Software project planning
Project planning
The creation of a parameter file forms the basis for the func-
tion of the HACD. The parameter file contains the block struc-
ture of the HACD in which the links of the variables will be
created. The parameter files are created in BODAC. The
parameter file can be created offline and transferred to the
HACD by means of a PC.
This software project planning is implemented according to
the following steps:
1. Selection of the HACD.
2. Application is defined by means of the block structure.
3. Setting of the parameter values (sensors, controllers...).
4. The data is sent to the HACD.
5. Storage of the data in the flash.
6. The setting and the machine sequence are optimized at
the machine.
PC program BODAC
For the implementation of the project planning tasks, the
BODAC PC program is available to the user. It serves the
programming, setting, and diagnosis of the HACD.
Scope of services:
– Comfortable dialog functions for setting the machine data
online or offline
– Dialog window for setting the parameter values online
– Comprehensive options for displaying process variables,
digital inputs, outputs, and flags
– Recording and graphical presentation of up to eight pro-
cess variables with great selection of trigger options
PC-System requirements:
– Windows XP, Windows Vista, Windows 7
– Random access memory (256 MB recommended)
– 250 MB free hard disk capacity
Note:
The BODAC PC program is not included in the scope of de-
livery. It can be downloaded in the Internet free of charge!

Functional description
The VT-HACD-3-2X closed-loop control electronics is a mod-
ule that is installed on a top hat rail.
A microcontroller controls the entire process, makes adjust-
ments, establishes links and realizes the closed control loops.
Data for configuration, command values and parameters are
stored in a FLASH in a non-volatile form.
The entire configuration and the parameterization and diag-
nosis are carried out via the BODAC PC program. Apart from
the switches for the address setting, the module does not
contain any other hardware switches. For the configuration,
the HACD has to be connected to a PC via a serial interface
(RS 232, 1:1 cable).
The configuration and thus the creation of applications are
very simple - you just have to link pre-defined functional com-
ponents. For this purpose, no programming knowledge is
necessary.
One mode is available:
• Structural editor
Own motion sequences can be created. For this purpose,
32 blocks are available. Each block contains: Command
value, ramp times (velocity ±, acceleration ±) and controller
parameters.
Blocks are activated by setting trigger conditions: Set-
ting digital inputs, comparing signals with freely definable
thresholds or expiry of waiting periods.
Signal links [6] [8] [17]
The HACD offers numerous possibilities for linking signals on
the input and on the output side, whereas it is in each case
possible to link 2 signals. This includes functions like addition,
subtraction, multiplication, division as well as minimum/maxi-
mum value generator, area ratio and limiter:
+ = Addition: Z = X + Y
– = Subtraction: Z = X – Y
* = Multiplication: Z = X * Y / 100
/ = Division: Z = X / Y * 100
MIN = Minimum value generator: Z = MIN (X, Y)
MAX = Maximum value generator: Z = MAX (X, Y)
RATIO = Entry of a ratio:
for RATIO >1: Z = X * RATIO – Y
for RATIO <1: Z = X – Y / RATIO
(e.g. area ratio with pressure differential measurement)
LIMIT = Signal limiter: Z = MIN (|X|, |Y|) * sign (X)
JUMP = Jump generator: Z = MAX (|X|, |Y|) * sign (X)
with Z … Result
X … 1st signal
X … 2nd signal
T1 Lag = Low-pass filter
Analog I/O [1] [15]
For the 6 analog inputs, you can switch between ±10 V,
0…10 V, 0…20 mA by means of the software.
For the analog output AO1, you can switch between ±10 V,
0…10 V, 0…20 mA and 4...20 mA by means of the software.
AO2 and AO3 are fixedly set to ±10 V.
The switching is performed by utilizing the whole range of the
analog-digital converter.
For all analog inputs, working range and error detection can
be defined.
The analog outputs can be adjusted by means of amplifica-
tion and offset.
Digital I/O [3] [16]
The HACD has 9 digital inputs and 8 digital outputs.
An input has the fix functionality Release, a digital output the
fixed functionality OK.
The other digital inputs are used for triggering blocks (see
blocks and triggering).
The function of each digital output can be determined by
means of selection from a pre-defined list:
• Command value = Actual value
• Actual value larger or smaller than an adjustable threshold
• Waiting period expired
• Ramp active
• Internal flag set
• Error flag set
• Table ended
• Error status
• Block timeout
• Controller active
• Absolute value (actual value) < window
• Absolute value (command value) < window
• Incremental home position

Functional description (continued)
Digital position measurement system
When using the VT-HACD-3-2X as closed-loop control elec-
tronics, digital position measurement systems of type SSI or
incremental can be used for recording the actual value.
Limitations of use incremental encoder
The maximum frequency of the incremental encoder input (fG)
of the HACD is 250 kHz. The maximum travel velocity of the
drive, the resolution (res) of the encoder system used and the
possible signal analysis by an EXE (interpolation and digitali-
zation electronics) determine the frequency.
Determination formulae
Encoder resolution with given maximum velocity:
fG [kHz] x EXE
Res [μm] ≥ v m x 103
s
Velocity with given encoder resolution:
Res [μm] x EXE x fG [kHz]
v m ≤
s103
Controller
If the HACD is used as closed-loop control electronics, the
“Controller” entry has to be selected in the signal linking [8].
The LCx signals constitute the command value branch, the
LFBx signals the actual value branch. [8]
As actual value signal, you can use both, an SSI encoder or
incremental encoder [2] digital measurement system or one
or several analog sensors.
The controller structure is designed as PIDT1 controller,
whereas each component can be activated or deactivated in-
dividually. In this way, you can, e.g. also realize a P or PT1
controller. The I component can moreover be controlled via a
window (upper and lower limit).
Controller parameters can be set in a block-wise or in a block-
independent form.
A state feedback can be used for dampening the controller
output.

Adjustment to hydraulic system
For the optimum adjustment to the particularities of hydraulic
drives, the following functions are implemented upstream the
analog output:
• Direction-dependent gain [10]
For positive and negative values, the amplification can be
set separately. In this way, adjustment to the area ratio of a
single-rod cylinder is possible.
• Characteristic curve correction [11]
In this way, the progressive flow characteristic of propor-
tional directional valves is compensated or an inflected
characteristic curve is realized.
• Overlap jump/residual velocity [12]
When using valves with positive overlap, a fine position-
ing can be used in case of a PDT1 controller in order to
increase the static accuracy. This fine positioning can be
selected according to the residual voltage principle and as
overlap jump.
• Zero point correction (offset) [13]
Serves the correction of the zero point of the connected
proportional servo valve.
Error detection and troubleshooting
The HACD supports numerous error monitoring possibilities:
• Monitoring of the analog inputs for undershooting or ex-
ceedance of the range
• Monitoring of the sensors for cable break
• Control error monitoring in case of configuration of the
HACD as controller
• Monitoring of the supply voltage, all internal voltages as
well as of the +10 V reference voltage
• Monitoring of the microcontroller itself (watchdog) as well
as of the accumulator (check sum)
The error monitors as well as their reaction can be config-
ured, as well.

Maintenance instructions:
– The devices have been tested in the plant and are supplied with default settings.
– Only complete units can be repaired. The repaired units will be supplied with default settings. User-specific settings are not
maintained. The operator will have to re-transfer the corresponding user parameters and programs.
Notes:
– Electric signals taken out via control electronics (e.g. signal “No error”) may not be used for the actuation of safety-relevant
machine functions! (See also the European standard “Safety requirements for fluid power systems and their components -
Hydraulics”, EN 982.)
– If electromagnetic interference must be expected, take appropriate measures to safeguard the function (depending on the
application, e.g. screening, filtration)!
– For more information refer to the BODAC software description 30543-01-B and the 30543-B operating instructions
– The upper and lower ventilation slots must not be concealed by adjacent units in order to provide for sufficient cooling.
