1.1 Summary

The SEC-AC servo regulators are fully digital AC servo regula-
tors which can be adapted very flexibly to a large number of
applications due to their extensive parametrizing possibi-
lities.

The SEC-AC-508 is closely related to the SEC-AC-305. Apart
from the different mains voltage and the connection for an
external braking resistor on the SEC-AC-508, the two devices
are fully compatible.

The SEC-AC Smart Electromotor Controllers must be fitted in a
control cabinet. The circuitry can be carried out in uniform
manner.

1.2 Fatures

– Full integration of all components for the controller and

power units, evaluation of the rotary transducer (motor
angle of rotation feedback) has been designed as a
plug-in module.

– Slot for technological extensions. A CANopen field bus

module as well as a Profibus module are available on re-
quest.

– Integration of all filters in the device necessary for com-

plying with the E MC regulations in operation (industrial
area), e.g. network filter, motor output filter, filter for sup-
plyaswellasfortheinputsandoutputs.

– Integrated braking module with braking chopper enables

braking energy to be dissipated via the internal braking
resistors. Only SEC-AC-508: External resistors with up to
several kW continuous output can be connected for con-
siderable braking energy.

– Only SEC-AC-305:

For increasing the braking output, an additional external
chopper with an additional braking resistor can be used.

– New mechanical concept:

The completely enclosed EMC-optimized metal housing
has been designed for direct mounting and fastening onto
the usual mounting plates in a control cabinet.

– Complete electrical isolation of the controller unit and the

final output stage, digital inputs and outputs, analogue
and control electronics in accordance with VDE 0160.

– 4-quadr ant operation with complete continuous transfer

between the quadrants.

– Droopless control in conjunction with a digital nominal

value specification.

– Sinus-shaped current injection, therefore continuous

torque compared with block-commutated controllers.

– Can be operated as a speed, torque or position regulator.

– Smooth or time-optimum positioning relatively or abso-

lutely to a reference point.

– Speed and rotary angle synchronization with electronic

gears via an incremental sensor input or CAN bus (on
request).

– Short cycle times, the control dynamics are similar to

those of an analogue regulator.

– Simple coupling to a higher-order controller, e.g. to a PLC.

– The digital controller permits error-tolerant operation, i.e.

faults are recognized in good time and regulated when
possible.

1.3 Controller unit

1.3.1 Brief description

The central component in the controller unit is a highly inte-
grated 32-bit RISC micro controller of type HITACHI SH 7032.

Communication with higher-order controllers, PLCs or master
computers is accomplished with the optional CAN bus inter-
face, via the serial interface and via the digital inputs/out-
puts.

The ten external digital inputs and the five digital outputs are
completely electrically isolated.

1.3.2 Analogue-digital converter

The analogue-digital converter is integrated in the SEC-AC. It
digitizes analogue variables, e.g. the motor currents, ana-
logue nominal values or the temperatures of the motor and
the final output stage.

1.3.3 Digital-analogue converter

The digital-analogue conver ter serves for displaying digital
control variables on an analogue monitor. This function is of
help, e.g. with regulator optimizations. The SEC-AC has two
analogue monitor devices.

1.3.4 Internal monitoring

A watchdog timer and extensive monitoring functions ensure
very reliable operation of the controller unit.

The microcontroller and additional external hardware logic
register error signals from the motor, from the rotary-angle
evaluator and from the final output stage.

1.4 Final output stage

1.4.1 Brief description

Final output stage The final output stage is a three-phase design.

The motors should be connected star-shaped, in order to
prevent circulating currents in the motor. The intermediate
circuit voltages comply with the standard European or in-
ternational values.

Operation with lower intermediate circuit voltages is also
possible (with reduction of output). If very fast components
are used, signal distortions will be reduced to a minimum.

1.4.2 Power supply

SEC-AC-305

An external power unit is not necessary for rated outputs in
the dimensioning range. Connection is made via the single-
phase 230 V AC network.

EC-AC-508

These devices can be connected directly to the 400 V three-
phase network.

1.4.3 Feeding back the braking energy

SEC-AC-305 and SEC -AC-508

The braking energy is fed back into the intermediate circuit
where it creates a voltage increase.

Braking chopper with
braking resistor

A braking chopper with braking resistor is integrated in the
final output stage. If a certain limit value of the intermediate
circuit voltage is exceeded during the feedback, the braking
energy will be converted to heat by the internal braking re-
sistors. Control of the braking chopper is carried out by soft-
ware in the SEC-AC. The internal braking resistors are pro-
tected against overload.

SEC-AC-508

If, in a particular application, the output of the internal resi-
stors is not sufficient, an external resistor can be connected
as described in chapter 3.3.2.

Simultaneous operation of the internal and external braking
resistors is not possible. The external resistors are not protec-
ted against overload automatically by the SEC-AC.

SEC-AC-305

If in a special, seldom used application case, the output of
the internal resistors is not sufficient, an additional external
braking chopper with additional braking resistor must be
connected to the intermediate circuit.

Further information can be obtained from Festo.

1.4.4 Internal monitoring

The final output stage will be switched off very quickly by the
controller unit if operating faults occur. A high degree of pro-
tection is ensured for the motor and the SEC-AC.

An extensive arrangement of sensors and monitoring func-
tions ensure operational safety:

– measurement of the motor temperature

– measurement of the final output stage temperature

– recognition of device-internal earth connections (protec-

tive earth)

– recognition of connections between two motor phases

only SEC-AC-508: recognition of connections at the output
for the external braking resistor

– recognition of overvoltages in the intermediate circuit

– recognition of faults in the internal voltage supply

1.6 Rotary transducer evaluation

The rotary transducer evaluating unit is incorporated on a
plug-in board.

Different sensor adaptions are therefore possible. As stan-
dard, the SEC-AC operates with a resolver . It also possesses
an additional incremental sensor input and an incremental
sensor output. The sensor evaluation possesses the following
features:

– a resolver resolution set at 16 bits

– an additional incremental sensor input (synchronizing

input), the resolution can be set, internal 4-fold evaluation

– an additional incremental sensor output with fixed set

resolution of 1024 inc/rev.

The incremental sensor inputs and output can be used, e.g.
for synchronizing several SEC-ACs as electronic gears.

1.6.1 Serial interface

The serial interface with RS 232 specification serves for para-
metrizing the SEC-AC. Parametrizing is carried out in conjunc-
tion with the PC parametrizing progr am for WINDOWS/NT
and a PC.

In applications in which high data transmission and the net-
working of several regulators are not required, the RS 232
can also be used for controlling the regulator.

1. Summary of components

Festo P .BE-SEC-AC-HW- EN e n 0007NH

1.7 User interfaces

1.7.1 Digital inputs

Ten digital inputs are available for the elementary control
functions:

Positioning destination For saving positioning destinations, the SEC-AC possesses a

destination table in which the positioning destinations with
individual positioning profiles can be saved and from which
they can later be accessed. Four outputs serve for destination
selection, a fifth input is used as the starting input.

Hardware limit switches The hardware limit switches are used for setting safety limits

to the area of movement. During reference travel, one of the
two limit switches serves as the reference point for positio-
ning control.

Two inputs are used for the hardware-controlled final output
stage enable, as well as for the software-controlled regulator
enable.

A high-speed sample input can be used for synchronizing
tasks (master-slave mode).

1.7.2 Analogue inputs

The SEC-AC possesses two analogue inputs for the input le-
vel. The inputs have been designed as differential inputs, in
order to ensure a high degre of immunity to interference. The
analogue signals are digitized by the analogue-digital conver-
ter. The analogue signals serve for specifying nominal values
(speed or torque) for the regulator.

1-12

Festo P.BE-SEC- AC-HW-EN en 0007NH

1.8 Parametrizations

1.8.1 The parameter memory

The SEC-AC possesses two memory ranges in which it stores
parameters. The FLA SH memory is used for parameters which
are loaded when the controller is switched on or after R ESET.
These parameters are retained even when the power supply
is switched off. The internal memory (RAM) is used for para-
meters which are currently used for controlling. These para-
meters can be accessed with the parametrizing program.

The FLASH technology also enables a software update (e.g.
for customer-specific software) to be loaded into the RS 232
at a later data.

1.8.2 The parametrizing program

The parametrizing program is a program for parametrizing,
controlling and monitoring the operation of the SEC-AC via
communication interfaces. It can be used with every AT-com-
patible PC as from 80486-processor with at least 16MB main
memory, providing it is running with WINDOWS 95, 98 or
WINDOWS NT. User-friendly operation under WINDOWS also
facilitates work for users with only limited EDP knowledge.

1.8.3 CA N module (optional)

The optional CAN module operates in accordance with CAN-
OPEN specifications with the CIA-DS 402 positioning profile.

1.9 Monitoring functions

1.9.1 Brief description

The SEC-AC possesses an extensive arrangement of sensors
which monitor the faultless functioning of the controller unit,
the final output stage, the motor and the communication with
the peripherals.

Error memor Any faults which occur are saved in the internal error memory.

Most errors cause the controller unit to switch off the regula-
tor and the final output stage. The regulator cannot be swit-
ched on again until the fault has been rectified and the error
memory has been deleted by quitting (switch off the voltage
or actuate the r eset button above the figure display).

1.9.2 Monitoring the final ou tp ut stage

The final output stage is monitored by extensive protective
functions.

– Overcurrent and short-circuit monitoring:

This r eponds as s oon as the current in the intermediate
circuit exceeds twice the maximum current of the regula-
tor. Short circuits between two motor phases are recogni-
zedaswellasshortcircuitsatthemotoroutputterminals
in respect of the positive and negative reference potential
of the intermediate circuit and in respect of protective
earth. When the error monitoring recognizes an overcur-
rent, the final output stage is switched off immediately , so
that resistance to short circuits is guaranteed.

– Overvoltage monitoring for the intermediate circuit:

This responds as soon as the intermediate circuit voltage
exceeds the operating voltage range. The final output
stageisthenswitchedoff.

– Temperature monitoring for the heat sink: The heat sink

temperature of the final output stage is measured with a
linear temperature sensor. The regulator will be switched
off when a certain defined temperature is exceeded.

Festo P.BE-SEC- AC-HW-EN en 0007NH

1.9.3 Monitoring the motor

The SEC-AC possesses the following protective functions for
monitoring the motor and the connected rotary transducer:

– Monitoring the rotary transducer:

An error of the rotary transducer causes the final output
stage to be switched off. The carrier signal and the tracer
signal are monitored.

– Measuring and monitoring the motor temperature:

The SEC-AC possesses an input for registering and moni-
toring the motor temp eratur e.

1.9.4 I2t monitoring

The SEC-AC has I2t monitoring for limiting the medium loss of
output in the final output stage and in the motor. As the loss
of output occurring in the power electronics and in the motor
increases in the most unfavourable case in squared value
with the current flowing, the digitized current value will be
accepted as a measure of the loss of output.

1.9.5 Automatic braking

The SEC-AC can directly control a parking brake with limited
current consumption of up to 0.5 A. Operation of the holding
brake can be carried out automatically with programmable
delay times.

Please note

Connect the screening/shield with equal potential on the
mounting plate. If necessary, in the case of X10 or X11, use
an earthing screw above (e.g. with external regulators) and
always below.

Fastening screws must not be used as earthing screws.

The devices are intended as compact devices for mounting in
series in a control cabinet or on a wall. Any number of SEC-
ACs can be connected next to each other. The loss of output
occurring in operation, together with the heating of the device
depends on the output consumption. The cooling of the
SEC-AC is performed by free convection or by forced convec-
tion (only SEC-AC-508) with the series fan supplied. For suffi-
cient cooling, the upper and lower dimensions shown in Fig.
2/2 must be observed as a minimum.

Please note

The temperature sensor in the motor (normally-closed con-
tact) can be wired either via the the sensor cable or the
power cable (depending on the motor). The unused con-
nection remains in each case unwired.

In Festo drive packages the temperature sensor is wired
via the motor cable.

The parking brake is supplied with power by the power sup-
ply for the SEC-AC.

If the parking brake requires more than 0.5 A, it cannot be
supplied directly by the SEC-AC. The tolerances in the voltage
supply must also be observed (see section 2.2.).

If necessary, a relay must be inserted in the circuit between
the SEC-AC and the parking brake, as shown in the diagram
below.

Please note

The mating connector is included in delivery. There must
be a bridge on this plug between terminals RB- and RBI in
order that the internal braking resistors can be operated.

Warning

There is an intermediate circuit potential (up to 800V) at
these terminals! Select a suitably insulated cable. Before
starting work, switch off the device completely and wait 5
minutes. This br idge must be removed in order that the
external braking resistors can be operated. Simultaneous
operation of the internal and external braking resistors is
not possible. The bridge between RB- and RBI is already
fitted when the device is supplied from the factory.

The following external braking resistors are recommended:

Fitting the connecting cable

Please note

Connection to the mains power supply and the fitting of
mains switches, transformers, safety devices and network
filters may only be carried out by qualified personnel.

Caution

S Do not connect any cable to the electronics and do not

disconnect any cable while the system is still connected
to the power supply. Otherwise the device will be dam-
aged.

S Before installation, check all the cables once again, as

incorrect connection assignments may lead to serious
malfunctioning.

S Disconnect the SEC-AC and the motor from the mains

power supply and wait 5 minutes (for intermediate cir-
cuit discharge) before you connect or disconnect any
plugs.

S Always connect the SEC-AC to the protective earth (PE)

of the power supply network.

S Always connect the screening cables of the motor to the

earth connection of the SEC-AC before you commission
the motor.

Caution

Avoid the parallel routing of motor cables and signal
cables over long distances. Use only screened cables for
connecting the motor and paired twisted cables for the
signal cables.

3. Installation

3-19

Festo P .BE-SEC-AC-HW- EN e n 0007NH

In this way you will avoid electromagnetic interference which

can impair reliable operation of the system.

Caution

Make sure that the cables are fitted with strain relief. With
beam and multi-axis operation, mechanically stressed
cables must be laid in a drag chain.

Caution

The SEC-AC-508 does not have internal fuses for the
400V

AC

- or 560VDC-inputs. An automatic circuit breaker is
therefore provided. If the SEC-AC-508 is operated with only
one or two current phases, high PE-leakage currents may
occur. Only one automatic circuit breaker, in which all three
phases are switched off together, may therefore be used.

Caution

The SEC-AC must first be connected to X1, X10...X12. The
operating voltages for the intermediate circuit and the
electronic DC voltage supply must not be switched on until
commissioning is started. If the operating voltage connec-
tions are connected with incorret polarity, or if there is ex-
cessive operating voltage, or if the connections for the
operating voltage and the motor are swapped, the device
will be damaged. The SEC-AC must be connected to oper-
ating earth via the PE connection.

A 24 V power supply is required for operating the electronic
components of the SEC-AC. This voltage supply must be con-
nected to terminals 24V+ and 24V-. The power supply for the
final output stage must then be connected (either AC or DC is
possible at the appropriate input). The two power supplies
may be switched on simultaneously.

3.5 PE protective conductor and screening connections

3.5.1 Connecting instructions

The screening of the motor cable is wired together with the PE
inner conductor of the motor cable to the central PE connect-
ing point on the SEC-AC.

The PE connection to the network as well as the screening for
the resolver cable and, if applicable, the encoder cable, is
also wired to this star point. This star point must be con-
nected to the central earthing point of the complete c ontrol
cabinet by means of a cable (copper band) with a large cross-
sectional area (short cable to the assembly plate). The Festo
motor cable already contains this connecting band in the end
piece.

Special EMC protective measures must be observed in the
case of longer lengths.

Warning

For safety reasons, all PE protective conductors must be

connected before commissioning.
The PE connection to the network is wired to the central PE

connecting point on the SEC-AC.
Make sure that the earth connections between the devices

and the mounting plate are of sufficient dimensions to
enable HF interference to be discharged.

3.5.2 Electrical isolation

In designing the SEC-AC, we have placed great importance on
providing a high degree of immunity to interference. For this
reason, individual function blocks have been designed as
electrically isolated units. Signal transmission within the
SEC-AC is made via an optocoupler.

A distinction is made between the following isolated areas:

– the final output stage with intermediate circuit and net-

work input

– the control electronics with analogue signal processing

– the 24V supply and digital inputs and outputs

3. Installation

3.6 Measures for observing EMC guidelines

If correctly fitted and if all connections are correctly wired
with Festo cables, the regulators in the SEC-AC product family
will comply with the regulations of the relevant technical stan-
dards EN 50081 (interference emission) and EN 50082 (im-
munity to interference).

The interference emisson and immunity to interference of a
device always depend on the complete drive concept, which
consists of the following components:

– the power supply

– the SEC-AC controller

– the motor

– the electromechanical parts

– the design and type of wiring

– the higher-order controller

In order to increase immunity to interference and to reduce
interference emission, motor restrictors and network filters
have already been fitted into the SEC-AC, so that the regula-
tor as such fulfils the EMC requirements without additional
screening and filter measures, providing a suitable motor
cable is used (see chapter 3.1). This cable must not be longer
than 10 m.

If longer cables are used, we recommend that additional ex-
ternal network filters be switched in near to the device power
supply (e.g. from Schaffner).

Caution

If you touch D-SUB plug connecters which are not as-
signed, there is a danger of ESD (electrostatic discharge),
which can damage the SEC-AC or other parts of the sys-
tem. In order to avoid such discharges, you should use
protective caps which are obtainable from trade dealers.

4.2 Error messages of the SEC-AC

Caution

S Switch off the power supply before star ting error treat-

ment.

The SEC-AC possesses an error memory for saving and dis-
playing even short error signals, e.g. overcurrent. Errors can-
not be reset automatically by the SEC-AC. They must be
quitted by the user by means of the reset button above the
7-segment display.

All errors which occur are shown on the 7-segment dispay.
The flashing two-figure error codes clearly indicate the type of
error. If there are several errrors at the same time, the error
with the lowest code will be displayed. The following table
lists the error messages which can be displayed on the
SEC-AC.
