at the terminals, otherwise the screening would be reduced considerably. They should be led to the next module without interruption.

The screen connection should be of low impedance and over a large surface. Cable tails with a length of only 3 cm (1 cm wire = 10 nH) reduce the screening of up to 30 dB when noise occur in the MHz range!

NOTE

The screen braid must have a coverage of at least 85%. The following cables have a particularly high interference potential:

– Motor cable – Cable to external regenerative resistors – Cable between mains filter and converter

Mono Power Unit BUM 62 T 29

Baumüller Nürnberg GmbH 5.99009.03

Page 30

Installation

y Proposal for the screen connection

Filtering

No filters are necessary for the function of the converter. To maintain EMC regulations, filters at the input or output side may be required.

If you have any queries about the filter dimensioning, please ask for the description ”Baumüller Filters for Mains Applications BFN”.

Filter assembly

y Mount the filter next to the converter. If the cables are longer than 50 cm, screen the mains cable

between converter and filter (grounding at both ends).

y Input and output cables of the filter must be separated physically (distance > 50 cm).

y Connect the filter housing to ground over a large surface.

Leakage currents

Due to the principle of operation, stray capacitances in the filter, power stage, motor cable and motor winding cause leakage currents of 100 mA and higher.

This means that converters with current-operated e.l.c.b. can be incompatible!

Observe the safety information in EN 50178:1994 Section 5.2.11.2.

The power units of the series BUM 62 T are built-in devices according to EN 50178 / VDE 0160 / 11.94, Section 5.2.6 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.1.

Sheets of plastic covering the power connections, additionally prevent accidental contact during commissioning and casual use of control elements located close to the equipment (DIN VDE 0106 part 100, Accident Prevention Regulation VBG4 "Electrical Systems and Equipment).

If the units are to be installed in closed electrical premises according to EN 50178/VDE 0160/11.94, Section 5.2.7 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.2, the user must ensure by additional measures that the requirements according to EN 50178/VDE 0160/11.94, Section 5.2.4 are met.

Mains connection

The power unit is provided for the fixed mains connection to TN and TT mains according to DIN VDE 0100, Part 410/11.83 with a linked mains voltage of up to 3 x 460 V + 15%.

The power unit can be connected to IT mains using an isolating transformer with the neutral grounded at the secondary side.

During operation, the principles on which the converter and motor work, lead to leakage currents to earth which are dissipated via specified protective earth connections and which may result in a currentoperated e.l.c.b. on the input side blowing prematurely. A DC component in the fault current may occur in the event of a short-circuit to frame or earth fault which makes a triggering of the higher-level currentoperated e.l.c.b. more difficult or even impossible. Universal-current sensitive current-operated e.l.c.b. and current-operated e.l.c.b. for AC and pulsating AC fault currents with a rated fault current of 300 mA are suitable.

The connection of the converter to the mains using only the current-operated e.l.c.b. is prohibited (preliminary standard EN 50178 / VDE 0160 /11.94, sections 5.2.11 and 5.3.2.1)

Climatic conditions / Temperature

Concerning climatic conditions, the units of the climatic category 3K3 for sheltered locations acc. to EN 50178/VDE 0160/11.94, Section 6.1, Table 7, Line 3 or acc. to Table 1 of

EN 60721-3-1,2,3,4 under consideration of Note 1 and 3 of EN 50178/ VDE 0160/11.94, Section 6.1. The actual operating temperature range is between 0 to +55 °C. For storage and transport, the specifications of Table 7 (lines 5 and 6) of EN 50178/VDE 0160/11.94, Section 6.1 apply.

Unlike these specifications, the storage and transport temperature of the units may adopt values between -30 and +70 °C (see technical data).

6.4 Safety relay

In this chapter we describe the safety relay.

6.4.1 Methods to avoid an unexpected starting

In order to avoid hazards against persons, for example operators, service- and maintenance technics, the machine has to be kept in a secure condition (safe stop), while interfering in the hazardous area of the machine. That is why a reliable prevention of an unexpected starting is demanded (amongst other things Machine directive 89/392/EWG, appendix I, 1.6.3, last passage; EN 292-2, 4.1.4; EN 60204-1,

5.4). Under unexpected starting is to be understood every starting that can cause a risk when appearing unexpected for persons (EN 292-1). Moreover, besides the transition of the release- to the operating condition of the machine also the unexpected ramp-up of the machine, this means the transition from the safe stop into an unsafe moving has to be considered. This is necessary, because the unexpected ramp-up usually is to be led back to an interruption of the control loop of the machine. In this case the drive is, because of its control system, anxious to achieve highest speed at maximal acceleration. If an unexpected starting occurs, the operator therefore doesn’t have the possibility anymore to remove him self or his hand from the hazard area. This is why the drive has to be stopped and has to be kept safe in its ’off-position’, when having opened, electrical interlocked safety devices. The motor may not have torque and thus cannot generate a dangerous movement.

The prevention of an unexpected starting of the machine can be reached by electrical separated safety devices, e.g. contactors. By some machine types it has to be done without the isolation of the electrical connection of the drive to the mains, if e. g. a drive supplied by a power converter is often stopped and started again. The constant dis- and re-charging of the DC-link represents a big stress for the concerned parts and often leads to disturbing delays and failures of these parts.

The requirement for the starting of a three-phase a. c. motor is the generation of a rotating field, which drives the inductor of the motor. When having variable-speed three-phase current drives, usually in the micro-processors a complex pulse pattern is generated, then the pulses are amplified and are used for the switching of the power semiconductors. If either no defined pulse pattern is available or the amplify ing connection is interrupted, e. g. by switching off of the power supply with a relay (safety relay), no rotary field can be generated. An error by the pulse pattern generation therefore cannot lead to a starting of the motor, as long as the second condition, namely the interruption of the amplifying power supply is available and contrary. The protection against unexpected starting is reached by an electromechanical method which is superior to the electronics. It is reached by a safe isolation - elsewhere than in the load circuit.

The power supply to the windings of the motor is reached at a stoppage by inhibiting the power semiconductor. As semiconductors possibly can fail or be started, because of electromagnetic disturbances, the behavior of the shut down drive has to be considered if such a fault scenario arises. The fail or "ac cidental" turning on of a single or of more power semiconductors at the same DC-link pole does not lead to an uncontrolled starting, as no current flow is accomplished. Not until additionally a further power semiconductor is enabled at another DC-link pole, current is able to flow through the motor. If, thereby the DC-link is directly short-circuited, the fuses which are upstreamed to the converter are tripped, the motor doesn’t start. If the DC-link is "short-circuited" over a winding of the motor, a magnetic field can be set up in the motor. If it is an asynchronous motor, then the generated d. c. magnetic properties cannot cause a lurch of the inductor. By the permanent-magnetic synchronous motor the inductor will rotate into a notch position. The therewith angular movement which is covered is dependable of the inductor’s po sition and the number of pole pairs of the motor. It amounts to maximal 180°/number of pole pairs. Subsequently the enabled DC-link operates like a brake, this means after the ending of the lurching movement the drive is in a blocked condition. A starting of the drive is impossible. If a machine with a synchronous motor is planned, the possible sudden movement must be considered, because it can lead to a dangerous movement. Therefore the machinist must carry out a safety evaluation for the residual movement.

Installation

The function of the safety relay is limited to the prevention of an unexpected starting. The switching of the safety relay, while the inductor of the motor is rotating, causes an uncontrolled "coasting" of the ma chine, a braking with help of the converter is not possible anymore.

WARNING

Both on the motor and at the unit there can be mains voltage although safety relay is switched off. If required, switch the appliance off-circuit like an appliance without a safety relay - the safety relay

does not switch the appliance and the motor off- circuit!

Turning off the safety relay has no isolation from the supply system as a consequence. Therefore, mains potential can be both at the converter and at the motor. The protection against electric hazards has to be therefore saved with other means (for example master switches) when maintaining, servicing or re pairing electrical components of the drive system.

6.4.2 Safety categories

Dependant of the possible hazards (these are rated due to the consideration of the severity of the injuries, the frequency of the length of stay within the hazard area and possibilities in order to prevent hazards) security relevant components of machines have to meet certain safety criteria. The requirements to safety-based parts are divided into five categories in the standard EN 954-1.

In category B basic demands, in 1 additionally safety-technical proved components and principles are claimed. In category 2 an error between inspection intervals can lead to a loss of the safety function.

Category 3 accords to the level “the single-error-certainty to recognize errors partially”. The safety-relevant components must be in such a way, that a single error doesn’t lead to a loss of the safety function, whereat not the complete possible errors can be self-contained recognized by the system. Therefore an accumulation of unrecognized errors can lead to a loss of the safety function.

Category 4 accords to the level “Self-monitoring”. This component recognizes self-contained possible errors and signals these in time of the loss of the safety function. Also if up to three from one another independent errors arise the safety function is always maintained.

6.4.3 The safety relay

The function of the safety relay is executed in fail-safe-technic, also named closed-circuit principle. The safety function “safe stop” is active, as long as no voltage is applied to the input terminals (X68: 3,4). Consequently the functioning of the safety function is guaranteed if power failure takes place. In order to deactivate “safe stop” a voltage of 24 V has to be applied to the terminals, which are intended for this use (X68: 3,4).

For the external error monitoring of the safety relay´, the instantaneous control state can be interrogated at its positively driven status signal contact (X68: 1,2). In case there is no voltage applied to the safety relay (X68: 3,4), that means during the “safe stop”, then the status signal contact is closed (NC contact). Also a parting of a cable can thusly be recognized as an error.

If the voltage at the input terminals of the relay (X68: 3,4) is switched off, then the converter generates one or two error messages (F0204 and/or F0206), which it displays on the V-controller. The drive can only be taken in operation again, if these messages are deleted after a reset of the safety relay with a reset signal from the controller (for example by X26, pin programmable or over the interface to a bus system).

Installation

The closing- and opening sequence of the release signals as well as of the safety relay must be considered in order to assure a faultless operation of the drive.

Sequence diagram of the safety relay

Baumüller-devices of the series BUM 6, BUS 6 and BKH, which are made with one safety relay (optional), comply with the requirements of the category 3 (EN 954-1) for the safety-relevant using “protection against unexpected starting”, if the configuring and installation instructions are complied with.

Before the commissioning of the machine, in which the converter with the safety relay is built in, the safety function “protection against unexpected starting” must be checked. For that purpose a safety device must be executed (for example door contact). The motor must now be zero-torque.

If the reliability performance of the “protection of unexpected starting” once has been determined, then this safety function of the converter doesn’t have to be checked by an external monitoring, as the device checks itself on possible errors and if necessary displays a message as well as turns off the drive.

Application example for machine of category 3

Exemplary the following diagram shows the usage and cabling of a Baumüller converter of the series b maXX in a machine tool, at which the safe taking of work pieces at opened barrier is possible according to category 3 (EN 954-1).

Example for an application for safe stop according to category 3 (EN 954-1)

The switching-off of the electrical drive motor takes place dual-ported.

y S2 (NC contact) and S3 (NO contact) have hardware effects on the pulse release input of the con-

verter (X26: 14). Only if S2 and S3 display a closed cover (and therewith a safe condition) voltage is being applied to the impulse release input of the converter.

y S1 (NC contact) has hardware effects on the safety relay of the converter. Only if S1 displays a

closed cover (and therewith a safe condition) voltage is applied to the safety relay input (X68: 3) and therewith allows a torque generation at the shaft of the motor. The NO contact of S1 is connected with the monitoring circuit.

y The monitoring circuit, a fail-safe monitoring control of the category 3 (EN 954-1), checks on its own

the directly connected switching contacts of the position switch S1 (NO contact), S2 (NO contact) and S3 (NC contact). If the barrier is not completely closed or a theoretical impossible condition of the position switch contacts is present (for example S1 and S2 show a different switching condition or S2 and S3 show the same switching condition), then the control circuit will not get a release signal from the monitoring circuit. A missing release signal of the monitoring device leads to a direct switch ing off of the converter by means of the control circuit. If the monitoring circuit has recognized an error (for example different switch condition of S1 and S2), this is displayed to the operator and a commissioning of the drive is not possible until the error has been repaired.

y The status signal contact of the safety relay (X68: 1,2; NC contact) can additionally be evaluated by

the monitoring circuit (not obligatory).

y The position switches, which are used, must unavoidable have actuated and mechanical connected

contacts as well as a dual-port connection (NC contact/ NO contact). The mechanical operating at the safety device must take place unavoidable, that means tamper-resistant.

The connection cables between the safety relay input (X68: 3,4) and the control as well as between the impulse release input at the converter (X3:5) and the controller must not be installed outside the control cabinet in a common cable channel.

Application example for machine of category 4

Additional procedures when configuring a machine make it possible with a converter of the category 3 (EN 954-1) at safety-relevant operations for the “protection against unexpected starting” also category 4 for the complete drive.

A possibility is the usage of a contactor, with which the external conductors of the motor cable is shortcircuited.

The diagram shows exemplary the usage and cabling of a Baumüller converter of the series BUM 6, BUS 6 or BKH of a machine tool, at which the safe taking of work pieces at opened barrier according to cat egory 4 (EN 954-1) is possible.

Example for an application for safe stop according to category 4 (EN 954-1)

The switching-off of the electrical drive motor takes place three-ported.

y The contactor K1 with three NC contacts short-circuits the current to the motor in the release state

in all poles (closed-circuit current principle), so that no electrical energy of the converter arrives at the motor. S2 (NC contact) and S3 (NO contact) effectuate K1. Only if S2 and S3 display a closed barrier (and therewith a safe condition) K1 starts up and the short-circuit in the motor line is reset.

Mono Power Unit BUM 62 T 37

Baumüller Nürnberg GmbH 5.99009.03

Page 38

Installation

The status signal contact of K1 (NO contact) to the monitoring circuit is constructed with mechanical with the NC contacts connected contacts. The selection of the contactor takes place after its limiting short-time current load capability (10 ms). This must be bigger than the nominal current of the used semiconductor fuses at the mains input of the converter.

y S1 (NC contact) has hardware effects on the safety relay of the converter. Only then if S1 displays

a closed barrier (and therewith a safe condition) voltage is applied to the safety relay input (X68: 3) and therewith makes a torque generation at the shaft of the motor. The NO contact of S1 is connect ed with the monitoring circuit.

y S3 (NO contact) has hardware effects on the impulse release input of the converter (X26: 14). Only

if S3 displays a closed barrier (and therewith a safe condition) voltage is applied to the impulse re lease input of the converter.

y The monitoring circuit, a fail-safe monitoring control of the category 4 (EN 954-1), checks on its own

the directly connected switch contacts of the position switches S1 (NO contact), S2 (NO contact), S3 (NC contact) and the status signal contact of the safety relay (X68: 1,2; NC contact) as well as the contactor K1 (NO contact). If the barrier is not completely closed or a theoretic impossible condition of the position switch contacts is present (for example S1 and S2 show a different switch condition or S2 and S3 show the same switch condition or the status signal contact of the safety relay is opened/closed, although the status signal contact of S1 is closed/opened), the control circuit re ceives no release signal of the monitoring signal. A missing release signal of the monitoring device leads to a direct switching off of the converter by means of the control circuit. If the monitoring circuit has recognized an error (for example different switch condition of S1 and S2), this if displayed to the operator and the commissioning of the drive is not possible until the error has been repaired.

y The position switches, which are used, must unavoidable have actuated and mechanical connected

contacts as well as a dual-port connection (NC contact/ NO contact). The mechanical operating at the safety device must take place unavoidable, that means tamper-resistant.

The connection cables between the contactor K1 and the control circuit as well as between the safety relay input at the converter (X68: 3,4) and the control circuit must not be installed outside the switching cabinet in a common cable channel.

NOTE

All information given in the Operation Manual of the converter, especially the chapters safety instruction, installation and commissioning, must absolutely be observed.

For the use and the installation of the safety devices the legal and official requirements of the government safety organizations and of the EU-Directives for safety requirements at installations and machines (for example EN 60204-1, security of machines, electric equipment and EN 292-2 security of machines general configuration directives) are valid.

6.4.4 Service time

The mechanical service time of the safety relay is at least 1 x 107 cycles of operation.

7.2 Operation

The device is almost exclusively operated via the controller (see controller description).

Reset (acknowledgement) of errors via the optocoupler input ”Reset” of the connector strip X99AB is the only exception from this.

7.3 Monitoring functions and their messages

NOTE

Monitoring functions are active only when the +24V supply voltage (X99A) is applied.

The monitoring functions of BUM 62 T is divided into two groups. The first group is ”Monitoring functions of the supply part”. The second group is ”Monitoring functions of the power part on the motor side”. This division corresponds to the internal design of the unit.

Monitoring functions of the supply part

The messages generated by the ”Monitoring functions of the supply part” are indicated via relay contacts and/or displayed by LEDs. The messages are sent simultaneously to the controller which processes it.

The position of the relay contacts and the LEDs is illustrated on the following figure

For more detailed information on the messages and the LEDs/relay contacts refer to ”Messages via LEDs” page 60 and to ”Messages via relay contacts” page 61.

Monitoring functions of the power part on the motor side

The messages generated by the ”Monitoring functions of the power part on the motor side” are exclusively sent to the controller which processes them.

7.3.1 Ready for operation

The message ”Ready for operation” is the most important message for you. If a monitoring function generates a message which clears the ”Ready for operation” message, the production of your plant is stopped in the worst case.

There is more than one ”Ready for operation” message. If, e.g. a V controller is included in the BUM 62 T, four different ”Ready for operation” messages can be displayed in a drive.

y ”Supply part ready” (available and visible in the BUM 62 T)

= ”Internal ready for operation” (digital output) = "External ready for operation"(relay contacts)

y ”Supply part ready” (available in the BUM 62 T and not visible)

y ”Controller ready” (available in the controller)

y ”Completely ready” (available in the controller)

The message ”Completely ready” depends on the three other ”Ready” messages. The message ”Completely ready” is output only when the messages ”Supply part ready” and ”Power stage ready” and ”Controller ready” are output (see figure).

NOTE

The drive is ready approx. 3.5 seconds after the +24V supply voltage and the mains voltage have been applied.

”Power part ready” after approx. 0.5 s. ”Controller ready” after approx. 3 s

The following sections provide further information on the different ”Ready” messages.

Commissioning

”Supply part ready”

When the ”Monitoring function of the supply part” does not recognize any errors, the monitoring function generates the message ”Supply part ready”.

y If the message ”Supply part ready” is cleared by the monitoring function, the BUM 62 T

disconnects the load from the drive, i.e. the units does no longer supply a torque.

The BUM 62 T displays this message using an LED and supplies it to relay contacts at the same time. For more information refer to

The ”Supply part ready” is also referred to as "Internal ready" (terminal designation BBint) or "External ready" (terminal designation BBext).

Both messages are identical. The difference lies in the internal structure of the unit. At the output of the supply part, ”Supply part ready” is also referred to as ”Internal ready”. After the message of the unit has been passed on to the power part, the message ”Supply part ready” is referred to as ”External ready”.

”Messages via LEDs” page 60 and ”Messages via relay contacts” page 61.

”Power part on the motor side ready”

When the ”Monitoring function of the power part on the motor side” does not recognize and errors, the monitoring function generates the message ”Power part on the motor side ready”.

y If the message ”Power part on the motor side ready” is cleared by the monitoring function,

the BUM 62 T disconnects the load from the drive, i.e. the units does no longer supply a torque.

”Controller ready”

The V controller was mentioned at the beginning of this section. It may be possible that you use another controller. Therefore, we will not provide any further information and refer to the corresponding documentation. The documentation of your controller provides information on whether the message ”Controller ready” is available in the controller you are using and how you can process this message, if available.

”Completely ready”

The above mentioned information applies here as well. The documentation of your controller provides information on whether the message ”Completely ready” is available in the controller you are using and how you can process this message, if available.

1. The V controller always outputs this collective message in the event of an error in the supply part.

The corresponding LED displays on the front of the unit which error has occurred.

2. Trigger reset input (apply +24V and M24V at X99AB, optocoupler input).

Switch off +24V supply voltage.

This clears all messages of the supply part! If you observe the WARNING message, you can bring the drive to a defined operating state before the power unit clears the ”Supply part ready” message and de-energizes.

3. Not possible via the reset input! For safety reasons you have to wait until the DC link has discharged

< 20 V), then switch off +24-V supply voltage.

This clears all messages of the supply part!

4. You must clear this message by a controller reset.

The controller documentation specifies how to display and clear the message.

5. A message occurs only if the safety relay is switched off. The safety relay is switched off only if the

+24V supply voltage for the relay is not applied. Switch on again the +24 V supply voltage for the relay before you can clear the message by a controller reset.

Reset

NOTE

Reset: If the message cannot be reset, it is very likely that the cause of the error has not yet been removed.

Monitoring functions of the supply part

y Phase failure monitoring function

The voltage of all mains phases is monitored. If a mains phase fails, the BUM 62 T generates a WARNING message. If the voltage returns within 10 seconds, the WARNING message is cleared. If the mains phase fails for more than 10 seconds, the WARNING message is cleared and the message ”Phase failure” is stored. The message ”Supply part ready” is cleared.

y Mains failure monitoring function

The voltage of all mains phases is monitored. Two different situations are possible:

1. Two or three mains phases fail and the DC link voltage slowly reduces.

y The WARNING message is set.

y The message ”Mains failure” is output, as soon as the DC link voltage is smaller than 300 V.

y The message ”Supply part ready” and the WARNING message are cleared.

2. Two or three mains phases fail and the DC link voltage reduces very fast

(within a few milliseconds).

y The message ”Mains failure” is output, as soon as the DC link voltage is smaller than 300 V.

y The message ”Supply part ready” is cleared.

y The WARNING message is set (for a few milliseconds).

Reason: If two or three mains phases fail, the procedure ”Output WARNING message” is started. This procedure takes a few milliseconds. If the DC link voltage falls below 300 V within this time, the message ”Supply part ready” is cleared immediately. The WARNING message is then set and cleared immediately since the message ”Supply part ready” is no longer available.

NOTE

After the +24V supply voltage has been switched on, the output of the ”Mains failure” monitoring function is stored only if:

y the mains is recognized to be "okay" and the DC link has fallen below 300 V.

To achieve an automatic restart e.g. after mains interrupt, you can avoid the storing of the messages by a permanent triggering of the reset input (apply +24V and M24V at X99AB, optocoupler input),

provided that the mains failure time > 0 seconds has been set. Refer to ”Mains failure time” in the controller description)

WARNING

If you enable an automatic start of the drive, you cause a severe danger of the operating personnel. If a enable an automatic start of the drive, you must provide a protection on the machine side!

y Monitoring function of short-circuit regenerative circuit output

The connection for the external regenerative circuit is monitored. If the monitoring function recognizes a short-circuit at the connection for the external regenerative circuit, the message ”Short-circuit regenerative circuit” is generated. This message is stored and the message ”Supply part ready” is cleared.

WARNING

A short-circuit of the regenerative circuit may destroy the unit.

Monitoring functions of the power part on the motor side

y Overcurrent (motor) monitoring function

Each of the three motor phase currents is monitored. If the phase current exceeds 30% of the peak value of the permissible peak current, the BUM 62 T generates a message. This message is stored in the BUM 62 T and transmitted to the controller. The message ”Power stage on the motor side ready” is cleared.

NOTE

The overcurrent message and the subsequent stop of the drive protects the drive from damage/ destruction. To avoid the message Overcurrent (motor), you must limit the permissible peak current of the motor phase currents by the control.

y Earth current (short-circuit) monitoring function

The earth fault current of the motor phases is monitored. A message is generated when the fault current exceeds 20 % of the peak value of the permissible peak current of the power part. An earth fault at the motor connection is very probable. This message is transmitted to the controller. The message ”Power part on the motor side ready” is cleared.

y Overvoltage DC link monitoring function

The voltage of the DC link is monitored. If the DC link voltage exceeds 800 V, a message is generated. This message is transmitted to the controller. The message ”Power stage on the motor side ready” is cleared.

NOTE

The DC link voltage can rise until it is switched off if the drive brakes and no or an insufficient regenerative circuit is connected to the DC link.

y Power transistors monitoring function

The collector-emitter saturation voltage is monitored. If the voltage is too high, an overcurrent is applied to the power transistor, caused e.g. by a shortcircuit of the motor terminals and a controlled switch-off procedure switches off the transistor and generates a message. This message is transmitted to the controller. The message ”Power stage on the motor side ready” is cleared.

NOTE

To ensure a recovery of the transistor after a switch-off because of overcurrent, the message can only be reset after at least 5 seconds (typically 10 s).

Commissioning

y Overheat heat sink monitoring function

The temperature of the heat sink is monitored. A linear thermal sensor is located on the heat sink the measured value of which is passed on to the controller. This means the controller is responsible for the temperature monitoring (refer to the controller description) which must be set according to the technical data in the controller description. The message ”Power part on the motor side ready” is cleared.

WARNING

The highest temperature allowed for the heat sink is 90 °C - higher temperatures may destroy the unit .

Adjust the controller in such a way, that ”Power part on the motor side ready” will be cleared by the controller, when the heat sink reaches a temperature of 85 - 90 °C.

y Internal auxiliary voltage monitoring function

The voltage which is used to trigger the power transistors, is monitored. If there is no internal auxiliary voltage, a message is generated. This message is transmitted to the controller. The message ”Power part on the motor side ready” is cleared.

y Safety relay (option)

The switching state of the safety relay is monitored. For further information on the safety relay please refer to ”Messages via relay contacts” page 61.

16. Miscellaneous

a) The inspection of the delivery items ready for acceptance

shall take place in the Baumüller works. The purchaser shall bear the costs of this inspection. In the event that the purchaser fails to perform the inspection, then the delivery items shall be considered as having been delivered in conformity with the contract when they leave the works.

b) The purchaser is obliged to take delivery of goods and

services from Baumüller without delay. Immaterial defects do not entitle the purchaser to refuse the acceptance.

days after notification of the readiness for acceptance on the behalf of Baumüller or after receipt of the contractual service in writing and with exact, examinable specification of reasons that he/she refuses the acceptance, then the acceptance shall be considered as having been declared and the orderly performance of the contract as having been ascertained.

d) The agreed service shall be considered as having been

accepted when the item delivered has been put into operation by the purchaser himself/herself or upon his/her

instructions by third parties beyond the functional test required to carry out the acceptance. This also applies in the event that the purchaser refuses the functional test/the acceptance without sufficient cause.

e) Experts to be designated by both parties shall take part in

the acceptance inspection. The result of the functional test shall be entered in a record to be signed by the purchaser in consideration of the technical specifications.

c) Before the commencement of the erection/installation, the

delivery items required for the commencement of works have to be on site and all preliminary works progressed to the extent that the erection/installation can immediately begin and be completely carried out without interruption.

operation is delayed due to circumstances for which Baumüller is not responsible, then the purchaser shall bear the costs for idle time and journeys required on the behalf of the installation personnel.

e) The installation personnel working time has to be certified

weekly by the purchaser. The purchaser shall present to the installation personnel a written certification regarding the ending of the erection/installation without delay.
