3.1 Introduction
The Process-Controller HPP-25 (riveting machine control unit combined with
process control) has been specially designed for the operation of BalTec riveting
machines.
In addition to simple riveting time control the HPP-25 can also control the riveting
modes with values monitoring.
Parameters ensure that various force and path measuring sensors can be used for
monitoring.
The HPP-25 is modular and can be extended with special modules or adapted with
a supplementary installed PLC to specific customer needs.
Thereby control and measurement procedures of the riveting process would be
accepted by HPP-25.
With the software "HPP25-PcTools", which is available as option, a large tool for
diagnosis, data logger, riveting curve display and data backup is available.
Description of software „HPP25-PcTool“ see separate operating instructions.

Setup operating mode
This operating mode serves for setup a new program in a new riveting
mode (S, T, F, E, N, H).
The riveting process lasts as long as the start signal is active – i.e. as
long as two-hand operating unit or foot switch are activated.
The process data during this period will be automatically registered and
displayed after the setup riveting.
The Process-Controller then changes automatically in Correction
operating mode.
Correction operating mode
The access to Correction operating mode happens automatically after
a setup riveting or if in the Cycle operation mode the key Correction
operating mode is selected.
The requirement for the control variable can be changed just like the
limits for the other process variables.
The riveting process is controlled according the control variable and
the evaluated variables are recalculated.
Activation of riveting process according parameter 85 adjustment
(continuous signal, pulse signal or bridging)
Note:
After following modification a correction riveting may be necessary:
- Modification of any control variable or other process variables
- Modification of operating pressure or riveting position
- Change of form tool
A correction riveting must always be executed with a new rivet.
Cycle operating mode
In Cycle operating mode the riveting process is stopped when reaching
the nominal value of the reference input variable.
The nominal and the actual values are displayed and are evaluated
according to riveting program.
If the control variable or one of the process variables is out of tolerance
the riveting is evaluated as NOK.

The input option and display of an analog value is adjusted by activation of
parameter 13 = 1 (analog module active).
A default analog value for new programs can be adjusted in parameter 14.
Example: Setup operating mode
riveting mode S1 with analog value
activation.
5.10.3 Analog value AN for pressure or speed selection
If a PVM module (see options) is installed in HPP-25, 2 analog values as outputs
are available:
1. 4 – 20mA, or
2. 0 – 700mA
Analog value AN input
The desired analog value can be entered in the field “AN” in the riveting program.
This analog value is only valid in the actual riveting program shown on the display.
This means, for each riveting program a different value can be adjusted.
Analog value AN for pressure selection
The analog value AN for pressure selection is a current between 4 – 20mA which
is visualised with 0 – 100% (0% = 4mA, 100% = 20mA). The proportional pressure
control valve will then set the air pressure “proportional” to the level of current resp.
percentage.
Example:
Machine is connected to air pressure which must have a minimum of 6 bar. The
proportional pressure regulating valve will set the maximum (according to the
information of the valve) to 6 bar (100%). This means, an analog input of 50%
corresponds approximately 3 bar.
Depending on the machine size, the minimum possible operation pressure is about
30% (2bar).
Analog value AN for speed selection
The flow rate for the approach speed of the riveting spindle is set by a volume flow
rate regulating valve (ex. RNE 481). The analog value AN for speed selection is a
current between 0 – 700mA which is visualised with 0 – 100% (0% = 0mA, 100% =
700mA). The volume flow rate regulating valve will then set the feed rate
“proportional” to the level of current resp. percentage.

5.10.5 Control variable offset value (OS)
The switch-off point of riveting cycle can be brought forward by entering an offset
value, so that the physically induced overshoot is compensated.
In this way the reached control value correspond as possible the given and the
displayed control variable.
The necessary offset value is determinated with a correction riveting (OS has to be
equal to zero) and then entered. The value must be positive.
Example (see picture):
S = 1.5mm, OS = 0.05mm
Riveting cycle will be stopped at S = S – OS = 1.50 – 0.05 = 1.45mm

The input option and display of the switching point is adjusted by activation of
parameter 73 = 3.
5.10.6 Rapid speed/working speed valve output switching point (SP) relative to control variable
The valve output for Rapid speed/working speed (PVM module required – X5) can
also be activated via a switching point.
The switching point (SP) is defined as value of control variable (mode S: starting
from a value S).
In addition to this well-known function Rapid speed/working speed (RNE 481 and
long-stroke machines) in connection with a proportional pressure control valve can
be switched on a lower pressure during the riveting process ( -> effect: How
"riveting out" on the stroke limiting stop).
Example
Mode S1
S
SP = 4.5mm (SP must be smaller than S
nominal
= 5.5mm
nominal
)
AN = 30%
The valve output switching point (SP) shall be set 4.5mm before reaching S
nominal
The riveting cycle will start with the max. pressure (the one shown on the input
manometer). When reaching the switching point SP, the pressure will drop to 30%
(set AN value) of the max. operating pressure and the rest of the riveting cycle (SP
= 4.5mm) will be executed with the lower pressure.
Input of switching point (SP) can be entered only in correction operation mode.
Result
The riveting cycle starts quickly forming the rivet with a max. pressure. When
reaching the switching point (SP), the pressure drops and ends the riveting cycle at
a low pressure, this means, the end of forming will need more time but it will
smoothen out the surface of the rivet.
The smooth finishing is used, when the rivet has not the same resistance over the
complete cycle, like for example hollow rivet which tend to buckle, when the
diameter gets bigger.

5.10.10 Rivet and component detection
With the function “Rivet and component detection“ the controller can check if a
component (by monitoring B) and a rivet (by NA and NX) is present.
Can only be done in riveting mode S2, T5 and H8 and by using the riveting stroke
limit switch unit NHE-U.
Following conditions can be analysed and evaluated by the controller:
Procedure example (riveting mode H8)
1. Set following parameters:
- 33 = 0 (path measurement E → path-measuring system at riveting
spindle)
- 75 = 2 (NHE for projection measurement)
- 88 = 2 (rivet and component detection active)
2. Use value B with tolerance to check the presence of component (base)
a) if value B is within the tolerance – carry on
b) if value B is outside the tolerance – carry on and check NX
3. Check rivet front end with function NX (see chapter “Rivet detection NX“)

5.10.11 Tolerance abort
Any violation of tolerances will stop immediately the riveting cycle when parameter
58 “tolerance abort” is activated in the control. Following settings are possible:
Parameter 58 = 0
Riveting cycle is stopped immediately only when NA, U or B tolerance is violated
Parameter 58 = 1
Riveting cycle is stopped immediately when any tolerance is violated.
Example for riveting mode S1
Parameter 58 = 0:
If NA is detected within the tolerance, the cycle continues until S = 3.19mm is
reached, even if riveting time T exceeds 0.7 seconds – until max. riveting time.
Parameter 58 = 1:
If riveting time T exceeds 0.7 seconds, the riveting cycle would be stopped
immediately and T is highlighted as error.
