6.6 Measuring impulse duration
(as of October 2005)
The length of the measuring impulses generated by the controller can be set with the parameter. 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 only be set by means of the ROPEX visualization software ( section 6.10 "Diagnostic inter-
face/visualization software (as of October 2005)" on page 32).
6.7 Automatic phase angle
compensation (AUTOCOMP)
(as of October 2005)
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.
The "AUTOCOMP" function must be activated in the ROPEX visualization software ( section 6.10 "Diagnostic
interface/visualization software (as of October 2005)" on page 32).
The following settings are possible:
1. „OFF" (Factory settings)
The „AUTOCOMP“ function is deactivated.
2. „ON“
The „AUTOCOMP“ function is executed whenever the "AUTOCAL" function ( section 6.4 "Automatic zero
calibration (AUTOCAL)" on page 25) is run 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 2.0s. The second
"AUTOCAL" function only takes around 2.0s and incorporates the "AUTOCOMP" function.
If the interval following a successful "AUTOCAL" function is longer than 2.0s, the display returns to the home
position without executing the „AUTOCOMP“ function.
