Description
Displays actual tension estimated by the Virtual roll function.
The unit is selected in parameter
selection.
This parameter is read-only.
Estimated tension.
Displays the position of the dancer arm.
This parameter is read-only.
Dancer arm position.
Displays target position reference for dancer.
This parameter is read-only.
Target dancer position set point.
Displays dancer position reference currently in use with
regard to actual control mode and ramp settings.
This parameter is read-only.
Current dancer position set point.
Selects the unit for tension measurement.
Tension measurement in Newton or lbf (if
= Imperial).
Tension measurement in Newton/meter or lbf/inch (if
74.91 Unit system = Imperial).
Source selection (see Terms and abbreviations
page 152).
PID controller settings.
See section Process PID control
Enables tension control mode (parameter
control mode) to Open loop.
Tension control in open loop mode is disabled.
Tension control in open loop mode is enabled.
Source selection (see Terms and abbreviations
page 152).
Enables only P control.
Normal PID control is active.
Forces the controller to use only P-term for regulation. I-term
and D-term are inactive.
Source selection (see Terms and abbreviations
152).
Defines absolute boundaries for the PID controller output
before trimming.
PID controller output.
Defines proportional gain setting for the PID controller. If
parameter 78.14 PID adaptation
in this parameter is interpreted as P-gain, effective when
actual diameter is equal to parameter
Proportional gain.
