The INDRAMAT AC Drive System consists of a supply and the drive modules.
Several drives can be mounted to a single supply module. Supply module
KVR 1.3, with its regeneration capability, is a component of the INDRAMAT
modular AC drive system.
Supply module KVR 1 provides the link circuit d.c. voltage for the power
supply and the control voltage for all connected INDRAMAT main and servodrive modules.

1. Installing the Modular INDRAMAT AC Drive System
1.1. Main functions of supply module KVR 1
Power supply of the
drives
The power rectifier of the KVR rectifies the threephase mains alternating
voltage and provides a regulated link circuit d.c. voltage for the drives power
supply.
The KVR 1 operates as an inverter in the event the drives are generator-driven,
and feeds the power back into the mains. Buffer capacitors provide sufficient
smoothing.
In the event of a power failure, or, if the power supply should be switched off,
then the energy regenerated as a result of the braking of the motors will be
assimilated by the bleeder resistor in the KVR 1.
The KVR1’s internal power contactor makes it possible to isolate the drives
from the mains.
Supply to the
electronics
The KVR supplies the drive module’s electronics via the signal voltage bus. In
the event of a mains failure, the signal voltages will receive power from the
d.c. link circuit. As a result, the drive electronics remain operational when the
drives are in generator mode.
Drive monitoring
system
The KVR has been equipped with extensive monitoring functions. These
communicate with the drive modules via the signal voltage bus.
The Bb1 contact of the KVR is very important for the drive system operation.
The power supply can be connected only when Bb1 contact is closed.

2. Area of Application
2.
Area of application
It is possible to operate the Indramat drives supply modules of the
KVR series at a continuous mechanical rate of 24 kW. The KVR feeds the
regenerated energy created by the braking of the motors back into the mains.
The continuous regeneration power can equal 20 kW. The KVR is thus
particularly well-suited for those applications where high continuous regeneration power is required.
Supply module KDV2, with built-in 2kW bleeder resistor, is available for
smaller continuous regeneration requirements.

2. Area of application
2.5. Functional power features
• It is possible to operate the drives for long periods even while braking
The energy created by braking the motor is fed back into the mains with little
loss of power.
• Direct mains connection
The KVR can be directly connected to 3 x AC 380...480V,
50...60 Hz mains without the use of a transformer.
• Power shutdown with the use of internal contactors
The contactor which shuts down the drive’s power supply is a component of
the KVR1.
• Internal link circuit short-circuit
Internal link circuit short-circuits have the ability to brake synchronous motors
in the event of a problem in the electronics of the motor.
• High overload capability
Peak power of 90 kW to accelerate motors.
• Loss of heat due to energy in the control cabinet
The heatsink is located outside the control cabinet. This makes compact
control cabinets possible.
• Fuse protection is possible with circuit breakers
– Expensive semi-conductor fuses are not needed.
– No special fuses for exports.
• The drive systems reaction to a power failure can be programmed by
adding an external link.
– Without the links, the motors brake at maximum torque.
– With the links, there is a signal to the NC control via a voltageless contact.
Thus, the shutdown of the motors can be guided by the NC. Expensive
tools or workpieces are protected against damage.
• Controlled bridge voltage
No reduction in drive response in the event of mains undervoltage.
• Charging current limiting for bridge capacitors
The inrush current can be ignored when selecting the switchgear for the
power supply. The service life of the switchgear is increased.
• High capacitance of the control voltage
It is possible to connect ten drive modules to one supply module.
• Service friendly
– Signal lines are connected with screw terminals.
– A numeric display makes extensive diagnostics and controlled elimination
of faults possible.

Direct mains
connection
The KVR can be connected to threephase networks with 3 x AC 380...480V,
50...60 Hz without the use of a transformer.
Supply module KVR 1, with its ability to regulate current, offers the lowest
possible mains power without reactive current load.
Current regulators in switched-mode power supplies cause mains system
perturbation, the level of which does not depend on known system conditions
(short-circuit power, mains inductance) at the installation site of the machine.
The KVR is basically operated with a commutation choke to eliminate mains
reactions.
If the link circuit continuous rating is greater than 15 kW, an additional link
capacitor is required (see 3.8).

Each drive module must be separately connected with a ground wire to the PE
busbar of the KVR.
The leakage current coming over the PE conductor exceeds 3.5 mA
AC. As a result, the KVR 1.3 requires a permanent connection.

3. Electrical Connections – Installation Guidelines
Mains connection via a
transformer
If the mains voltage is less than 3 x AC 380 V or greater than 3 x AC 460V, then
a transformer can be used to adapt the mains voltage.
The mains inductance (stray inductance) of transformers can vary considerably dependent upon power and type. For this reason, a commutation choke
will be necessary even when a transformer is used.

3.3. Fuse protection with direct mains connection
The mains connection for KVR 1’s power component with direct mains
connection can be secured with the use of gL-type circuit breakers or fuses.
The fuse rating must not exceed 63 A.
The following recommendations apply to fuses with circuit breakers for direct
mains connections.
If fuses are used, then fuses of the type gL may be used. Semi-conductor
fuses are not required. The fuses selected must correspond to the mains
current.

Grounded threephase
mains
The KVR can be connected to earthed, threephase mains supplies without the
need for potential isolation.
Ungrounded
threephase mains
On non-earthed threephase mains supplies (IT mains), the phase-to-phase
voltage is present during an earth fault between the case and the power
connection of the KVR. The KVR 1 can be protected against overvoltages if
• the KVR 1.3 is connected via a transformer, and
• if the machine is protected by overvoltage conductors.
Connecting the KVR 1.3 via an isolation transformer offers the best protection
against overvoltage and the greatest degree of operating safety.

Overvoltages
• Periodic overvoltages at the KVR 1.3 between the phase conductor (1U1,
1V1, 1W1, 2U1, 2V1, 2W1) and the housing should not be permitted to
exceed 1000V (peak value).

failure.The NC control must then initiate a position controlled shutdown of the
drives within 10 ms for the drive electronics to remain functional. If it takes the
drives more than 10 ms to feed energy back into the link circuit, then additional
capacitors should be used to maintain power supply to the electronics.
An aluminum electrolytic capacitor is recommended due to lack of space.
The voltage between EPU+ and EPU- can reach DC 450V. The

For checking the correct plug connection, the bus connection is terminated
with an end plug. The KVR’s power cannot be switched on without the end
plug. The KVR can also be located in the center of the drive package. In that
case, only one end of the bus connection requires the terminal plug.
The terminal plug is a part of the KVR’s electrical accessories.

3.13. Fault current protective device
It is recommended that the overcurrent fuse (fuse, power circuit breaker)
switch the machine off if there is a short in the housing. If an FI current limiting
type circuit breaker is absolutely required in TT-mains because of the extent
of the grounding resistance, then the following must be noted.
The capacitive leakage currents in switch-mode drives generally flow to earth.
The extent of the leakage current depends on
• the number of drives used
• the length of the motor power cable
• the grounding conditions at the installation site
The leakage current is inevitably increased, if steps are taken to improve the
electromagnetic compatibility (EMC) of the machine (mains filter, shielded
lines). This means that FI current limiting type circuit breakers with nominal
fault currents equal to less than 0.3 A should generally not be used!
False tripping can occur when inductances and capcitances are
switched on (interference suppression filters, transformers,
contactors, magnetic valves).
~
Commercially available pulse current sensitive FI current limiting
_∩_∩ _
type circuit breakers (machine identification
) do not
guarantee the protection of electronic devices with threephase link
circuits (B6 circuit). The protection of electrical apparatus mounted
to a pulse current sensitive FI current limiting type circuit breaker
together with devices which have a B6 circuit, can be affected.
Use either FI current limiting type circuit breakers which switch off with d.c.
fault currents, or mount an isolation transformer into the mains supply line.
If isolation transformers are used, then these should tune the overcurrent
protective device to the impedance of the fault loop so that there is a powering
down given a fault. Connect the star point of the secondary winding with the
protective conductor of the machine.
3.14. Control cabinet check
No voltages other than those specified in the data sheet or in the
interface notes must be connected.
All KVR1 connections must be isolated prior to high-voltage testing

KVR controller
The control signals of the mains contactor and the link circuit short circuit in
the KVR that are suggested by INDRAMAT illustrate the operating principle.
Other controller configurations are outlined in this chapter. The choice of
control and its effect depends upon the range of functions and the sequence
of actions of the whole plant and is the responsibility of the equipment
manufacturer.
4.1. Possible fault responses
A: shutdown due to
fault in drive
electronics
Stopping the drives with or without link circuit short-circuit
In the event of a malfunction in the drive electronics, the link circuit voltage
is shorted as an additional safety measure to brake the drives to a standstill.
With link circuit short-circuits, synchronous motors are always braked to
standstill (MAC or MDD) whether or not the drive electronics are still
operational. Asynchronous motors (2AD or 1MB) are not braked if link circuit
voltage is short-circuited.
Without link circuit short-circuit, functioning drives are braked at maximum
torque. It must, however, be assumed that there will be a slowing down without
electrical braking in those drives where the control electronics are disrupted
or those where regeneration lines are interrupted. The link circuit short-circuit
can only then be obviated, if slowing down without braking will not result in
damage. As an alternative, it is possible to use motors with mechanical
blocking brakes.
How to best shutdown the drives in the event of a problem is, on the
one hand, dependent upon the drive equipment used and, on the
other, on its function. For this reason, only the designer can make
this decision. The following should, therefore, only be seen as a
supportive recommendation for the designer.

B: controlled braking
Controlled braking of the drives during an EMERGENCY STOP (E-stop)
or mains failure with set-point zeroing by the drive electronics, or with
position control by the NC controller.
With an emergency stop or mains failure, the drives are usually stopped by the
drive controller. In the case of an E-stop or if the drives´ internal monitors are
activated, a zero setpoint is initiated by the drive controller and the drives are
braked under control at maximum torque.
In a few applications (e.g., electronically-coupled gear-cutting machines), the
drives have to be stopped under control in the event of an emergency stop or
mains failure. In the case of an E-stop, or if the drives` internal monitors are
activated, the drives are braked under position control by the NC controller.

4.2. Controlling the KVR with link circuit short-circuit
This control type should be selected under normal circumstances!
Application
A high degree of security is obtained with this type of control at low cost. The
monitors built into this drive system are most effectively used.
Typical application:
– if KVR is supplying feed drives only
– if asynchronous main and feed drives are run from one KVR 1.
Features
It is possible to brake the INDRAMAT AC drives even when power is off. It is,
therefore, possible in an emergency to immediately shut off power. The
supply module transforms the energy contained within the momentum of the
drive into heat.
With link circuit short-circuit, synchronous motors are always braked to
standstill, whether the drive electronics are still functioning or not. The link
circuit short-circuit comes into operation only during drive malfunctions. If the
E-stop button is pressed, the asynchronous main drives are also braked.
With an emergency stop or when the KVR´s monitors are activated (e.g.,
mains failure), the drives are braked at maximum torque under the control of
the drive electronics.
Do not close the NCB link on the KVR (X3/1 - X3/2).
Mode of operation
When the E-stop button is pressed, the mains contactor in the KVR 1 drops
out immediately. The drives´ controller enabling signals are disconnected via
an auxiliary contact of the mains contactor. This results in internal set-point
zeroing of all connected drives, which then undergo controlled braking.
A drive fault message via the KVR 1 (Bb1 contact), a fault message via the
NC controller (servo fault), or overruning the limit switches results in the mains
contactor being de-energized and the link circuit short-circuit then comes into
operation.

4.3. Controlling the KVR 1 without link circuit shortcircuit
In exceptional circumstances, power disconnection is adequate to protect the
system from damage when overruning the limit switch or in the event of a
malfunction in the drive electronics.
Typical applications:
– when the KVR 1 is supplying asynchronous drives only
– when the limit switch of the feed drive axis is sufficiently damped
Features
The INDRAMAT AC drives can still brake with power off. This means that
power can usually be immediately switched off in an emergency. The energy
retained in the momentum of the drive is transformed into heat in the bleeder
resistor of the supply module.
The link circuit short-circuit is not short-circuited. With asynchronous drives,
the link circuit short-circuit has no additional braking effect during drive
electronics malfunctions. If the link circuit voltage is shortened, asynchronous
drives can no longer undergo controlled braking.
With an emergency stop or when the KVR 1´s monitors are activated (e.g.,
mains failure), the drives are braked at maximum torque under the control
of the drive electronics.
Do not close the NCB link on the KVR (X3/1 - X3/2).
Mode of operation
The mains contactor in the KVR 1 drops out immediately when the emergency
stop circuit is broken. The drives´ controller enabling signals are disconnected
by an auxiliary contact in the mains contactor. This results in internal set-point
zeroing of all connected drives, which then undergo controlled braking.
If the drive electronics malfunction, the drives run out of control.
Short-circuiting of the link circuit can only be dispensed with, if the
system´s linear axes can run up to their mechanical fixed stop
during a drive malfunction without risk of damage. It is possible, as
an alternative, to use motors with mechanical blocking brakes.

4.4. Controlling the KVR to brake the drives under
position control
Application
In exceptional cases!
Usually in drives that are coupled via the NC controller and which must not
adopt an angular error during a mains failure.
Do not use an NCB link in digital drives with SERCOS interface. The
programmable fault response of digital drives makes a position
controlled braking without an NCB link possible. The NCB link
blocks the message going to the drives that the power supply is
faulty.
Features
The INDRAMAT AC drives can still brake when power is off. This means that
power can be immediately turned off in an emergency. The energy retained
in the momentum of the drive is transformed into heat in the bleeder resistor
of the supply module.
The link circuit voltage is not short-circuited, so energy is available for
stopping the drives under position control.
With an emergency stop or when the KVR´s monitors are activated (e.g, mains
failure), the drives are braked by the NC controller under position control.
The energy stored or regenerated in the link circuit must exceed that required
for exciting asynchronous drives or for return motion.
The NCB link on the KVR (X3/1 - X3/2 ) must be closed. The drives´s
controller enabling signals must not be disconnected by the mains
contactor.
Mode of operation
The mains contactor in the KVR drops out immediately when the emergency
stop circuit is broken. The NC controller must brake the drives under position
control.
With the NCB link in circuit, if the power supply malfunctions, the
set-point zeroing of the drive modules is suppressed. The drives
must always be stopped by the master controller, i.e., the master
controller must evaluate the UD contact of the KVR 1 and stop the
drives when the contact opens. Otherwise, with a faulty power
supply the drives can run uncontrolled.

NC controller
With the NCB link open, a mains fault or a fault inside the drive system is
signalled to the drive. The drives brake at maximum torque. In the case of a
drive fault, the power feed is also disconnected by the internal ready signal of
the KVR.
In a few applications (e.g., electronically-coupled gear-cutting machines), the
drives have to be braked by the NC controller during an emergency stop or a
mains fault.
With the NCB link closed, then set-point zeroing is suppressed in the following
faults:
• faulty power supply
– power failure/phase failure
– link circuit voltage below 200 V
• drive faults
– open-circuit bus connection or faulty end plug
– + 24 VL/ +/- 15 VM signal voltage fault
– overcurrent in the power circuit of the KVR
– bleeder overloaded
– heatsink temperature of the KVR too high
This enables the drives to be stopped under position control during a mains
failure or phase failure. The power regenerated during braking must exceed
power consumption.
During a drive fault, the power supply is always disconnected by the internal
ready signal of the KVR.
With the link closed, due to removal of the set-point zero circuit, the
master controller must ensure that the drives are stopped, i.e., the
master controller must evaluate the UD contact and stop the drives
when the contact opens. Otherwise, if the power feed is removed,
the drives can run uncontrolled.

The signal voltages can be tapped off of terminal strip X3. These terminals
serve measuring and testing purposes. If these voltages are used outside of
the KVR, then make sure that no interference voltages are introduced (short,
shielded leads).
The signal voltage outputs have short-circuit protection. The maximum
permissible loading should not be exceeded so as to prevent damage to the
drives.

The Bb1-contact of the KVR is very important. The Bb1 contact signals that
the drive system is ready for the power to be applied. Only when it is closed,
do the internal interlocks allow the power contactor in the KVR to be
connected.
In the event of a fault, the contactor is disconnected and the Bb1 contact
opens. If the Bb1 contact is open, then a controlled braking of the drives can
no longer be expected. It can, therefore, be used to enable the link circuit
short-circuit to come into operation.
The Bb1 contact closes if the supply to the electronics is applied to the terminal
block X7/2U1/2V1/2W1 and no fault is present.
The Bb1 contact opens during the following faults:
– tachometer fault
– overtemperature in the drive modules
– bridge protection in drive modules
– failure of the ±15 VM / +24 VL signal voltage
– open circuit bus connection or faulty end plug
– temperature of the KVR heatsink too high
– overcurrent in the KVR power circuit
– overvoltage
– bleeder overloaded

6. Fault finding guidelines
6.
Fault-finding guidelines
Because of the resulting production down-time, lengthy fault-finding and
repairs to drive components on the machine are unacceptable.
Thanks to their construction, INDRAMAT a.c. drives enable individual functional units to be easily and completely replaced without adjustments.
This means that in the event of a fault, servicing is limited to fault-location either
on the motor, the supply module or the drive module, or its complete
replacement.
6.1. Fault-finding
Because of the interaction between NC controller, supply and drive modules, motor, mechanical system and position measurement, poor performance of axis movements can be caused either by a fault in the above
devices or if fitted with a comprehensive diagnostic system for rapid fault
location.
6.2. Safety guidelines
There is an increased accident risk when problems occur. Personnel, the plant
and the drives are at risk.
Localization of problems and the elimination of faults should only
be performed by qualified personnel.
Guidelines on
protection of personel
Danger from drive movements:
Undesirable drive movements are possible during the localization of problems.
Unauthorized individuals should not remain within the hazardous
area. Protective measures such as safety bars, covers and photoelectric barriers should not be removed. There must be free and
ready access to the emergency stop switch.
When working within the hazardous area, please note:
When working within the hazardous area, the facility should be
voltage free and secured against being switched on.
Wait out the discharge time (approximately five minutes). Check
intermediate circuit voltage.
• DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96

6. Fault finding guidelines
Danger from live parts
Dangerous electrical loads can occur at the following connections:
• At all connections of the supply module and the corresponding chokes and
capacitors, especially at mains connections 1U1, 1V1, 1W1 and 2U1, 2V1,
2W1, as well as the connections X13 and X14 of the fan supply.
• At the drive modules, at the motor and the plugs of the motor connections.
Before working on electrical equipment:
– Switch power to the facility off with the main switch and secure it
against the possibility of being turned on again.
– Wait for the link circuit to discharge (approximately five minutes).
Check the link circuit voltage.
– Do not run motors. The motor connections will be electrically
loaded if the motor is in motion.
Before turning the equipment on:
Only turn power on if the contact safety, delivered with the unit, is
mounted.
Guidelines on
protecting the machine
To avoid any damage to the machine:
– Only authorized personnel should be permitted to start-up the
facility.
– Secure E-stop and limit switch functions.
Guidelines on
protecting the machine
Prior to switching on:
The wiring should agree with that of the KVR assembly plan. Check
the course of the electricity throughout the unit.
Electrostatic loads
Electrostatic loads endanger electronic components.
Discharge by grounding all objects that come into contact with the equipment.
