8.7.5
Heating time limit
The heating time limit provides additional protection against unwanted continuous heating. The controller auto-
matically deactivates the heating impulse after the set heating time limit has elapsed if the ST bit remains set for
longer than the time specified with this limit. The ST bit must be reset before the controller can be started up again.
The heating time limit is deactivated by default (0) but can be set to any value between 0 s and 99.9 s (0 and 999).
8.7.6
Measuring impulse duration
The length of the measuring impulses generated by the controller can be set with this parameter. It may be nec-
essary to set a measuring impulse longer than the default 1.7 ms for certain applications.
8.7.7
Data format
This parameter specifies the order of the bytes ("Little Endian (Intel)” or "Big Endian (Motorola)") in the cyclic data;
this setting applies to both input and output data (
section 8.4 "Communication protocol" on page 23).
We recommend selecting "Big Endian (Motorola)" for Siemens PLCs.
8.7.8
Automatic phase angle compensation (AUTOCOMP)
It may be necessary to compensate the phase angle displacement between the U
R
and I
R
measuring signals for
specific heatsealing applications (
ROPEX Application Report). The AUTOCOMP function is provided for this
purpose. The following settings are possible:
1.
"Off"
(factory setting)
The AUTOCOMP function is switched off.
2.
"On"
The AUTOCOMP function is executed whenever the AUTOCAL function (
section 8.5.1 "Automatic zero cal-
ibration AUTOCAL (AC)" on page 23) is executed twice in quick succession. The interval between the end of
the first AUTOCAL function and the start of the second AUTOCAL must be shorter than 2.0 seconds. The
second AUTOCAL function only takes around 2.0 seconds and includes the AUTOCOMP function.
If the interval between the two AUTOCAL functions is longer than 2.0 seconds, AUTOCAL is executed normally
again the second time.
