1.5 System block introduction
Lenze pursues the principle to describe functions of the controller by means of function
blocks (FB). This principle is also described in the standard IEC 61131−3.
ƒ Functions that you can use in your project as software functionalities, are contained
in the function libraries as function blocks or functions.
ƒ Moreover, quasi hardware functions are available as system blocks(SB).
1.5.1 System blocks ˘ principle
ƒ System blocks partly respond to real hardware.
ƒ The system blocks are assigned/identified via node numbers. ( 22)
ƒ The inputs/outputs of the system blocks are assigned via:
– System variables ( 23)
– Absolute memory addresses ( 24)
Preface and general information
System block introduction
System blocks ˘ principle
1
ƒ Inputs/outputs are always classified from the program’s point of view.( 24)
ƒ Required system blocks must be explicitly integrated into the project of the DDS via
the control configuration. ( 26)
The system block principle can be perfectly explained by means of a PLC system in a rack:
ƒ Besides the CPU, the rack includes digital I/Os, analog I/Os, counter cards,
positioning cards etc. as extension cards:
CPU
ƒ The CPU can directly access the extension cards and process the resulting
information.
ƒ The single extension cards have a permanent address for being addressed.
xxxxxx
x = extension cards
Tip!
In case of the ECSxA... axis modules, the system blocks correspond to these
attachment cards!
System blocks therefore are specific (hardware) function blocks which are
firmly integrated into the runtime system of the ECSxA... axis module.

General safety and application notes for Lenze controllers
Application as directed
Controllers are components which are designed for installation in electrical systems or
machines. They are not to be used as domestic appliances, but only for industrial purposes
according to EN 61000−3−2.
When controllers are installed into machines, commissioning (i.e. starting of the operation
as directed) is prohibited until it is proven that the machine complies with the regulations
of the EC Directive 2006/42/EC (Machinery Directive); EN 60204 must be observed.
Commissioning (i.e. starting of the operation as directed) is only allowed when there is
compliance with the EMC Directive (2004/108/EC).
The controllers meet the requirements of the Low−Voltage Directive 2006/95/EC. The
harmonised standard EN 61800−5−1 applies to the controllers.
The technical data and supply conditions can be obtained from the nameplate and the
documentation. They must be strictly observed.
Warning: Controllers are products which can be installed in drive systems of category C2
according to EN 61800−3. These products can cause radio interferences in residential areas.
In this case, special measures can be necessary.
2
Transport, storage
Please observe the notes on transport, storage, and appropriate handling.
Observe the climatic conditions according to the technical data.
Installation
The controllers must be installed and cooled according to the instructions given in the
corresponding documentation.
The ambient air must not exceed degree of pollution 2 according to EN 61800−5−1.
Ensure proper handling and avoid excessive mechanical stress. Do not bend any
components and do not change any insulation distances during transport or handling. Do
not touch any electronic components and contacts.
Controllers contain electrostatic sensitive devices which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this

This documentation contains information on installation in compliance with EMC
(shielding, earthing, filter, and cables). These notes must also be observed for CE−marked
controllers. The manufacturer of the system is responsible for compliance with the limit
values demanded by EMC legislation. The controllers must be installed in housings (e.g.
control cabinets) to meet the limit values for radio interferences valid at the site of
installation. The housings must enable an EMC−compliant installation. Observe in
particular that e.g. the control cabinet doors have a circumferential metal connection to
the housing. Reduce housing openings and cutouts to a minimum.
Lenze controllers may cause a DC current in the PE conductor. If a residual current device
(RCD) is used for protection against direct or indirect contact for a controller with
three−phase supply, only a residual current device (RCD) of type B is permissible on the
supply side of the controller. If the controller has a single−phase supply, a residual current
device (RCD) of type A is also permissible. Apart from using a residual current device (RCD),
other protective measures can be taken as well, e.g. electrical isolation by double or
reinforced insulation or isolation from the supply system by means of a transformer.
Operation
If necessary, systems including controllers must be equipped with additional monitoring
and protection devices according to the valid safety regulations (e.g. law on technical
equipment, regulations for the prevention of accidents). The controllers can be adapted to
your application. Please observe the corresponding information given in the
documentation.
After the controller has been disconnected from the supply voltage, all live components
and power terminals must not be touched immediately because capacitors can still be
charged. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation.
Notes for UL−approved systems with integrated controllers: UL warnings are notes that
only apply to UL systems. The documentation contains special UL notes.

ƒ I
x t monitoring is based on a mathematical model which calculates a
thermal motor load from the detected motor currents.
ƒ The calculated motor load is saved when the mains is switched.
ƒ The function is UL−certified, i.e. no additional protective measures are
required for the motor in UL−approved systems.
ƒ However, I
the motor load could not be detected as for instance changed cooling
conditions (e.g. interrupted or too warm cooling air flow).

Safety instructions
Residual hazards
Protection of persons
ƒ Before working on the axis module, check that no voltage is applied to the power
terminals, because
– the power terminals +UG, −UG, U, V and W remain live for at least 3 minutes after
mains switch−off.
– the power terminals +UG, −UG, U, V and W remain live when the motor is stopped.
ƒ The heatsink has an operating temperature of > 70 °C:
– Direct skin contact with the heatsink results in burns.
ƒ The discharge current to PE is > 3.5 mA AC or. > 10 mA DC.
– EN 61800−5−1 requires a fixed installation.
– The PE connection must comply with EN 61800−5−1.
– Comply with the further requirements of EN 61800−5−1 for high discharge
currents!
Device protection
ƒ All pluggable connection terminals must only be connected or disconnected when
no voltage is applied!
ƒ The power terminals +UG, −UG, U, V, W and PE are not protected against polarity
reversal.
– When wiring, observe the polarity of the power terminals!
ƒ Power must not be converted until all devices of the power system are ready for
operation. Otherwise, the input current limitation may be destroyed.
Frequent mains switching (e.g. inching mode via mains contactor) can overload and
destroy the input current limitation of the axis module, if
ƒ the axis module is supplied via the ECSxE supply module and the input current
limitation is activated depending on the DC−bus voltage (C0175 = 1 or 2).
ƒ the axis module is not supplied via a supply module delivered by Lenze.
ƒ the low−voltage supply (24 V) is switched off.
For this reason allow a break of at least three minutes between two starting operations!
Use the safety function ˜Safe torque off˜ (STO) for frequent disconnections for safety
reasons.

4.1 Important notes
ƒ Axis modules of the ECS series provide IP20 enclosure and can therefore only be
used for installation in control cabinets.
ƒ If the cooling air contains air pollutants (dust, fluff, grease, aggressive gases):
– Take suitable preventive measures , e.g. separate air duct, installation of filters,
regular cleaning.
ƒ Possible mounting positions:
– Vertical at the mounting plate
– DC bus connections (X23) at the top
– Motor connection (X24) at the bottom
ƒ Maintain the specified clearances (above and below) to other installations!
– If the ECSZS000X0B shield mounting kit is used, an additional clearance is
required.
– Ensure unimpeded ventilation of cooling air and outlet of exhaust air.
– Several modules of the ECS series can be installed in the control cabinet next to
each other without any clearance.
ƒ The mounting plate of the control cabinet
– must be electrically conductive.
– must not be varnished.
ƒ In case of continuous vibrations or shocks use shock absorbers.

4.3 Mounting with thermal separation (push−through technique)
For the push−through technique the rear panel of the control cabinet must be a steel plate
with a thickness of at least 2 mm.
The edges of the mounting cutout and the fixing holes for the clamps must be slightly
curved inwards (towards the axis module).
Cooling
With the separated heatsink the heat generation in the control cabinet can be reduced.
ƒ Distribution of the power loss:
– approx. 65 % via separated cooler
– approx. 35 % in the inside of the axis module
ƒ Protection class of the separated cooler: IP54
– The sealing surface at the heatsink of the axis module must rest completely
against the mounting plate.
– Use a liquid thread sealant to bond the screws of the clamps.
4
ƒ For sufficient cooling of the drive system:
– Air flow behind the rear panel of the control cabinet must be ³ 3 m/s (e.g. by means
of a collective fan).
ƒ With sufficient cooling, the rated data of the axis modules remain valid.

5.1 Installation according to EMC (installation of a CE−typical drive system)
General information
ƒ The electromagnetic compatibility of a machine depends on the type of installation
and care taken.Especially consider the following:
– Assembly
– Filtering
– Shielding
– Earthing
ƒ For diverging installations, the evaluation of the conformity to the EMC Directive
requires a check of the machine or system regarding the EMC limit values. This for
instance applies to:
– Use of unshielded cables
– Use of collective interference filters instead of the assigned RFI filters
– Operating without RFI filters
ƒ The compliance of the machine application with the EMC Directive is in the
responsibility of the user.
– If you observe the following measures, you can assume that the machine will
operate without any EMC problems caused by the drive system, and that
compliance with the EMC Directive and the EMC law is achieved.
– If devices which do not comply with the CE requirement concerning noise
immunity EN 61000−6−2 are operated close to the ECS modules, these devices may
be electromagnetically affected by the ECS modules.
58
EDBCSXA064 EN 3.2
Electrical installation
Installation according to EMC (installation of a CE−typical drive system)
Assembly
ƒ Connect the ECS modules, RFI filters, and mains choke to the earthed mounting
plate with a surface as large as possible:
– Mounting plates with conductive surfaces (zinc−coated or stainless steel) allow for
permanent contact.
– Painted plates are not suitable for an EMC−compliant installation.
ƒ If you use the ECSxK... capacitor module:
– Install the capacitor module between the power supply module and the axis
module(s).
– If the total cable length in the DC−bus connection is > 5 m, install the capacitor
module as close as possible to the axis module with the greatest power.
ƒ If you use several mounting plates:
– Connect as much surface of the mounting plates as possible (e.g. with copper
bands).
ƒ Ensure the separation of the motor cable and the signal or mains cables.
5
ƒ Avoid a common terminal/power strip for the mains input and motor output.
ƒ Lay the cables as close as possible to the reference potential. Freely suspended
cables act like aerials.
Filters
Only use RFI filters and mains chokes which are assigned to the power supply modules:
ƒ RFI filters reduce impermissible high−frequency interferences to a permissible value.
ƒ Mains chokes reduce low−frequency interferences which in particular depend on the
motor cables and their lengths.
EDBCSXA064 EN 3.2

Electrical installation
Installation according to EMC (installation of a CE−typical drive system)
Shielding
ƒ Connect the motor cable shield to the axis module
– with the ECSZS000X0B shield mounting kit.
– extensively to the mounting plate below the axis module.
– Recommendation: For the shield connection, use earthing clamps on bare metal
mounting surfaces.
ƒ If contactors, motor protection switches or terminals are located in the motor cable:
– Connect the shields of the connected cables to each other and connect them to the
mounting plate, too, with a surface as large as possible.
ƒ Connect the shield in the motor terminal box or on the motor housing extensively to
PE:
– Metal glands at the motor terminal box ensure an extensive connection of the
shield and the motor housing.
ƒ Shield UG cables and control cables from a length of 0.3 m:
– Connect both shields of the digital control cables.
– Connect one shield end of the analog control cables.
– Always connect the shields to the shield connection at the axis module over the
shortest possible distance.
ƒ Use of the ECS modules in residential areas:
– Additionally dampen the shield in orde r to lim it the interfering radiation: ³1 0 d B . This can be achieved
by using standard, closed, metallic, and earthed control cabinets or boxes.
Earthing
ƒ Earth all metallically conductive components (e.g. ECS modules, RFI filters, motor
filters, mains chokes) using suitable cables connected to a central earthing point (PE
rail).
ƒ Maintain the minimum cross−sections prescribed in the safety regulations:
– For EMC not the cable cross−section is important, but the surface of the cable and
the contact with a cross−section as large as possible, i.e. large surface.

Stop!
ƒ Always operate the ECS power supply modules with a brake resistor.
ƒ A parallel wiring of internal and external brake resistor is not permissible!
ƒ Implement the thermal contact of the brake resistor into the system
monitoring so that the mains supply of the power supply module will be
switched off in case the brake resistor will be overheated.
ƒ Read the documentation for the external brake resistor. Observe the safety
instructions contained therein.
If the power supply module needs a high amount of braking power when it comes as
standard built−in unit or in push−through technique design (ECSEE / ECSDE), an external
and more powerful brake resistor can be connected instead of the internal brake resistor.
A power supply module in cold plate technique design (ECSCE) is not provided with an
internal brake resistor so that this version always requires an external brake resistor
(Rbext).
ƒ Connect the brake resistor to X22/BR1 and X22/+UG.
ƒ Connect the thermal contact (NC contact) of the external brake resistor to X6/T1
and X6/T2.

For the supply of the control electronics an external 24 V DC voltage at terminals X6/+24
and X6/GND is required.
Stop!
ƒ The control cables must always be shielded to prevent interference
injections.
ƒ The voltage difference between X6/AG, X6/GND and PE of the axis module
may maximally amount to 50 V.
ƒ The voltage difference can be limited by:
– overvoltage−limiting components or
– direct connection of X6/AG and X6/GND to PE.
ƒ The wiring has to ensure that for X6/DO1 = 0 (LOW level) the connected axis
modules do not draw energy from the DC bus. Otherwise, the power supply
module may be damaged.

Switch−on sequence for the auxiliary relay
Stop!
Overload of the charging connection in the power supply module
The controller enable for the axes may only take place when the charging
process of the DC bus is completed and the power supply module is ready for
operation.
Possible consequences:
ƒ Destruction of the power supply module
Protective measures:
ƒ Use of switching the central controller enable for the axes via the inputs and
outputs DI2 and DO1 of the power supply module (see the following
descriptions).
The switch−on sequence of the auxiliary relay (see Fig. 5−8) is as follows:
1. The digital input X6/DI1 (power supply enable) of the power supply module is
switched to HIGH by the higher−level control or by the operator.
– The DC bus is charged.
2. The ready for operation output of the axis module (DO1) now switches the X6/DI2
digital input (central controller enable) of the power supply module via the relay .
– In the default Lenze setting of the ECS axis modules, DO1 is set to "ready". "Ready"
is only present if a specified DC−bus voltage has been reached.
3. The central controller enable for the axis module takes place via the X6/DO1 output
of the power supply module. The central controller enable DO1 only switches if the
charging process of the DC bus is completed AND the X6/DI2 input is set.

Safe torque off
5.3.3 Safe torque off
The axis modules support the "safe torque off" safety function (formerly "safe standstill"),
"protection against unexpected start−up", in accordance with the requirements of
EN ISO 13849−1, Performance Level Pld. For this purpose, the axis modules are equipped
with two independent safety paths. The Performance Level Pld is obtained if the output
signal is additionally checked with regard to correctness at X6/SO.
5.3.3.1 Implementation
In the axis module, the "safe torque off" connection is implemented with optocouplers.
The optocouplers isolate the following areas electrically from each other:
ƒ The digital inputs and outputs:
– input X6/SI1 (controller enable/inhibit)
– input X6/SI2 (pulse enable/inhibit)
– brake output X6/B+, B−
– output X6/SO ("safe torque off" active/inactive)

5.3.3.2 Functional description
The "safe torque off" state can be initiated any time via the input terminals X6/SI1
(controller enable/inhibit) and X6/SI2 (pulse enable/inhibit). For this purpose a LOW level
has to be applied at both terminals:
ƒ X6/SI1 = LOW (controller inhibited):
The inverter is inhibited via the microcontroller system.
ƒ X6/SI2 = LOW (pulses inhibited):
The supply voltage for the optocouplers of the power section driver is switched off,
i. e. the inverter can no longer be enabled and controlled via the microcontroller
system.
The input signal at X6/SI2 to the hardware is additionally directed to the
microcontroller system and is evaluated for the state control there. For the external
further processing a HIGH level is output for the state "safe torque off active" at the
digital output X6/SO.
The control of the inverter thus is prevented by two different methods that are
independent of each other. Therefore an unexpected start−up by the motor is avoided.

5.3.3.3 Important notes
Electrical installation
Control terminals
Safe torque off
Danger!
When using the "safe torque off" function, additional measures are required
for "emergency stops"!
There is neither an electrical isolation between motor and axis module nor a
"service" or "repair switch".
Possible consequences:
ƒ Death or severe injuries
ƒ Destruction or damage of the machine/drive
Protective measures:
An "emergency stop" requires the electrical isolation of the motor cable, e.g.
by means of a central mains contactor with emergency stop wiring.
Installation/commissioning
ƒ The "safe torque off" function must only be installed and commissioned by qualified
personnel.
ƒ All control components (switches, relays, PLC, ...) and the control cabinet must meet
the requirements of EN ISO 13849. These include for instance:
– Switches, relays in enclosure IP54.
– Control cabinet in enclosure IP54.
– All other requirements can be found in EN ISO 13849.
ƒ Wiring with insulated wire end ferrules is essential.
ƒ All safety−relevant cables (e.g. control cable for the safety relay, feedback contact)
outside the control cabinet must be protected, e.g. in the cable duct. It must be
ensured that short circuits between the individual cables cannot occur. For further
measures, see EN ISO 13849.
ƒ If force effects from outside (e.g. sagging of hanging loads) are to be expected when
the "safe torque off" function is active, additional measures have to be taken (e.g.
mechanical brakes).
During operation
ƒ After installation, the operator must check the "safe torque off" function.
ƒ The function check must be repeated at regular intervals, but no later than after one
year.

ƒ The diode−capacitor combination prevents the test pulses of the safety switching
device from disturbing the smooth running of the motor, as otherwise a short−time

Safe torque off
Description of the function
ƒ The "PNOZ" safety switching device has a two−channel effect on the controller. In
the case of an emergency stop request the two channels (terminals 14 and 24)
become deenergised. The safety switching device monitors the diagnostic output of
the controller.
ƒ The safety switching device is provided with test pulses at the output side, so that
short circuits within the wiring are detected.
ƒ Diagnostics is effected via the wiring of diagnostic output SO to input Y7 of the
safety switching device. Y7 is the input of the feedback loop which has to be on
HIGH level (+24 V) before the outputs 14 and 24 are activated. There is only HIGH
level if both disconnecting paths have switched off.
ƒ At least once a year a manual test has to be carried out to verify the independence
and cutout ability of the two disconnecting paths.
Manual test of the disconnecting paths
ƒ The disconnecting paths have to be checked individually in succession.
ƒ When any test key (T1, T2) is pressed the motor has to become torqueless
immediately. Additionally the brake has to be applied, since the supply of the brake
is switched off via contact X6/B+.
ƒ When the safety switching device is switched off, or if both pushbuttons are pressed
at the same time, the STO state has to be signalled via the indicator light H1. In all
other states this message has to be inactive.
If a deviation from the response described above is determined, the controller must be
switched off immediately. Eliminate the fault before restarting the controller.

5.5 Wiring of system bus (CAN)
Note!
System bus (CAN)
The ECSxA...axis module can communicate with a higher−level host system
(PLC) or further controllers via both CAN interfaces (X4 or X14).
MotionBus (CAN)
The "MotionBus (CAN)" term expresses the functionality of the CAN interface
X4 in case of ECSxS/P/M... axis modules, where communication takes place
using a higher−level host system (PLC) or further controllers exclusively via the
X4 interface. Interface X14 (CAN−AUX) is exclusively used for parameter setting
and diagnostics.
Basic wiring of the CAN bus networks
The two following schematic diagrams show drive systems with different master value
concepts:
ƒ In Fig. 5−14 a higher−level control assumes the function of the master, e.g. ETC.
ƒ In Fig. 5−15 the function of the master is enabled by a controller intended as master.
In both representations, the master value transmission is effected via the
MotionBus(CAN), interface X4.
The system bus (CAN), interface X14, serves to diagnose and/or parameterise the drives.

5.6 Wiring of the feedback system
You can connect various feedback systems to the axis module:
ƒ Resolver on X7 ( 96)
ƒ Encoder on X8 ( 97)
– Incremental encoder with 5V−TTL level, RS−422
– SinCos encoder with zero track without Hiperface, signal level 1 Vss
– SinCos absolute value encoder (single−turn/multi−turn) with serial communication
(Hiperface® interface), supply voltage 5 ... 8 V
Note!
If a "safe isolation" acc. to EN 61140 between the encoder cable and motor
cable (e.g. by using separating webs or separated trailing cables) is not ensured
on the entire cable length cable due to an installation on the system side, the
encoder cable must be provided with an insulation resistance of 300 V. Lenze
encoder cables meet this requirement.
ƒ We recommend to use Lenze encoder cables for wiring.
ƒ In case of self−prepared cables
– only use cables with shielded cores twisted in pairs.
– Observe the notes on wiring/preparation on the following pages.

5.6.2 Encoder connection
Danger!
Valid when using an operating software up to and including V7.0:
When absolute value encoders are used, uncontrolled movements of the drive
are possible!
If an absolute value encoder is disconnected from the axis module during
operation, the fault OH3−TRIP occurs. If the absolute value encoder now is
connected to X8 again and a TRIP−RESET is carried out, the drive may start up in
an uncontrolled manner with a high speed and a high torque. A SD8−TRIP will
not occur, as would be expected.
Possible consequences:
ƒ Death or severe injuries
ƒ Destruction or damage of the machine/drive
Protective measures:
ƒ If a fault (trip) occurs during commissioning when an absolute value
encoder is used, check the history buffer C0168. If an Sd8−TRIP is at the
second or third place, a reinitialisation is absolutely necessary
purpose, switch off and on again the 24−V supply of the control electronics.
. For this
Via the 9−pole Sub−D−plug X8, you can connect the following encoders:
ƒ Incremental encoder (TTL encoder)
– with two 5 V complementary signals (RS−422) that are electrically shifted by 90°.
– with zero track that can be connected optionally.
ƒ Sin/cos encoder (singleturn or multiturn rotary transducer)
– with supply voltage (5 ... 8 V).
– with serial communication.
The initialisation time of the axis module is extended to approx. 2 s.
The controller supplies the encoder with voltage.
Use C0421 to set the supply voltage V
