Measuring impulse length (as of February 2007)
The length of the measuring impulses generated by the controller can be set with this parameter (CAN message
address 12). It may be necessary to set a measuring impulse that is longer than the default 1.7ms for certain
applications (
ROPEX Application Report).
This parameter can be set either via the CAN interface (CAN message address 12) or in the ROPEX
visualization software (
section 10.12 "Diagnostic interface / visualization software (as of February
10.8
Automatic phase compensation (AUTOCOMP, as of February 2007)
It may be necessary to compensate the phase angle displacement between the U
R
and I
R
measuring signals in
certain heatsealing applications (
ROPEX Application Report). The "AUTOCOMP" function is provided for this
purpose (CAN message address 13).
The following settings are possible:
1.
"OFF"
(factory setting)
The "AUTOCOMP" function is deactivated
2.
"ON"
The "AUTOCOMP" function is executed whenever the "AUTOCAL" function (
section 10.3.3 "Automatic zero
calibration (AUTOCAL)" on page 36) is run twice in quick succession. The interval between the end of the first
"AUTOCAL" function and the start of the second "AUTOCAL" function must be shorter than 2.0s. The second
"AUTOCAL" function only takes around 2.0s and includes the "AUTOCOMP" function.
If the interval between the two "AUTOCAL" functions is longer than 2.0s, "AUTOCAL" is run without
"AUTOCOMP" the second time.
