Technical information
!Warning: High leakage current
As a result of the high switching frequencies, capacitances (parasitic and
integrated) with respect to ground may cause high leakage currents. This is the
reason that a permanent PE connection is required at the control cabinet and
at the line filter!
Measures according to EN 50178/94 Part 5.3.2.1 must be implemented, e.g.
1. Copper protective conductor with a minimum cross–section of 10 mm2
should be connected, or
2. A second conductor should be connected in parallel with the protective
conductor through separate terminals.
This conductor must also fully meet the requirements for PE conductors
according to IEC 364–5–543.

Note
The SIMODRIVE 611 drive converter system can be directly connected to TN
line supplies with rated voltages 3–ph. 380 V AC (with derating), 3–ph. 400 V
AC, 3–ph. 415 V AC and 3–ph. 480 V AC. Matching transformers, which are
tailored to the system, are available to connect the system to other line supply
types, for example, to IT or TT line supplies.
Upstream devices providing protection against hazardous leakage currents or
for fire protection (such as residual–current protective devices) must be
AC/DC–sensitive in accordance with the requirements of DIN EN 50178. In the
case of other residual current protective devices, a transformer with separate
windings must be connected upstream of the converter for purposes of
decoupling. See Chapter 7.
!Warning
When electrical equipment is operated, certain parts of this equipment are
inevitably under dangerous voltage.
Incorrect handling of these units, i.e. not observing the warning information, can
therefore lead to death, severe bodily injury or significant material damage.
Only appropriately qualified personnel may commission/start up this
equipment.
These personnel must be thoroughly familiar with all warnings and
maintenance procedures described in these operating instructions.
Perfect, safe and reliable operation of the equipment assumes that it has been
appropriately transported and repaired and professionally stored, mounted and
installed as well as carefully operated and serviced. Failure to observe these
requirements can endanger the user (electrical shock, fire hazard) or damage
the device.
Hazardous axis motion can occur when working with the equipment.
Further, all of the relevant national, local land plant/system–specific regulations
and specifications must be taken into account.
!Caution
The DC link discharge voltage hazard warning in the local language must be
clearly attached to the appropriate modules.
Note
When handling cables, please observe the following:
Sare not damaged
Sthey may not be stressed,
Sthey may not come into contact with rotating components.

Notice
M600 and M500 are not PE voltages. Hazardous voltages of between
300 ... 400 V with respect to PE are present at the terminals. These potentials
(voltages) may not be connected to PE.
Note
The machine builder must ensure that the voltage drop between the start of the
consumer’s installation and the power drive system (PDS) does not exceed 4%
when operating with rated values.
!Warning
The ”protective separation” can only be guaranteed when using the
components permitted/certified by Siemens for the system.
”Protective separation” can only be guaranteed when it is absolutely certain
that the system components have the appropriate degree of protection.
The ensure ”protective separation”, the shield of the brake cable must be
connected to PE through the largest possible surface area.
”Protective separation” is required between the temperature sensor and motor
winding.
If these limitations and constraints are not carefully observed then this can
result in injury due to electric shock.
!Warning
Start–up/commissioning is absolutely prohibited until it has been ensured that
the machine in which the components described here are to be installed, fulfills
the regulations/specifications of the Directive 89/392/EEC. If this is not
observed, this can result in injury.
!Warning
The information and instructions in all of the documentation supplied and any
other instructions must always be observed to eliminate hazardous situations
and damage.
SFor special versions of the machines and equipment, the information in the
associated catalogs and quotations applies.
SFurther, all of the relevant national, local land plant/system–specific
regulations and specifications must be taken into account.
SAll work should be undertaken with the system in a no–voltage condition!
If this is not observed, this can result in injury.

SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
!Warning
Even after the disconnection of all power, a dangerous residual voltage as high
as 60 V DC can still be present. For capacitor modules, this hazardous voltage
can be present for up to 30 min.
In order to ensure that no hazardous voltages are present, the voltage must be
first carefully measured (generator principle when motors are rotating). If this is
not observed, then this can result in injury due to electric shock.
For this reason, opening the device or removing the cover is permitted only
after up to 30 minutes have elapsed (depending on the degree of expansion)
since the device was switched to the voltage–free state. All covers must be
reattached before the line voltage is switched on. Operation of the plant with
damaged DC link covers is not permitted!
Danger of death!
Touching live terminals, cables or device parts can result in serious injury or
death!
!Warning
Do not switch off devices, e.g. using a line supply isolating device (main
switch), before disabling the pulse inhibit (T 48) on the infeed/regenerative
feedback modules. Otherwise, the device can be destroyed along with other
devices in the control cabinet.
!Warning
The rated current of the connected motor must match the rated converter
current. If this is not the case, then the protection of the motor cables is no
longer guaranteed. The cross–section of the motor feeder cable must be
dimensioned for the rated drive converter current. If this is not carefully
observed, cables can overheat and can even cause an equipment fire.
Caution
When using mobile radios (e.g. cellular phones, mobile phones, 2–way radios)
with a transmission power of > 1 W close to the equipment (< 1.5 m) the
function of the equipment can be disturbed.
Note
This device/module is an open–type device corresponding to UK 50 and, thus,
may only be operated in enclosures/cabinets that ensure protection against
mechanical damage. To ensure protection against mechanical damage, the
devices may only be operated in enclosures/cabinets with degree of protection
IP54 in accordance with EN 60529.

Note
The terminal blocks of the SIMODRIVE 611 modules are used for electrical
connection of the particular module. If the terminal blocks are used for another
purpose (e.g. to carry the module), this can damage the module. If the
insulation is damaged, then this can cause injury due to electric shock.
Note
For a minimum fault current, the machine manufacturer must ensure that the
upstream overcurrent protection devices trip within 5 s (see Chapter 7.3; Table
7–5 and Fig. 7–8
Note
The following secondary conditions/limitations must be carefully observed if the
machine is subject to a high–voltage test:
1. Power–down the unit.
2. Withdraw the overvoltage module in order to prevent the voltage limiting
responding.
3. Disconnect the line filter so that the test voltage does not dip.
4. Connect M600 to PE through resistor 100 kΩ(the grounding clip in the NE
modules is open). In the factory, the units are subject to a high–voltage test
at 2.25 kVDC phase–PE. The NE modules are shipped with the grounding
clip open.
5. The maximum permissible voltage for a high–voltage machine test is
1.kVDC phase–PE.
!Danger
The control and drive components for a power drive system (PDS) are allowed
for industrial and commercial use in industrial networks. Their use in public
networks requires a different configuration and/or additional measures.

ElectroStatic Discharge Sensitive Devices
Components, which can be destroyed by electrostatic discharge are individual
components, integrated circuits, or boards, which when handled, tested, or
transported, could be destroyed by electrostatic fields or electrostatic
discharge. These components are referred to as ESDS (ElectroStatic
Discharge Sensitive Devices).
Handling ESDS modules:
SWhen handling devices which can be damaged by electrostatic discharge,
personnel, workstations and packaging must be well grounded!
SGenerally, electronic modules may not be touched unless work has to be
carried out on them.
SPersonnel may only touch components if
– they are continuously grounded through ESDS wristlets,
– they wear ESDS shoes, ESDS shoe grounding strips in conjunction with
an ESDS floor surface.
SBoards/modules must only be placed on conductive surfaces (table with
ESDS surface, conductive ESDS foam, ESDS packaging, ESDS transport
container).
SModules may not be brought close to data terminals, monitors or television
sets (minimum clearance to the screen > 10 cm).
SDo not bring ESDS–sensitive modules into contact with chargeable and
highly–insulating materials, such as plastic sheets, insulating table tops or
clothing made of synthetic materials.
SMeasuring work may only be carried out on the components if
– the measuring unit is grounded (e.g. via a protective conductor) or
– when floating measuring equipment is used, the probe is briefly
discharged before making measurements (e.g. a bare–metal control
housing is touched).
!Warning
If static discharge occurs on surfaces or interfaces that cannot be easily
accessed, malfunctions and/or defects will result.
!Warning
When the system boots, this represents a critical operating state with increased
risk. In this phase, especially when activating drives, it is not permissible that
personnel are close to the hazardous area.
!Warning
After hardware and/or software components have been modified or replaced, it
is only permissible that the system runs–up and the drives are activated with
the protective devices closed (could possibly result in death). Personnel shall
not be present within the danger zone.
It may be necessary to carry–out a new, partial or complete acceptance test
after every change or replacement.
Before entering the hazardous area, it should be carefully checked that all of
the drives exhibit stable behavior by briefly moving the drives in both directions
(+/–).

!Warning
If the ”safe standstill” function or a stop function, Category 0 in accordance with
EN 60204–1, is activated, the motor can no longer provide any torque. As a
result of this, potentially hazardous motion can occur, e.g. for:
SWhen the drive axes are subject to an external force.
SVertical and inclined axes without weight equalization.
SAxes that are moving (coasting down).
SDirect drives with low friction and self–clocking behavior.
Possible hazards must be clearly identified using a risk analysis that must be
carried out by the manufacturer. Using the assessment based on this risk
analysis, it must be defined as to which additional measures are required (e.g.
external brakes).
!Warning
If the ”safe standstill” function is activated, when a fault condition occurs, the
mechanical axis system can make a jerky movement (possibility of injury,
crushing) as a result of the principle of operation. The magnitude of this
movement depends on the following parameters:
SDesign/configuration and mechanical ratios between the motor/mechanical
system.
SSpeed and acceleration capability of the motor
SMagnitude of the selected monitoring clock cycle.
SSize of the selected standstill tolerance window.
The danger and warning information above must always be unconditionally ob-
served in order to avoid personal injury and property damage.

The professional associations for precision and electrical engineering specify
limits for electrical load in the workplace. Compliance with Federal Emission
Control Law is mandatory in the Federal Republic of Germany!
Adherence to the RFI suppression limits for EMC does not also ensure adher-
ence to the requirements for workplaces.
In particular, machine construction, control cabinet structure, shop environment,
infeed conditions and other installations have a substantial impact on adher-
ence to the limits required by the trade association for the respective workplace.
Therefore, the operator must always clarify whether wearers of pacemakers
may be employed at the planned workplace without endangering their health.

SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
When carrying out a risk assessment of the machine in accordance with the EU
Machinery Directive, the machine manufacturer must consider the following
residual risks associated with the control and drive components of a power drive
system (PDS).
1. Unintentional movements of driven machine components during commis-
sioning, operation, maintenance, and repairs caused by, for example:
– Hardware defects and/or software errors in the sensors, controllers,
actuators, and connection technology
– Response times of the controller and drive
– Operation outside the specification
– Errors when parameterizing, programming and wiring
– Use of radio devices/cellular phones in the immediate vicinity of the
controller
– External effects
2. Exceptional temperatures as well as emissions of light, noise, particles, or
gas caused by, for example:
– Component malfunctions
– Software errors
– Operation outside the specification
– External effects
3. Hazardous shock voltages caused by, for example:
– Component malfunctions
– Static charges
– Operation outside the specification
– Condensation/conductive contamination
– External effects
4. Electrical, magnetic, and electromagnetic fields that can pose a risk to
people with a pacemaker and/or implants if they are too close.
5. Emission of pollutants if components or packaging are not disposed of
properly.
An assessment of the residual risks (see points 1 to 5 above) established that
these risks do not exceed the specified limit values (risk priority number in
accordance with EN 60812 RPZ = 100).
For additional information, refer to the relevant sections of the Configuration
Manual.
At the present time, other known residual risks are:
SAcceleration of the spindle or axes due to:
– Encoder errors, e.g. errors in the absolute measuring system (CD track),
loose contacts in encoder cables or unsuitable encoders.
– Cyclically interchanged phases of the motor connections
(V–W–U instead of U–V–W).
– Interchanged control sense.
– Electric faults (defective components, etc.).
– Operation of a demagnetized synchronous motor with saturation–based
pole position identification.
– Transfer of an incorrect, but plausible actual value in absolute measuring
systems (encoder does not signal an error).

SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
SIf two power transitions in the inverter are simultaneously destroyed, de-
pending on the motor pole number, this can cause brief axis movement.
– Example: Synchronous motor:
For a 6–pole synchronous motor, the maximum mechanical motion
on the motor shaft can be 30 degrees.
With a ballscrew that is directly driven (e.g. 10 mm per revolution) this
corresponds to a maximum linear motion of approximately 0.8 mm.
– Example, synchronous linear motor:
For a synchronous linear motor, the movement can be a maximum of
one pole width, refer to the Motors Configuration Manual.
SFor a 1–encoder system, encoder faults are detected by various HW and
SW monitoring functions. It is not permissible that these monitoring functions
are deactivated and they must be parameterized carefully.
SStop function Category 0 according to EN 60204–1 means that the spindle/
axes are not braked. Depending on the kinetic energy involved, they can
coast–down for a long time.
This must be integrated in the logic of the protective door interlocking (e.g.
with a logic operation with the signal n < nx).
SViolation of limits may briefly lead to a speed higher than the speed setpoint,
or the axis may pass the defined position to a certain extent, depending on
the dynamic response of the drive and on parameter settings (MD).
SParameterization and programming errors made by the machinery construc-
tion OEM cannot be identified. The required level of safety can only be
assured by a thorough and careful acceptance testing.
SWhen replacing power modules or motors, the same type must always be
used as otherwise the selected parameters may result in different re-
sponses.
When an encoder is replaced, the axis involved must be re–calibrated.
SIf the line infeed units are connected to the line supply, where the minimum
short–circuit current is not reached, then the overcurrent protection devices
will not be able to trip within the appropriate time. There is a risk of fire in the
case of a fault!
