2Introduction
This document describes the possibilities and the properties of the EM-RES-02 expan-
sion module for the frequency inverters of the ACT and ACU device series.
Note: This document exclusively describes the EM-RES-02 expansion module. It
is not to be understood as fundamental information for the operation of
the frequency inverters of the ACT and ACU device series.
The EM-RES-02 expansion module is an optional hardware component to extend the
functionality of the frequency inverter. It enables the data exchange within the net-
work between the components which have been directly connected, for example con-
trol and regulation elements.
The EM-RES-02 expansion module is supported from device series ACU and as
from software version 4.1.0 of device series ACT.
The EM-RES-02 module extends the functionality of the frequency inverters of the
ACT and ACU device series by the following additional functions:
−Analog input
(second bipolar analog input)
−Resolver input
−Repetition frequency output
Note: The EM-RES-02 expansion module has been enclosed with the frequency
inverter as a separate component and must be fitted by the user. This is
described in detail in the chapter "Mechanical Installation".
To assemble the expansion module it can be simply plugged into the frequency in-
verter of the ACT and ACU device series.
Warning! The assembly is done before the frequency inverter is put into operation,
and only in a voltage-free state.
The pluggable sockets of the expansion module enable economical overall fittingwith
a safe function.

4.1 Analog input EM-S1INA
4.1.1 General
The analog input of the EM-RES-02 expansion module can optionally be confi
g
ured as
a voltage or a current input. Parameterization of the input signal is done by the defini-
tion of a linear characteristic and assignment as a
−reference value source
(can be selected via the parameter Reference frequency source 475),
−reference percentage source
(can be selected via the parameter Reference percentage source 476),
−actual percentage source
(can be selected via the parameter Actual percentage source 478, in configura-
tion x11) or
−limit value sources
(can be selected via the parameters 734…737).
4.1.2 Configuration voltage/current input
The analog input of the EM-RES-02 expansion module has been confi
g
ured in the
factory setting for a voltage signal of +/- 10 V. Switch S3 enables a switch-over of the
operation mode for an analog current signal of +/-20 mA.

4.1.3 Characteristic
The mapping of the analog input signals onto a frequency or percentage reference
value is possible for various demands. The parameterization is to be done via two
points of the linear characteristic of the reference channel.
T
he characteristic point 1, with the coordinates X1 and Y1, and the characteristic point
2, with the coordinates X2 and Y2, can be set in four parameters.
T
he characteristic points X1 and X2 are stated as percenta
g
es, as the analo
g
input can
be switched as a current or voltage input via switch S3.

567 Characteristic point Y2 -100.00 % 100.00 % 100.00 %
The coordinates of the characteristic points are related as a percenta
g
e to the analo
g
signal, with 10 V or 20 mA, and the parameter Maximum Frequency 419 or parame-
ter Maximum reference percentage 519. The chan
g
e of direction of rotation can be
done via the digital inputs of the frequency inverter and/or by selecting the character-
istic points.
The definition of the analog input characteristic can be calculated via the two-poin
t
form of the straight-line equation. The speed Y of the drive mechanism is controlled
according to the analog control signal X.

Behavior 563 demands a check of the characteristic parameters. Sensible
use is only possible if the Characteristic point X1 564 is in the positive
range.
4.1.4 Operation modes
The operation modes of the analog input characteristic enable application-related scal-
in
g
as a supplement to the characteristic points stated. One of the four linear types o
f
characteristic is selected for adaptation of the si
g
nal for the analo
g
input si
g
nal via the
parameter Operation mode 562.
If the characteristic points are not suited for the type of characteristic selected, the
characteristic points are corrected internally.
Operation mode Function
1 - bipolar The analog input signal is mapped onto the reference
figure according to the characteristic points (X1/Y1)
and (X2/Y2).
11 - unipolar With a negative parameter value of the characteristic
points X1 or X2, they are mapped to the reference
value zero.
21 - unipolar
2…10 V / 4…20 mA If the characteristic points X1 or X2 have been set with a negative parameter figure or smaller than 0%,
the input characteristic is mapped to the reference
value 20%.
101 - bipolar absolute value Negative parameter values of the characteristic points
Y1 or Y2 are mapped as a positive reference value in
the characteristic.
Further information on the operation modes stated in the table can be found in the
following chapter "Examples“.

12 08/06
4.1.4.1 Examples
The analog input signal is mapped onto a reference value as a function of the charac-
teristic. The following examples show the operation modes for an analog voltage sig-
nal. The parameter Minimum Frequency 418 is set to the value 0.00 Hz. The charac-
teristic point 100% for the Y-axis corresponds to the parameter Maximum Frequency
419 of 50.00 Hz in the examples.
Attention!

of the parameterized characteristic points. In the followin
g
examples, the
areas of the coordinate system from which a characteristic point is dis-
placed are marked.
Operation mode "1 – bipolar"
In operation mode "1 – bipolar“, the characteristic of the analo

4.1.7 Error and warning behavior
The monitoring of the analog input signal necessary accordin
g
to the application is to
be configured via the parameter Error/Warning behavior 563.
Operation mode Function
0 - Off The input signal is not monitored.
1 - Warning < 1 V / 2 mA If the input signal is less than 1 V or 2 mA, there
is a warning message.
2 - Shutdown < 1 V / 2 mA If the input signal is less than 1 V or 2 mA, there
is a warning message, the drive mechanism is
decelerated according to stopping behavior 1.
3 - Fault switch-off
< 1 V / 2 mA
If the input signal is less than 1 V or 2 mA, there
is a warning and fault message and the drive
mechanism stops freely.
T
he monitorin
g
of the analo
g
input si
g
nal is active independent of the release of the
frequency inverter according to the operation mode selected.
In operation mode 2, the drive mechanism is decelerated independent of the stoppin
g
behavior set (Parameter Operation mode 630) accordin
g
to stoppin
g
behavior 1
(shutdown and switch-off). If the set holding time has expired, there is a fault mes-
sage. A repeat start of the drive mechanism is possible by switchin
g

and off if the fault has been cleared.
Operation mode 3defines the free stoppa

630.

j
ust the analo
g
input.
Parameter Adjustment 568 is used for this purpose.
Operation mode Function
0 - no adjustment Normal operation
1 - Adjustment 0 V / 0 mA Adjustment of the measurement with an analog
signal of 0 V or 0 mA.
2 - Adjustment 10 V / 20 mA Adjustment of the measurement with an analog
signal of 10 V or 20 mA.
Example of the adjustment of the analog input with a voltage signal:
Note:
T
he measurements for the ad
j
ustment are to be done with a suitable
measuring instrument and the correct polarity.
If not, faulty measurements can result.

•Apply 10 V to the analog input, e.g. with a wired link from the socket of the ana-
log input to socket X210B.5 (reference output 10 V) of the frequency inverter.
•Select operation mode "2 - Adjustment 10 V / 20 mA“.
4.1.9 Filter time constant
The time constant of the filter for the reference analog value can be set via the pa-
rameter Filter time constant 561.
T
he time constant states the time for which the input si
g
nal is avera
g
ed by means of a
low pass filter, e.g. in order to eliminate fault effects.
The setting range is a range of values between 0 ms and 5000 ms in 15 steps.
Operation mode Function
0 - Time constant 0 ms Filter deactivated – analog reference value is for-
warded unfiltered
2 - Time constant 2 ms

4.2 Resolver input EM-RES
The resolver input is used for evaluating the position information from the resolver.
The frequency of the field signal for the resolver can be selected via parameter Opera-
tion Mode 380.
Operation mode Function
5- frequency 5 kHz
10- frequency 10 kHz
20- frequency 20 kHz

range of 0°...360° several times during one mechanical revolution.
For the detection of the position an
g
le of the rotor at a synchronous motor, the ratio
of the no. of motor pole pairs to the no. of resolver pole pairs must be an integer.
The no. of pole pairs of the resolver can be adjusted via parameter

4.2.1 Offset
In order to enable the start of a synchronous machine, the absolute position of the
rotor must be known. This information is required in order to actuate the stator wind-
ings in the right order depending on the position of the rotor. The position of the ro-
tary field in the synchronous machine must be controlled in order to obtain a continu-
ous movement of the rotor. During first commissioning, the position of the rotor wind-
ing of the resolver is adjusted to the rotor displacement angle of the synchronous mo-
tor by ad
j
ustin
g
the offset. For operatin
g
a synchronous machine with resolver, the
offset must be adjusted in order to obtain perfectly true runnin
g
and a maximum
torque.
The correct Offset 382 is adjusted when the flux-forming voltage 235 reaches the
value 0 (approximately) while the motor is turning.

•Set parameter Operation Mode 380 to the frequency value of the field si
g
nal fo
r
the resolver.
•Adjust parameter No. of Pole Pairs 381 to the number of pole pairs of the re-
solver.
Before adjusting the offset, take the following safety precautions:
•Disable the frequency inverter via digital input S1IND (controller release).
•If possible, uncouple the motor from the load so that the motor shaft turns freely.
If installed, release the mechanical brake.
If uncoupling is not possible, make sure that the motor is loaded as little as possi-
ble.
Warning! In certain circumstances, the motor speed may reach hi
g
h values. If the
motor is not uncoupled from the load, personal and material dama
g
e
may result. To avoid such dama
g
e, make the followin
g
settin
g
s in any
case.
•Set the max. permissible output frequency of the frequency inverter to a low fre-
quency value via parameter Switch-Off Limit 417. Select the frequency value such
that uncontrolled acceleration of the motor ("overspeedin
g
") is detected at an earl
y
stage. This limitation is necessary in order to avoid personal and material damage.
•Set parameter Current Limit 728 of the speed controller to a low current value
(e.
g
. 10% of the rated motor current). In this way it is made sure that there are no
excessive currents of the offset is set incorrectly.
•Turn motor shaft manually. Check the sense of rotation of the resolver via the ac-
tual value of parameter Frequency Speed Sensor 2 219. In the case of a clock-wise
rotation of the motor shaft, positive values are displayed for the actual frequency
value. If the displayed sense of rotation does not correspond to the actual sense o
f
rotation, change the connections SIN+ and SIN- at socket X410A of the frequenc
y
inverter.
The Offset 382 must be between 0° and 360°, divided by the number of motor pole
pairs. If the number of resolver pole pairs is higher than 1, the possible range is be-
tween 0° and the max. offset.

•Adjust a low reference speed value (approx. 10% lower than the Switch-off Limi
t
Frequency 417), and enable the frequency inverter via digital input S1IND (con-
troller release) and S2IND (start clock-wise operation) in order to accelerate the
motor.
